Scattered thunderstorms and heavy rain are set to impact Chicago and much of northern Illinois through late Wednesday night, bringing the risk of flooded roads, power outages, and hazardous conditions for thousands.
Timing and Impact of the Storms
According to the National Weather Service in Chicago, multiple rounds of storms will move across the region starting late Tuesday and continuing through Wednesday. The storms will bring periods of intense rainfall, with some areas receiving several inches of rain in short bursts. This could lead to flash flooding in low-lying areas, city streets, underpasses, and creeks. The severity of the weather is rated at a 2 out of 5, with flash flooding risk rated at 3 out of 4 for the area.
Areas Affected
Drivers in Cook, DuPage, Kane, and Lake counties should be prepared for sudden water over roadways, particularly during the morning and evening commutes. Local emergency management teams are advising residents to charge their phones and check flashlights in case of power outages. They also warn against driving through flooded roads, as conditions could deteriorate rapidly. Additionally, stronger storms could bring damaging winds, which may down tree limbs, and scattered lightning could disrupt outdoor plans.
Ongoing Threats and Safety Measures
The soaking rains will move eastward at speeds of 30–40 mph, with thunderstorms continuing to threaten the region through Wednesday night. More advisories may be issued if conditions worsen or flooding becomes more severe. It’s essential to stay updated with local weather alerts and to follow safety recommendations.
Prepare for Severe Weather
As thunderstorms continue to impact the region, residents and commuters are urged to take precautions. Stay informed, avoid driving through flooded roads, and make sure to have backup power sources in case of outages. Flash flooding remains a significant threat, so be cautious of rising water on roadways.
