Milwaukee, Wisconsin – Tornadoes are often associated with the central Plains, but they have touched down in every state, including Wisconsin, and residents here may have only minutes to act when an alert is issued.
According to the National Weather Service, tornadoes occur most frequently between the Rocky Mountains and west of the Appalachians, placing Wisconsin within an active Upper Midwest severe weather corridor. The state averages more than 20 confirmed tornadoes in many years, with activity typically peaking in late spring and early summer when warm, humid air collides with strong cold fronts across the Great Lakes.
A Tornado Watch means atmospheric conditions support severe thunderstorms capable of producing tornadoes. Watches often span wide portions of the state, from Milwaukee and Waukesha counties in southeast Wisconsin to Dane County near Madison and Brown County near Green Bay. When a watch is issued, families should review shelter plans, charge mobile devices and closely monitor updated alerts.
A Tornado Warning signals immediate danger. Meteorologists issue warnings when radar detects rotation or when a tornado is reported on the ground. If a warning is triggered in Milwaukee, Madison, Green Bay or Kenosha, move immediately to a basement or an interior room on the lowest floor, away from windows.
A Tornado Emergency is rare and reserved for confirmed, destructive tornadoes targeting populated areas. This alert signals catastrophic damage potential and life-threatening conditions.
Severe storms can intensify quickly across Wisconsin. Residents should keep wireless emergency alerts enabled and identify safe shelter locations before the next warning is issued.
