Probability of Dying in a Tornado

Tornadoes kill an average of about 70 people per year in the United States, resulting in approximate lifetime odds of dying in a tornado of 1 in 60,000. The US experiences more tornadoes than any other country, with roughly 1,200 per year. Most of these occur in "Tornado Alley" stretching from Texas through the Great Plains.

The most dangerous tornadoes are rated EF4 and EF5, which have winds exceeding 166 mph and can level well-built homes. Mobile homes are particularly vulnerable, accounting for a disproportionate share of tornado deaths despite housing a smaller percentage of the population. Most tornado deaths result from flying debris.

The best protection during a tornado is to move to an interior room on the lowest floor of a sturdy building, away from windows. A basement provides the best shelter. Mobile home residents should identify a nearby sturdy building for shelter. NOAA weather radios and smartphone weather alerts provide critical advance warning. Storm shelters and safe rooms built to FEMA standards offer near-absolute protection.
