In Chicago, the Chicago River surged with the rainfall, flooding onto the Riverwalk in some parts. The Metropolitan Water Reclamation District said Sunday night that they had reversed the flow of the river into Lake Michigan in response to the flooding.
Roadways across the area were also impacted, including Lower Wacker Drive, where water levels covered the road and fire officials had to rescue people stranded by the water.
The National Weather Service warned that flooded rivers and streams could continue to rise even after the rain moves out of the area.
More than 1,000 ComEd customers in Cook County were without power as of 9:38 p.m., according to the utility. DuPage, Kendall and Kankakee counties had more than 100 customers without power Sunday night.
