Ahhh... Tornadoes. So destructive. So deadly. And to think, all of this can last only 3-25 minutes. I've never seen a tornado, but maybe you have, and you lived, because your reading this right now. So, a tornado can be catergorized based on size, and destruction. here are the five kinds:
F1-Moderate. Can turn your car upside down.
F2- Major. Can blow the roof off and turn mobile home over.
F3-Severe. Forest and farmlands flattened. Walls blown off.
F4-Devastating. Blows off all walls, if any left. And well built homes.
F5- THE MOTHER OF ALL TORNADOES!- if this passes near you, everything, gone. In a few minutes, your house, and yes, you also will be gone.
