More good info from NOAA
Click here to see a great page from NOAA about tornadoes, especially the global map showing where most tornadoes occur. The page contains a wealth of other information–see the charts on times of day and night that tornadoes have been reported, the explanation of “Tornado Alley” and “Dixie Alley,” and other helpful info for risk assessment activities.
Also check out a new link in the “Risk Assessment Info and Maps” section of the right side menu here on the Toolkit called “Weather Disasters,” for a newly added map indicating weather-related damage to states in the contiguous 48.
