"If you're ever in such a facility and a tornado hits, hide in a truck" is my take from this video.

Edit: it’s a bad take, read below.

That's an absolutely terrible idea. Trucks are built with thin metal and probably have objects inside, not to mention could be easily lifted off the ground and thrown. In areas that are susceptible to tornados buildings are usually supposed to be built with at least one or two areas that have no windows and reinforced surroundings to hide when tornado alarms go off.
Yes there definitely was an interior bathroom designed as tornado shelter in this building. While it may or may not have stayed intact, it was your best chance at survival.
I’m pretty sure their comment was based on the almost flawless looking trucks in the rubble…
That is interesting but for all we know there was another row of trucks in the middle part that got picked up and thrown for miles.

My Oklahoma high school took a direct hit from a tornado and cars in the parking lot were found wadded up all over town. If a tornado can pick up an Oldsmobile it can pick up a Sprinter.

Refer to these photos of what a tornado does to a truck. https://www.washingtonpost.com/photography/interactive/2021/...

Which are only there because tornadoes are extremely local events, you can be very close to the destruction and come out unscathed. Like it can reduce your house to toothpicks and leave your neighbors house entirely unharmed.
Correct. Also I’m ignorant about tornadoes.
That’s actually a really damn good point! I didn’t expect to see much from the video that wasn’t in the title, but I was struck by how complete the damage was in the tornado path; both sides of the building still there, and the middle so completely flattened, save the trucks.
Par for the course with tornados. Things stand that shouldn’t and thing that should have stood, don’t.
I’m not entirely sure what should or shouldn’t stand, but I guess I would speculate warehouse walls have a much higher surface area to mass ratio than cars, it certainly makes some sense to me that the building could go while the cars could stand, maybe especially if it’s less than EF4/5, no?
I grew up in the northern Midwest, where tornados happen semi-regularly. If you’re facing a tornado and in a vehicle, you’re supposed to abandon the vehicle and get to a ditch or some other low point that provides solid sideways protection and lay down as flat as you can.

Tornados are weirdly destructive. Some things that get directly hit survive when they shouldn’t. Vehicles are not built to take the damage even a small tornado brings.

https://www.spc.noaa.gov/faq/tornado/safety.html

Aren’t there a lot of roads in the Midwest that have ditches for this reason? That page does seem to suggest that if you don’t have a ditch lower than the roadway nearby, staying low inside the car might be better than getting out, due to deadly flying debris? You’re toast if the vehicle takes flight, of course, but I guess statistically that’s not super common?

* bewildered by the downvotes, but just to clarify, the NOAA page says explicitly: “In a car or truck: […] If you are caught by extreme winds or flying debris, park the car as quickly and safely as possible -- out of the traffic lanes. Stay in the car with the seat belt on. Put your head down below the windows; cover your head with your hands and a blanket, coat, or other cushion if possible.”

No. The ditches are for water drainage and Dragula's.
High winds are not tornadoes, these are very different circumstances. You are trying not to get hit by a tornado, and if you do trying not to get relocated by one, or you’re trying not to get hit by something thrown by a tornado. A high wind isn’t going to throw a house at you or a shard of metal though a tree, a tornado will. There are small ones that are mostly harmless and will at most knock over some corn, it’s hard telling the difference between one of those and one that will pick you up and throw you a quarter mile.

Absolutely do not hide in a vehicle from a tornado. You want to be low and near something well anchored. Inside a ditch, huddled up next to an overpass foundation, etc.

A tornado either hits you it doesn’t, but few people in places where there are tornadoes are going to be dumb enough to be near one in a vehicle. You can avoid them while in your vehicle but even seasoned storm chasers still sometimes get taken.

Source: Iowa raised, been a handful of meters away from a weather event that lifted and shifted a couple of buildings a foot off their foundations and peeled a section of roof from a barn. It may have been a microburst instead of a tornado, it was quite dark at the time.

And no, the ditches are there for water drainage like the other poster said… though I’m not sure about vampires :)

Just to add, straightline winds (not tornadoes) do not change direction suddenly. A car is very aerodynamic, and if you face into the straightline wind with it, it's a good place to be.

Tornadoes on the other hand are circular (roughly). Plus subvortices inside of the tornado make for unpredictable and turbulent wind.

Your car may handle the 200mph wind fairly well in one direction, but the next second it hits you at a right angle and bye bye.

As a small child, I once spent time lying in a ditch while visiting relatives who lived in a Tornado prone region. We got in the ditch because it was after dark and we could hear a tornado getting close but we couldn't see anything. We were lucky that it passed close to our farm but not upon us. The chaos and the violence of the wind and noise was terrifying. The visible path through the woods nearby the next morning had an alien feel to it. I remember the smell of tree sap from the many trees broken off and ripped apart. I feel so much for the many folks that endured those storms last night.
A guy I knew in college was in a truck when a tornado hit and it threw that truck like an angry toddler with a hot wheels. They found the truck more than a mile away. The guy wasn’t even in it anymore. They found him in several locations.

DO NOT get in a car for safety in a Tornado.

Your comment is BS on the order of "I know a guy who didn't die in an accident because he wasn't wearing his seat-belt and was thrown clear"

Vehicle cabins are far stronger than all but the most heavily built of above ground structures. They are expressly designed to be as survivable as possible in the kind of rollover accident that being tossed by wind is similar to. Furthermore, there's negligible chance of being killed by the car itself sustaining damage. This is very much not true about any sort of building. You might not get tossed in a stick build structure or steel warehouse style building but does that really matter if a wall or pallet rack falls on you?

Of course a purpose built shelter or below ground level area is better but if those aren't available a car is your next best option.

There was another case at the University of Maryland some years back. Two women were in a car that got picked up and tossed over (or into?) some trees. They did not survive.

https://en.wikipedia.org/wiki/Tornado_outbreak_of_September_...

"Tragically, [the victims] had just left the building and were driving away when the funnel picked them up and carried the car several hundred yards, over one of the high-rise dorms, before dropping the car into the woods beyond."

That is a very bad take. What you are seeing are only those trucks that survived--because the trucks that didn't survive are too badly mangled to identify as trucks. If you look at some of the later pictures in this photo deck (https://fox2now.com/news/illinois/photos-tornado-destroys-ed...), you can make out several trucks whose occupants would be dead. At least one truck appears to be sheared cleanly in two. The trucks that survived appear to have done so largely because they were out of the main debris field.
Good to know, thanks for that!
If you hid close to the floor in front of the driver's seat and covered your head you'd stand a very good chance of being able to walk out. Even though the back is gone on a lot of those vehicles that section is just large flat walls that aren't really structural and are only built to stand up to wind and rain while driving. Hide in the part of the vehicle made to protect occupants from oncoming traffic.
Ideally, you want to be inside a windowless, concrete structure that's built into the ground. The closest thing like that that's typically available to people is a basement, which is why the advice is to go to the basement in a house that has one.
Brutal night throughout the region. From the photos I've seen, the candle factory in Mayfield is the worst-hit; storm shelters can only do so much.
Ah, so that's what Amazon means when they tell you your stuff is safer in the cloud.
Rescuers were relieved to discover that many of the apparent injuries in the fulfillment center were only Wicked Witch of The East Legs Props.

I'm not sure comedy is appropriate when at least two people died during this.
Humor is one of the ways humans process tragedy. Our modern culture's hostility to humor makes the emotional aftermath of tragedy worse by removing this coping mechanism.
When it comes to random people on the Internet making jokes about mass casualty events, it certainly feels more like callousness than coping.
Pain that one shares makes for great humor. Pain that one does not makes for uncomfortably bad humor.
Dumb question, but is it even feasible to build such a building in a "tornado-proof" way? From how the damage looks, that warehouse must have only been metal walls and roofing instead of solid concrete or bricks...
Tornado proof? No. But you can build shelters (eg underground) to provide safety when the building overhead is destroyed.
It's definitely feasible, you basically just end up with something very similar to a military bunker. The structure ends up being mostly underground and the entrance or above ground areas are mostly made of reinforced concrete with heavy steel doors, no windows, etc.

It's also possible to make tornado proof residential homes, but they're expensive and not very appealing: https://www.huffpost.com/entry/tornado-proof-homes-oklahoma_...

Spent five minutes googling (so now I'm an expert! /s). So much spam on this topic. The most reasonable answer I found so far kindof matches up with your answer:

https://www.quora.com/How-hard-would-it-be-to-build-tornado-...

So first off, to survive the wind speeds of an F-5 tornado wouldn’t be hard to build. This issue is more about price than difficulty. Add extra fasteners, sturdier materials, etc. Once you get the foundation properly anchored and the frame reinforced, the rest is very simple.

The real issue is with the debris. Imagine a tree being tossed into the house. Even IF you built the walls to withstand it, which would be insane in a residential structure, you still have doors, windows, etc. Unless you build underground, or spent 5x more for a tiny house, it would be near impossible.

Your best bet is to not build in the middle of a tornado-prone area.

(comment deleted)
Some types of tornado proof homes are not the big square concrete type, like shown in the sibling comment article, but dome homes made out of concrete. The obvious issues are that most furniture doesn’t fit well, wall hangings don’t work correctly, and putting in interior walls is wasteful, while modifying anything for electric or water is quite difficult without careful planning.
I’ve been in several buildings designed to withstand tornados. Anything above around typically is only designed to survive and F3 or F4. The ones I’ve seen have a strong outer shell of steel and concrete with some angles to help deflect wind. There’s then an inner shell of steel designed to keep what ever is inside safe. The outer shell will let some debris through but it won’t penetrate the inner concrete and steel shell.

To put it in perspective an F5 (strongest tornado) will leave just dirt behind and all structures, vegetation, and soil will be gone.

Here’s an example of an F5 aftermath in Illinois in the 90s

https://www.weather.gov/images/lot/pastevents/1990/Aug28/pla...

You don't want a concrete or brick home in an area with any seismic activity though. There's really no perfect shelter for all potential disasters.
In America the tornado areas and the earthquake areas don’t really overlap much at all.
That depends on how quiet the New Madrid fault really is.
Both at once would be quite a shitshow. Soil liquefaction floats your tornado shelter right out of the ground, then the tornado smashes it. I can't imagine what it would take to survive both at once. Thankfully both at once would be extremely unlikely.
Possible? Yes. Practical? Eh…

You either need very thick castle kinds of walls or to sink underground and essentially build a big hobbit hole kind of construction where wind hits a gentle slope instead of a flat wall.

A building designed to take an 80 mph wind is just a lot different than one to take a 250mph wind. One is basically guaranteed and the other an extreme rarity.

Financially, no it is not feasible. In the parts of the US where tornadoes are common, any particular spot is hit by a tornado on average once every 2,500 years. Of those tornadoes, 80% of them will be EF0 or EF1 intensity. An EF1 tornado will cause some roof damage and break windows but it won't tear the roof completely off or collapse walls.

So it doesn't really make sense to spend money for something that happens once every few thousand years and is typically pretty minor when it happens. Especially given that it is usually completely predictable when it happens. Tornadoes don't suddenly appear out of a blue sky. There were warnings for the last few days that storms capable of producing tornadoes were likely for the areas that were hit last night. When the storms were going on, the TV networks interrupted programming and had the weather forecasters tell where the storms were and where they were headed next. Tornado sirens would have been going off long before the tornadoes hit. People would be getting texts on their phones warning them to take cover.

If you're in a well-built structure, you're going to be fine in most tornadoes. Even for EF2 or EF3, you would most likely be OK even in a house without a basement if you took shelter in an interior closet on the ground floor. If you're in a mobile home, you're toast. For an EF4, you have a decent chance if you are in an interior room in a basement. So for the vast majority of tornadoes, which are already rare, there isn't much reason so spend money to protect property when there is already a way to protect lives.

For EF5 tornadoes, it would be challenging to build anything other than an underground bunker to withstand them. They are incredibly rare, Wikipedia says 59 in the US since 1950. An EF5 tornado doesn't just level a house, it rips it from the foundation, sends it flying through the air and shatters it into a million pieces. Here's what an EF5 tornado does to a house: https://www.spc.noaa.gov/faq/tornado/f5.htm. It can rip the asphalt from a roadway and send it flying through the air. If you're in a building in the path of an EF5 tornado, you are probably best off following the advice my redneck step dad gave me when I was a kid for what to do in the case of a nuclear attack. He said to head down to the basement to an interior hallway, crouch down on the floor, tuck my head down between my knees as far as I could, and kiss my ass goodbye.

Normal basements are almost underground bunkers, a reinforced concrete lid tied into reinforced concrete walls and the basement is survivable from F5.
Most basements don't have reinforced concrete lids. They have a concrete floor and 4 concrete walls.

The basement ceiling is not concrete typically, and in an EF5 tornado it floats away into the air like a feather.

Survivable? Sure, with a probability distribution that I don't consider particularly favorable.

The only thing withstanding an F5 with the debris it carries is a bomb shelter.
I'd guess those exterior walls are 6-12" thick poured concrete, similar to this[1]. You can see in the 6th picture almost all of the missing wall is still there and intact, it's just lying flat on the ground. In the 12th picture you can see how thick they are compared to car wheels nearby.

I wonder what the insurance payout is for this? And the tax write-offs. Is it that simple, financially, just on a larger scale? Or is the scale too big for normal processes.
At Amazons scale the best thing might be to self insure. Remember insurance is paying a premium on assets to prevent an loss that you might not be able to re-raise capital for. At a large enough scale, there little point to paying the premium because that one warehouse of capital loss is a drop in the overall budget.
Yup, pretty sure they self-insure. Some big car rental companies also self-insure, because they are at the scale where they already have their own repair shops, and the premiums would be more expensive than just paying out the damages themselves (edit: and then they can sell their own insurance to renters!)
Pardon my ignorance, but what does it mean to self-insure? Does that just mean you have enough money on hand to cover the losses if it happens?
Yes, exactly. Actuaries are quite good at their jobs, which means the cumulative lifetime cost of insurance generally exceeds the (cost of covering a loss * the probability of that loss), so the only three good reasons to buy insurance are:

(1) you can't afford to cover the loss if it should occur (or maintaining/raising cash to cover it would be more expensive than the cost of insurance);

(2) the peace of mind from knowing you won't have to worry about raising cash to cover a loss (even if you could cover it) is worth the cost of insurance to you, even if it's a bad deal financially; or

(3) you know more than the insurance actuaries about your individual risk profile and have an edge (which is rare but can happen -- e.g., you know a specific product model is extraordinarily likely to fail and buy a cheap extended warranty for it).

The first is the best and primary reason to buy insurance, the other two are corner cases.

Is there any legal/procedural aspect to self-insuring, or is it just a placeholder for saying "we'll eat the costs" ?
I think it’s generally a phrase only used when it is a conscious decision or analysis for an area that generally already has insurance policys commonly written. Eg fire insurance for buildings and contents.
It’s possible to file for an exception to auto liability insurance by proving that you can cover any liability up to and including the state minimum for liability insurance coverage.
Generally, I would think there's paperwork/procedure/approvals required whenever the insurance protects more than just you.

Auto liability insurance is an example because it protects other drivers. Another example might be homeowner's insurance, which (if you have a loan) protects the lender too because the house is collateral.

Insurance does not remove liability from you personally. If you cause damage with your car, you are liable for it whether you are insured or not. The insurance is a private contract between you and the insurer where you basically agree to pay them a monthly amount and they agree to cover any losses you may be liable for (up to some pre-agreed limit). But the liability is not theirs, it is yours, and if the damages exceed your coverage limit, you are responsible for the difference.
There will be a salvage company to carry away anything worthwhile, possibly paying Amazon pennies per pound. Some of the salvage will end up at salvage bid yards or flea markets.
> Some of the salvage will end up at salvage bid yards or flea markets.

Or back on amazon, under the different name

Was there a severe storm warning in effect at the time? If so, what actions did Amazon take to reduce the exposure to this risk?

Did Amazon have effective storm shelters on site?

Did Amazon warn folks with enough time to reach shelters?

My suspicions here are that Amazon again prioritized profit ahead of safety. But the people who pay the price are the individual workers.

My heart goes out to all the families who lost loved ones or who are dealing with the anxiety of not knowing if they have.

It's just across the river from my hometown; the entire Metro St. Louis area had a few tornado sirens last night, as a wall of warnings swept across our region.

It seems like the worst tornado was this one that ripped through the warehouse (other pictures show some trees that had foliage stripped); you don't mess around with a tornado warning. It can drop pretty much anywhere along a storm front, or even sometimes in the middle or tail end of a front, especially when all the atmospheric conditions aligned like they did yesterday.

There was a much larger storm that seemed to have a 200 mi or so path through Arkansas, Missouri, Kansas and I think Ohio(?) last night. Some of these storms are still getting severe warnings this morning!

When I was a kid, a "Tornado Warning" meant that a tornado had been spotted and was something you took pretty seriously. There was another advisory called a "Tornado Watch" that meant conditions were favorable for tornados to develop.

Now, it seems that every semi-heavy thunderstorm comes with a "Tornado Warning" based on radar returns and other metrics. They happen so often it's hard to get too worked up about them. Another case of boy who cried wolf.

Your understanding is incorrect.

A WARNING means a funnel has been sighted or detected (e.g., by weather radar).

A WATCH means tornadic conditions are highly favourable.

From NOAA:

What is the difference between a Tornado WATCH and a Tornado WARNING?

A Tornado WATCH is issued by the NOAA Storm Prediction Center meteorologists who watch the weather 24/7 across the entire U.S. for weather conditions that are favorable for tornadoes and severe weather. A watch can cover parts of a state or several states. Watch and prepare for severe weather and stay tuned to NOAA Weather Radio to know when warnings are issued.

A Tornado WARNING is issued by your local NOAA National Weather Service Forecast Office meteorologists who watch the weather 24/7 over a designated area. This means a tornado has been reported by spotters or indicated by radar and there is a serious threat to life and property to those in the path of the tornado. A tornado warning indicates that you should ACT NOW to find safe shelter! A warning can cover parts of counties or several counties in the path of danger.

https://www.nssl.noaa.gov/education/svrwx101/tornadoes/

It's quite likely that either detection (and so sightings) has improved, or that tornados are now more prevalent in actuality. There's good evidence for both.

Edited for clarity:

A WARNING means a funnel has been sighted or detected (e.g., by weather radar).

A WATCH means tornadic conditions are highly favourable.

Gah! Thanks.

Fortunately, inside the edit window for once, I've updated my comment.

(Original repeated "warning" for both definitions in the part I'd written out rather than copied from NOAA.)

For those unfamiliar with the US Midwest and Edwardsville... here is a map of where the tornado hit. Looks like 2 swaths of destruction:

https://www.nytimes.com/interactive/2021/12/11/us/tornado-ma...

I know it's paywall'd, but I couldn't find any any other media outlet with a simple damage map like this.

Why is Amazon on Hacker News? It's just some dumb online store.
Why is this on Hacker News? It’s obviously a delivery station, not any kind of data center based on the trucks that were inside the facility in the video.
At least one of the people who died inside the facility was a 29 years old maintenance worker. I do not know how predictable tornadoes such as this are, but I won't be surprised if these deaths could have been prevented.

Source: https://twitter.com/AmeliaMtv/status/1469634726558412800

There is very little reason for anyone in that building dying! So sad!
Beside the tornado's direct hit?
No.

Buildings in Tornado-prone areas must be built with tornado shelters. Those are rooms within the building that are designed to withstand both a hit from a tornado, and the debris.

To be clear, the entire building does not need to be a tornado shelter. Just enough space within the building to hold its occupants.

(comment deleted)
The problem is that in the prediction of such extreme weather, in the middle of a really strong storm, this people should be told to get the fuck off, go home and take care of their families for a few hours instead to become martyrs of packaging. Why they were risking their lives working at night in a notoriously unsafe type of building, with a warning of tornado hitting the area?

This was the wrong decision also for Amazon. Taking at least the bare minimum reasonable measures to protect their employees would have saved the company a lot of money and lawyers time. Nobody could have stopped the warehouse destruction in any case but the recovering would have been much more simple and much faster.

Tornados can be predicted in broad terms but are highly variable on the ground.

Weather forecasts can usually identify that the conditions favorable for tornados are happening. That is announced as a Tornado Watch. If someone sees a tornado, they will issue a Tornado Warning, usually for the whole county. They will sound sirens if available. People are urged to take shelter, ideally underground. Otherwise they are told to shelter in the most substantial part of a building. Many people do take shelter but others decide to tough it out.

Tornados are relatively small compared to hurricanes and earthquakes but they are very intense within a few hundred foot wide area where they tear everything apart and blow it around with 300mph winds doing more destruction with that debris. They move in erratic directions and can pickup and hop around. There can be multiple tornados at one time.

Any one person is not a great risk of harm but anyone in the path of the tornado is at great risk. People living in the area have been through tornado warnings before without harm. This can lead to people assuming that they will be fine and not taking precautions. Chances are they are right but if they are wrong… it goes very wrong.

> Tornados can be predicted in broad terms

There are occasions where tornados can be predicted accurately with radar data, yet with only about a 4 minute lead time. The hook echo has been recognized for decades with recognition and detection further refined with Next Gen Doppler radar.[1] But not all tornadic storms display a hook echo and not all hook echoes produce tornadoes.

[1] https://en.wikipedia.org/wiki/Hook_echo

This is accurate. Particularly the “alarm fatigue”.

I’ve lived in the Midwest my whole life. I’ve heard many tornado sirens, been through many watches and warnings, and never once actually been close to a tornado that did any damage.

A few months ago I was woken in the middle of the night by my wife who heard sirens. I was groggy, and before I was convinced to get out of bed, the sirens stopped. This has happened dozens of times in my life, and felt entirely routine - there was no panic. A few minutes later my phone gave an emergency alert announcing a Tornado Watch. I decided it was time to move to the basement, so I went downstairs and set up candles and blankets, and then began the process of gently waking my 3 young children in an attempt to move them without terrifying them.

As I moved the last of them, I glanced at a clock and saw it was 11:53. We moved to the basement and all was quiet. It seemed like another false alarm.

The next morning I discovered that the tornado hit two blocks away from me, and leveled entire street’s worth of houses. Radar confirmed the tornado passed through my neighborhood at 11:50. If I had been two blocks south, at least me and my son would be dead. Potentially more of us.

Alarm fatigue is real, but don’t let it happen with tornado sirens. They come quick and hit hard.

While I can really *relate and understand how a "alarm fatigue" can build up, especially when you have to choose between sleep and taking shelter. However, I'm guessing that since these workers were currently at work, at an Amazon facility, have the reputation of being infamous for monitoring and clocking workers, these alarm fatigue considerations would not apply in the same way.

What might apply creating similar alarm fatigue effect, and this is really just me guessing based on Amazon facilities reputation, is the incentive (or its lack thereof) Amazon may provide for workers to evacuate vs continue their work.

* I have never experienced tornado alarm, but have experienced multiple rockets alarms, some of which, I've (foolishly) decided to ignore in favor of getting another hour of sleep.

When you hear a tornado warning, the advice is to shelter in place in the most structurally sound part of the building. Given that half of the building collapsed, there may not have been a safe place. Running away from tornadoes is not recommended, and you can't evacuate in advance of a storm because the region that tornados may hit is too large. Do you think there was a problem with how the building was built?

Here's an article with photos for anyone who doesn't want to watch the video: https://fox2now.com/news/illinois/photos-tornado-destroys-ed...

> Do you think there was a problem with how the building was built?

It is quite impractical to build a large building that will withstand a tornado. The fact that the building was cut in half and the contents largely removed is not terribly surprising.

Buildings like this (including big box stores, large grocery stores, office buildings, etc.) typically have designated tornado shelter areas. These should be on the lowest floor (below ground level is the best) with small rooms. The walls are generally made of cinder blocks or something sturdier. If you are in a building like this, need a tornado shelter, and don't know where it is look for the restrooms. When you get there you will likely find a sign that indicates it is the tornado shelter.

That defintely seems best, especially if underground any, but the footage shows a lot of shredded solid brick walls (footage from the Kentucky one, not the Illinois):

https://www.youtube.com/watch?v=zZMAmxP5cgs

Cinder-block with metal reinforcement is a level beyond brick though.

It's hard to build most buildings to handle a big tornado. https://en.wikipedia.org/wiki/Mercy_Hospital_Joplin is a concrete hospital that took a direct hit, the building is standing but it took very large amounts of damage and that's a beefy expensive building.

Was at my friends house in texas a month ago who had a storm shelter in the garage, it's a 1/4" steel box that is anchored to the ground and has the GPS coordinates etched on the inside since if it does it's job there may not be anything around but GPS to tell you where it is.

Wait, I'm not sure how having the GPS coordinates etched helps anything. What do they get used for?
I would guess if you call for help you can tell potential rescuers those coordinates.
Calling for help.

If your plat and neighbourhood have been scrubbed by the FSM's Own Geographic Erasor Pencil, there's not going to be much by way of landmarks to guide responders. Street sights, structures, and even kerbside markings will be gone.

GPS coordinates tend not to be strongly affected by severe wind events.

This is probably a good idea, though navigation like Google Maps would still work without streets or signs and bring you to the address.
This presumes that the occupants of the shelter know the address, that rescuers have cellular access (towers and other infrastructure may be down), or that the person(s) calling for help are the residents or usual occupants of the structure.

Survivors or those requesting help might not be adults or residents. They might be children, visitors, or strangers seeking shelter (particularly in the case of a business or commercial address). They might be volunteers searching for survivors. Contact might be over radio if phone service is down. GPS operates directly via satellite, so is independent of and terrestrial infrastructure.

The operating assumption of a disaster is that previous assumptions of normality are violated. Responses which remove assumptions of available serivces, or restore a bare minimal functional level of service, or which protect against likely disruptions, tend to be those that are most useful.

GPS is based on

Navigation using an address also works without cellular otherwise Garmin and TomTom devices wouldn’t exist.

I think an address is much easier to understand for a child.

Using an uncommon for most people method of location identifier brings problems of its own. Sure Lat/Long is familiar to us, but I’d guess the average person is unfamiliar.

Like I said, I like the idea but it doesn’t come without its own problems and addresses aren’t as useless in this scenario as implied.

Fair points. I'd still register GPS as more generally useful and usable.
your assuming they dont have both. people dont memorize their gps coords and theyre not easily findable with a phone. redundancy, defense in depth.
If the box flies away, you know where to bring it back to. And if it stays put, you can use it to calibrate gps satellites. Lol.
If you read the whole article, the building was demolished afterwards due to be structurally unsound.
Adverse-event construction codes are generally intended to provide survivability for occupants, not continued use of the structure itself.

You'll find that this is the case for, e.g., earthquake construction codes in seismicly-active regions.

Structures can be rebuilt. Humans are a more challenging rehabilitation challenge.

Though the Joplin facility was demolished, and five patients died, those were due to loss of power, and not from tornadic winds or debris themselves.

The building performed as intended, even under a direct strike.

"It is quite impractical to build a large building that will withstand a tornado"

It's also quite obvious there's a need for a shelter in areas where tornadoes are likely to form. So obvious in fact it's impossible to plead ignorance of that need, so the only other possible reason they didn't is carelessness because they could not have cared less if employees lives were at risk.

A large warehouse is pretty much built as a thin steel shell that would be expected to fail in more or less this manner in a tornado. However, there is usually an interior building within the warehouse that is built much more strongly (probably cinder-block masonry) that should withstand a tornado strike much more securely. That interior building would contain the warehouse offices, the bathrooms, etc., and it doesn't appear to be in the collapsed portion of the warehouse.
At least for Amazon warehouses that are not in tornado areas, warehouse workers are instructed by the managers to go to the center of the warehouse building during extreme weather events.

I do not know for sure if that same procedure would have applied to DLI4. But my feeling is that unless the state of Illinois, Madison County, or the city of Edwardsville have a specific regulation requiring such buildings to have tornado shelters, then there was no such shelter at DLI4, and workers were instructed to assemble in the center of the building.

Internal office sections of large Amazon fulfillment centers are off-limits to non-managers, and unauthorized entry is prevented thru the use of door badge scanners, which will not unlock the door unless the badge owner has sufficient permissions.

I can't imagine what an awful, dehumanizing, and absolutely terrifying experience it was.

Warehouses (any big-box building really) are among the worst places to be in a tornado. Maybe such buildings in tornado-prone areas should have storm cellars or reinforced "safe rooms" for shelter.
The time to ensure a structure has a safe shelter, or shelters, is before the wind-storm appears.
Interesting logistics problem, I wonder how good Amazon is about re-routing deliveries from other warehouses if a local one goes down? This is bad time of the year to be losing a distribution center.
And is it a good time of the year to die inside an amazon warehouse? I am sure 99% of people waiting for their deliveries with any kind of human compassion will understand the situation.
Wait, what country do you live in? Can I move there? I feel like most Americans don't view the human component of any of their transactions anymore, and have relegated nearly everything to out of sight, out of mind.
You got me... Canada ;)
While you bring up an interesting question, it's important to note that people died in that building. Perhaps some compassion is in order.

To answer your question though, unless the item someone ordered is unique and only stored in that warehouse, they will probably just mark the warehouse as down and the system will simply route around it and increase delivery estimates for the people who were served by that warehouse. They will probably redeploy the surviving trucks to nearby warehouses to handle the load.

I'll be honest: I'm not sure what the appropriate way to show compassion is here if it's not the purpose of the comment. Does every person commenting on something adjacent to the situation need to display compassion in this (still unknown) way?

Asking seriously. I want those complete strangers to not be in situations where they could die, and I want no one to die the same way in the future because someone did an engineering and made it safer. But they are people I don't/didn't know. Anything I could think of to say would feel as useless as "thoughts and prayers."

Not ask the question. Or at least acknowledge that people died before asking the question.
Was anyone under the illusion no one died when the tornado reduced half the building to scrap? I'm still not sure what the purpose is. If someone actually affected or connected to someone affected comes here and shares, that's different. Otherwise, it's not clear who it's for. "Performative" is overused by jerks who think everyone is as cynical and calculating as they are, but this seems to be a rare case where it actually applies. I don't see the purpose in this action you suggest. It seems like you went off on /u/voidfunc for no good reason.
> While you bring up an interesting question, it's important to note that people died in that building. Perhaps some compassion is in order.

I don't know why I need to provide a token "thoughts and prayers" just because my question is related to some tragedy. Everything has become so absolutely performative these days.

Yes, I am sorry this happened to some people. But I guess I'm an asshole because I didn't write some meaningless consolatory words in a comment on a tech forum before having the audacity to ask a legitimate logistics question.

Thanks for the answer, but please skip the condescension next time.

> I don't know why I need to provide a token "thoughts and prayers" just because my question is related to some tragedy. Everything has become so absolutely performative these days.

You could instead not post.

Timing is everything. There is a time to discuss those sort of things; this is not it.

> You could instead not post.

As far as I can tell my question is in line with the guidelines of the site and the submission itself doesn't provide any clarity about what the discourse of this thread is supposed to be about. It is quite open-ended.

> Timing is everything. There is a time to discuss those sort of things; this is not it.

Since you seem to know what time that will be, when is it?

To show you care about the humans that died. It's not performative. It's called being part of a society. Society prefers members who show compassion to others, and it's an important part of being a social creature.

For all you know, he could have just donated to the victims' gofundme after running a candlelit vigil, but here you are.

Feel free to express how upset you are, but please don't demand that we somehow express our feelings in a way that you deem sufficient.

This is a great example of why I'm really starting to hate the internet. You can't express any opinion these days without a few paragraphs with your life story explaining why you're allowed to have such an opinion. (For example having to be Jewish to say anything critical about Israel)
Similarly, since 2016, the obligatory "I hate Trump but" [discussion of why a Trump proposal/initiative may not be a horrible idea]
I voted for Biden but [semi conservative opinion].
This is a ludicrous expectation from a casual online discussion. voidfunc has no obligation to signal their compassion or lack of compassion, nor is society any worse off for the lack of that information in this context.

I’m with you.

Imagine everyone at Amazon directly involved in the operational disaster recovering effort having to preface everything they say and write with “thoughts and prays” before getting on with fixing issues.

We’re well aware people have died, and many more will have their lives impacted.

I’m an infrastructure and steel construction guy, I’m here to get shit done. If you need consoling you’ll find me quite abrasive as you’re probably in my way.

Friends, family, mental healthcare professionals, and religious practitioners are probably better at that than I.

I understand the concern about tornados, but living in the Midwest I gotta be honest I have zero concerns. Tornados are rare and might only be 50-200ft wide.

I’m much more concerned about general high winds. I live in a neighborhood amongst the fields and we regularly get 50-70 mph sustained winds with 70-90 mph gusts. We get these storms 2-4 times a year. Last night we had 40 mph winds with 55mph gusts.

To put it in perspective I’ve watched my neighbors fence blow apart and slam cars and neighbors windows/walls. Watched large play sets roll down the street, etc. our HOA had to put in rules about using iron / aluminum fences for this reason.

A couple years ago we had a thunderstorm & snow storm with high winds and temperatures were just right so everything built up a nice 1-2 inches of ice so power went out. Again way worse than tornadoes.

Hail also sucks
One of my old bosses bought a Subaru, she said the night she brought it come they had a massive hailstorm and when she filed an insurance claim they ended up totaling the car.

I guess the only silver lining is there are plenty of "salvage title" cars out here that are salvage just because of hail. Great for anyone that needs a car and doesn't care about dents.

If you get enough of them hail dings, they act like golfball dents and improve the aerodynamics: i buy cars with 'em for the better mileage.
And if you don't mind the appearance, it's a great way to buy a new or nearly-new car for cheap.
> everything built up a nice 1-2 inches of ice so power went out. Again way worse than tornadoes.

Somewhere around 100 people died just last night in these tornados. I think your couple inches of ice and power outage and fences in cars is not so bad compared to these tornados last night.

In terms of destructiveness, yes the tornados are worse. But OP is saying that in terms of frequency*destructiveness*area, high winds are more impactful to his life.
Also in the Midwest, had those winds last night. The wind knocked down two fence sections in between our backyard and the neighbor's backyard this morning. I didn't notice and let the dogs out and they got to explore the neighbors back yard for almost 15 minutes before I realized I hadn't seen them for a while.

Our section of the fence used to have issues also, but we spent an afternoon recently reinforcing the weak sections, and it held up just fine last night. If that had gone down though, they'd get to run directly into a prairie and anywhere in town, so I feel pretty lucky it was just part of the fence with my neighbor.

One of the two dogs did run away as a puppy (slipped out of a harness to escape going into the vet's office) and it took us four days to find and retrieve him, so I have firsthand experience and I definitely do not want to go through that process again, hopefully ever.

Yes, a given funnel cloud has a limited destruction band, but even that can be considerable. Note that the largest storms ("wedge tornados) have recorded funnel diameters in excess of 1 mile in diameter* (1.6 km for the rest of the world).

Additionally, once tornadic conditions are encountered, the risk itself is present over a large area, and people across 100s or 1,000s of square miles (that's rougly 260 -- 2,600 km^2) may be cautioned to take cover, affected by other strong winds, by windblown debris, and/or local or regional damage caused by the storms themselves. High winds sufficient to be damaging can exist well outside the vortex, the condensation funnel does not indicate the limit of tornadic winds, and the entire storm may be rain-wrapped, preventing visual observation.

It's a bit like being in a crowd whilst a gunman is actively shooting. The damage cross-section of any one round is small. The net effect on an aware crowd is large. The potential for damage itself changes behaviour considerably and has a marked psychological impact.

Wind damage increases with the square of the speed, and gusts are not sustained winds. The damage caused by a 500 MPH tornado field experienced for five several minutes is thousands of times greater than a few seconds of 50 mph gust, and that gust alone could topple a tree. The tornado will pick up the tree and use it to wipe your house from the Earth, with earnest effort and taking its time in doing that.

I get what you are saying, but long lived, highly destructive tornados like this one are downright terrifying.

Initial reports are that this tornado was three-quarters of a mile wide and traveled more than two hundred miles. That’s 150 square miles of near total devastation.

Even god hates Amazon .
I live in Nashville (moved from San Francisco in 2018) and this is the second Tornado scare I’ve had. The first in March of 2020 did significant damage in my last neighborhood of Germantown. The weather here in Tennessee still amazes and frankly scares me a bit. I’m just not used to it coming from California. Thankfully this time no real damage to my home or West side neighborhood.
Non-Fox, alternate source with drone footage, for those with a preference: https://www.youtube.com/watch?v=ROXs0F7gcc4

EDIT: Oops, wrong tornado (same day, different state).

https://www.youtube.com/watch?v=wsBzadyNWRY has a view of the Tornado from a local nearby, however.

Doesn't it seem like the cars in that (horrible) path of destruction survived better than the buildings?

This is the tornado that hit Kentucky not Edwardsville Illinois.
As far as I know Fox TV stations have no connection to the Fox with the cable news channel aside from being part of the same company in the past.

edit: https://www.mediamatters.org/fox-news/fox-affiliates-we-are-...

It’s reasonable for people with center-right, centrist, or left-leaning politics to distrust Fox affiliates. Some of them are in fact still owned by the same company as Fox News.

TV network affiliates can be either independently owned or owned & operated by the network. Disney did not acquire either the Fox TV network or the Fox TV O&O stations in the recent Fox studio sale to Disney, likely because Disney already owns the ABC TV network and strategic ABC affiliates.

tfw you want to avoid Fox so you accidentally post fake news. lol
I think you are grossly and uncharitably misrepresenting my comment by calling it "fake news" when I clearly pointed out my mistake and posted a correction inline with "EDIT" as soon as I was made aware. I don't think your response is an appropriate one in the spirit of Hacker News and I think you should reconsider this style of response.
slow clap

Good for you for turning a video about a tornado disaster into political commentary about the channel that aired the video. Shoot the messenger, divert from the topic of OP and virtue signal a bit. How charitable.

Are tornadoes a common occurrence in December? We don't get them where I'm from and I can't remember hearing about anything like this before.

My heart goes out to the families of those involved. This would be devastating at the best of times.

Historically, tornado season is from March through June, but, they can happen any day of the year.
No, tornadoes are definitely very rare in December, when it tends to be too cold for them to form. Continental US has been experiencing a very unusual heat-wave across the board though, and it has been causing havoc in normal weather patterns.
>No, tornadoes are definitely very rare in December, when it tends to be too cold for them to form.

I would not go so far as to say 'Very rare.' Even before we started seeing more major impact to our climate due to global warming, winter tornado outbreaks were roughly ~10% of all tornado outbreaks. https://www.spc.noaa.gov/publications/galway/winter.pdf

Spring and fall are definitely the most active seasons for tornados but they occur often enough year round that I think that, at least for the US, you can't say tornados are rarer than 'uncommon' for any time of year.

Not only did it hit an Amazon warehouse, it traveled 200 miles across 4 states in 4 hours, which is a record.

https://www.nbcnews.com/news/weather/quad-state-tornado-cros...

Edit: Yes, this is the same tornado: https://meaww.com/tornado-warning-amazon-warehouse-edwardsvi...

Edit 2: Hmm. Maybe not. Looks like I was wrong initially, and the fact this tornado hit the same night as an Amazon warehouse got leveled by another tornado is just the world's shittiest coincidence.

It's not uncommon for a severe storm system like this to produce multiple tornados. The "quad-state tornado" was farther to the south, cutting across the bootheel of Missouri, while the one that hit the Amazon warehouse was more north, near St. Louis.

Mentions of "tornado sirens" in these comments are triggering bad memories from my childhood in the Midwest. The house I grew up in had a tornado siren on our property, probably about 100 feet from my bedroom window. It was so f--king loud!!! And it felt like it last forever. Ugh!
Amazon is going to get sued hardcore, guaranteed. The issue is that nobody had to die. Even kids’ summer camps in tornado prone zones have this figured out. The summer camp I went to had 2 rooms in the camp’s gym that were formal tornado shelters. The gym, with these tornado shelter rooms, were built in 2001. The entire camp (300+ people) could fit in these rooms. Everyone could technically sleep in there too, but obviously they would split us up into boys/girls rooms and the counselors would still be watching us the whole time.

The 2 rooms themselves were basically a 12” enclosure (including the ceilings). There were also concrete pillars in the room to reinforce the structure. During normal times we used them for various activities. But, at least during a couple of summers, we had to evacuate (from the cabins or wherever) there. The program staff (people in charge of the camp) were always monitoring the meteorological radar 24/7. This was in North Texas, which is tornado alley. The camp was an hour north of the Dallas/Ft. Worth metroplex.

Amazon warehouses are Tilt-Up Construction. Basically 4-to-6-inch thick cast concrete panels on a grid on metal tubes as joists. Support pillars with basic trusses, and a roof tying it together.

You lose a ton of stability once that roof is gone. You lose a truss or a few pillars, and I'd imagine it came down like a house of concrete cards very, very quickly after the first wall section fell.

It has no chance against a tornado direct hit. You need a dedicated shelter structure for that.

You know what else is tilt-up? Most big box stores. Not sure why Amazon is being singled out here as I’m sure this building complied with all local building codes.
Strangely, tornados are largely a phenomenon a of the USA. Canada (the worlds second biggest country), has about 100 tornadoes per year putting it in second place; the US has 1200. See [1].

The most powerful tornados are the terrifying F5 category ones. The US has had 59 of those. Throughout the rest of the world, no other country has had more than two. See [2].

More precisely, most of these F5 tornadoes have happened in just a few states, Iowa, Texas, Oklahoma, and Kansas have had six each, and Alabama has had seven. See [3].
