Keep in mind, you can be a "safe" distance from a tornado, but the rotating winds around it are still easily strong enough to kill you with debris. There are some unreal videos on youtube showing cars in a parking lot getting blasted up into the air with absolutely NO warning.


Never heard of that. I had only heard of it going up to F5.

After the storm there was talk of adding F6, but the powers that be just call it the enhanced scale. EF0 thru EF5.

Look at it this way:

When a tornado pulls an interstate highway up (including the road base), it is BAD NEWS!

I am sure you can find more info from NOAA/NWS and The University of Oklahoma.
