Cook County’s Department of Emergency Management and Regional Security (EMRS) and the City of Chicago’s Office of Emergency Management and Communications (OEMC) are reviewing damage from the severe thunderstorms that occurred between June 10 and June 11, 2026; and asking that residents who have been impacted by these storms submit an initial damage assessment. Several municipalities in Cook County including Chicago experienced power outages, downed power lines, tree emergencies, debris, and localized roadway flooding and structural emergencies due to these storm systems. EMRS and OEMC are partnering with the Illinois Emergency Management Agency – Office of Homeland Security (IEMA-OHS) to compile additional information.
