Tornadoes

[F.U.]

Those people had just 8-12 minutes warning of immediate danger. Ideally you'd think people were already hunkered down but apparently not since school was in session. Understandably, I guess life doesn't just stop when there's only a watch/warning.

8-12 minutes is pretty good warning. Not too long ago there was very little if any warning during tornados.

I'm somewhat stunned that the schools did not have underground tornado shelters. Maybe the geology of the area doesn't allow for it...

I heard that 8-12 minutes warning is good too but the area is rocky so there aren't a lot of basements.

I lived in OKC for 10 years and there are very few homes that have basements. Only 1 of my friends even had a storm shelter.
Coming from Iowa where we have very few tornados and almost every home has a basement it always puzzled me that there were so few basements right in the hear of tornado alley.
