Seriously, I Don't Like Tornadoes
What I don't understand is why county codes in areas prone to tornadoes, don't insist on implementing the Miami-Dade County building codes. Down here homes are built to withstand very high winds over 100mph. Roofs have straps that tie them into the walls. Walls themselves are almost always reinforced concrete block construction, and windows must be impact resistant. You can hit a hurricane window with a hockey puck traveling at 100mph, and it'll bounce right off. Back in the 1980's they relaxed some of the codes, and the result was the utter destruction of brand new homes by Hurricane Andrew. Older homes tended to fare better, so the counties in South Florida reinstated the codes, and beefed them up.
I know using the South Florida codes won't stop the damage from an F4 tornado, but it would mitigate it, offering the residents a chance to survive. Those balloon frame constructed homes of the prairies, just can't stand up to the force of a tornado.
