Areas Affected
The flooding warning encompasses communities including Chicago, Cicero, Bolingbrook, Oak Lawn, Berwyn, Downers Grove, Woodridge, and Midway Airport. Additional neighborhoods under alert include Chicago Lawn, South Lawndale, Englewood, Bridgeport, Roseland, and South Shore, along with areas like Burbank, Brookfield, Palos Hills, Hinsdale, Lemont, and La Grange.
Local law enforcement has reported standing water and slow-moving conditions, especially in creeks, streams, and underpasses vulnerable to overflow.
Driving Hazards
NWS officials cautioned that poor drainage in urban settings could exacerbate the flooding situation, causing roads and streets to remain inundated. Residents are advised to avoid driving through affected areas, as water depth and debris could create hazardous conditions.
According to radar data released by the agency, up to 2 inches of rain had already fallen when the alert was issued.
Urgent Safety Messages
“A Flash Flood Warning means rapid-onset flooding is imminent or may already be occurring. Persons along creeks, drainage ditches, and other waterways should take immediate precautions to protect life and property,” the NWS Chicago stated on X, formerly known as Twitter.
The warning includes key infrastructure points such as Midway Airport, while neighborhoods including Justice, Summit, Burr Ridge, Ashburn, Brighton Park, New City, Auburn Gresham, and Hyde Park remain under alert.
