Here's a cool graphic I found, that shows the paths of tornadoes from 1950-2006, here in the U.S.

Incredible.

Tornadoes are one of the most destructive forces in nature. Every year they threaten lives and property. The most powerful tornadoes can last several miles on the surface, be over a mile wide and have wind speeds exceeding 200 MPH (approx. 330 kmh). This graphic shows the tracks of every tornado in the contiguous United States from 1950-2006. The stronger tornadoes have the brighter lines. It is interesting to note that many of the tracks trend from southwest to northeast.
