Chicago, Illinois – Tornadoes are often associated with the central Plains, but they have touched down in every state, including Illinois, 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 Illinois in the heart of one of the nation’s most active severe weather corridors. The state averages dozens of confirmed tornadoes in many years, with peak activity in late spring and early summer when warm, humid air clashes with strong cold fronts across the Midwest.
A Tornado Watch means atmospheric conditions support severe thunderstorms capable of producing tornadoes. Watches often span wide portions of the state, from Cook and DuPage counties in the Chicago metro to Sangamon County near Springfield and Winnebago County near Rockford. 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 Chicago, Peoria, Champaign or the Metro East region near St. Louis, 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 Illinois. Residents should keep wireless emergency alerts enabled and identify safe shelter locations before the next warning is issued.
