That happened in the 1997 Jarrell, TX F5 also. That sucker dug stuff out of the ground (including roads!) over a 7 mile by 1/2 mile area. An in-ground shelter had better have a steel door and strong hinges & lock to stay intact through that monster.

Fortunately they're rare, and tornadoes don't have the water problem that is the bad news in a hurricane.
