The rain fell especially fast on Sunday, making it difficult for the ground to absorb it, Kluber said. Parts of the city saw rain fall as fast as 6 to 8 inches per hour, a rate more akin to tropical systems, he said.
“We get those rates up here, but it’s not as common,” he said.
The weather services issues flood watches for the Des Plaines River at Lincolnshire and at the city of Des Plaines, affecting areas in northern and central Cook County and parts of Lake County. At Lincolnshire, the river was at 10.2 feet as of Monday morning and was possibly headed to a flood stage of 12.5 feet, the National Weather Service reported.
A beach hazard was also issued for Lake Michigan at Porter and Lake counties in Indiana until 3 p.m. Monday, with high waves dangerous currents rendering swimming conditions potential life-threatening.
