A tornado is a violently rotating column of air extending from a thunderstorm to the ground. In an average year, about 1,000 tornadoes are reported across the United States, resulting in 80 deaths and over 1,500 injuries, according to the National Oceanic and Atmospheric Administration. The most violent tornadoes are capable of tremendous destruction, with damage paths as wide as a mile and as long as 50 miles and wind speeds of 250 mph or more. Destruction of homes, crops, and utility infrastructure cost the U.S. hundreds of millions of dollars every year.
