Northern Illinois Flood Watch Issued: Up to 5 Inches of Rain Expected by Early Tuesday Morning

Chicago, IL – A Flood Watch is in effect for northern Illinois and northwest Indiana as heavy rain and thunderstorms are expected to drench the region through tonight, with the potential for flooding in more than a dozen counties, including Cook, DuPage, Kane, Lake, and Will. Urban areas and low-lying regions could see rapid flooding as rainfall totals reach up to 5 inches.

Flood Watch and Heavy Rainfall Predictions

According to the National Weather Service, rainfall rates of 2 to 4 inches per hour are possible, with some areas receiving more than 5 inches where storms repeatedly track. The ground is already saturated from recent rainfall, making the area particularly vulnerable to flooding, especially in Chicago, Rockford, Aurora, and Joliet.

Flooding Risks and Impact on Roadways

Low-lying roadways, underpasses, and areas with poor drainage are at the highest risk of flooding. In Cook and DuPage counties, officials warn of widespread street flooding, particularly during the evening commute. Additionally, northwest Indiana, including Gary and Valparaiso, could experience flash flooding as storms push east.

Safety Tips and Potential Disruptions

Residents are urged to avoid flooded roads and move vehicles to higher ground to prevent damage. Power outages and transit delays could also occur if the storms persist through the night.

The Flood Watch will remain in effect until late tonight, with additional advisories possible if rainfall totals continue to rise.
