Chicago, Illinois – Flooded roadways stretched across much of the Chicago metropolitan area after heavy rain moved through the region, creating dangerous driving conditions from Joliet north to Evanston.
According to the National Weather Service in Chicago, a Flood Advisory remains in effect until 8:30 a.m. CST Friday for Cook, DuPage, and Will counties. The advisory follows up to 3 inches of rainfall that fell Thursday afternoon and evening, overwhelming drainage systems and causing rapid rises on creeks and streams.
While the heaviest rain has ended, standing water remains on multiple roads, particularly in urban and poor-drainage areas. Officials said roadway flooding is slowly improving, but high water is receding gradually, and some streets may remain impassable.
Communities reporting ongoing flooding concerns include Chicago, Joliet, Naperville, Evanston, Cicero, Skokie, Des Plaines, Bolingbrook, Orland Park, Tinley Park, Oak Lawn, Berwyn, Wheaton, Oak Park, Downers Grove, Glenview, Elmhurst, Lombard, Carol Stream, and areas near O’Hare International Airport.
The National Weather Service said several stream gauges showed rapid rises overnight, with creeks and streams still elevated. Although little to no additional rainfall is expected, lingering runoff may continue to affect low-lying areas and underpasses.
Drivers are urged to use extreme caution. Flooded roads can be difficult to detect, especially in low-light conditions, and water depth may be greater than it appears. Officials stress that most flood-related fatalities occur in vehicles.
Residents should avoid driving through flooded streets, watch for barricades, and allow extra travel time. Pedestrians are also advised to stay clear of swollen waterways and fast-moving water.
The Flood Advisory replaces earlier flash flood warnings issued during the height of the storm. Additional updates will be issued if conditions worsen or if water levels fail to recede as expected.
