I don't actually know when "tornado season" is, but i've got this vague inkling that it ain't now. Also no idea whether or not that should be read as any kind of augur. augur vs auger

Shelter is overrated I guess?

Sometimes it is. When I was in 4th grade in Texas, a tornado hit our school. Each classroom had a concrete ledge on the outside that was built with the promise that they were tornado proof. When the hit was imminent, the teachers had all the students get under the ledges. All of the ledges collapsed. Thankfully, no one died, and we got 1/2 day schooling at another school for the rest of the year, but, yeah, our shelter was overrated.

Unless the shelter is below ground, it is really all luck. Nothing man made can withstand this kind of concentrated force and winds. The debris field is what does it. Imagine wood, glass, trees, pieces of cars traveling at 120mph. This one was originally estimated as a 4, which is 180mph. There is a reason the 4 and 5’s are referred to as the Finger of God.

wouldn't a reinforced concrete structure hold up? I've never seen a 10 story apt build get a major make over by a tornado

Maybe, but bear in mind tornadoes tend to pick up shit like railroad cars and throw them around at 100+mph. Sometimes you just need to be underground.

Cities rarely get tornadoes. I am unsure why, but I would guess the buildings prevent the airflow necessary, who knows. Once the windows go, everything inside is outside and the building breaks down rather quickly given what the pressure does to the structure. To prevent that, most multi-level high-rises have building codes that mandate a certain amount of envelope protection. Windows are made to be as indestructible as possible with an inability to open them. They are made of multilayered plexi or some high strength plastic and glass combination. If the building envelope holds, there will be limited damage inside. You also rarely find an apartment building in the open Plains farming geography where most of the tornado belt resides.

You could also ask yourself, “Why do tornadoes always hit trailer parks?” Most people who live in a trailer cannot afford the building costs necessary to survive a tornado. Most houses are the same way. Commercial structures, well that is a different story.

@Grey_Beard Thanks. Money, money, money. That always seems to be the problem. My house survive hurricane Sandy but by the time it got to me it was already powering down.

But I have to give the guy who built it a lot of credit. All of the joists are 12" on center and her used 2x12s I think. I should measure them.

I doubt it would survive a direct hit by an F3 or 4 though. They're just vicious. Thankfully we're not far from the hills/mountains and there are a lot of ground obstructions to sap the energy.

I lived in a trailer park in TX long ago - Fort Hood IIRC. Hell's got nothing on TX

Of course, it's still some protection from slower, but still dangerous, flying debris.
