Kevin Donofrio, a meteorologist with the NWS' Chicago station, stated that the agency is observing a system of thunderstorms moving across the Mississippi River and advancing into Illinois.

According to Donofrio, the NWS has already received reports of wind gusts exceeding 60 miles per hour. These winds are anticipated to intensify as they approach the Chicago area, potentially reaching speeds of 70 to 80 miles per hour.

“The winds from the storm can be as strong as those produced by a tornado,” Donofrio stated.

Chicago tornado: Residents warned against potential power outages

People are advised to get ready for potential power outages and significant rainfall, as noted by Donofrio.

The storms are anticipated to arrive in Chicago during the late morning hours, approximately between 10 a.m. and 11 a.m., as reported by the National Weather Service.

Residents are also advised to take refuge in a basement or an interior room.

The storms have the potential to generate damaging winds exceeding 75 miles per hour, which may result in heavy rainfall and flooding concerns, as stated by the weather service.

At approximately 10:30 a.m., warning sirens were audible in various neighborhoods of Chicago. By 11:05 a.m., the most intense storms were situated in the southwest suburbs and northwest Indiana, while powerful storms traversing Chicago moved across Lake Michigan.
