Chicago, Illinois – Torrential rain is expected to push into Chicago overnight, bringing a heightened risk of flash flooding through early Friday. The most intense downpours may drop over two inches of rain per hour, threatening low-lying streets, viaducts, and underpasses across the city.
According to the National Weather Service in Chicago, the heaviest storms will impact areas north of Interstate 80, including much of the city. Urban flooding is likely, particularly on the South and West Sides, where poor drainage often leads to quick water buildup. Flooding is already underway in parts of northern Illinois and could spread into the metro area overnight.
Key trouble spots include the Dan Ryan, Eisenhower, and Kennedy expressways, where water tends to collect quickly during heavy rain. Residents in neighborhoods like Englewood, Austin, and Albany Park should stay alert for flooded basements and street closures.
City officials urge residents to avoid driving through water-covered roads and to secure items in basements or ground-level units. Make sure weather alerts are enabled on your phone — especially if you’re sleeping — as warnings may be issued during the night.
Flash flood concerns will persist into Friday morning, potentially disrupting the early commute across the city.
