Tornadoes

A tornado is a rotating column of air that extends from a thunderstorm to the ground. They can cause fatalities and devastate communities in a matter of seconds. Not all tornadoes may be visible at first, and they could occur at any time of day or night. Planning and practicing how and where you take shelter could save your life.

Wisconsin averages 23 tornadoes a year. Peak tornado season in Wisconsin is April to August, but they can occur any time of year.
