CHICAGO (CBS) — Heavy rains moving through the Chicago area on the first day of summer could cause flooding problems, especially in low-lying areas and near streams and rivers.
The National Weather Service has issued a flood warning for Cook and DuPage counties.
Forecasters said the excessive runoff from Thursday’s heavy rain likely would cause flooding of small creeks and streams, urban areas, highways, streets, and underpasses.
A portion of the Chicago Pedway between City Hall and the Daley Center was closed around 9:15 a.m., while workers cleaned up a large puddle of water on the floor caused by the heavy rain.
Meantime, a flash flood watch also has been issued for most of northern Illinois through Friday morning, as several rounds of heavy rain and thunderstorms are expected Thursday morning and afternoon, and overnight into Friday.
Forecasters expect rain totals of 1.5 to 3 inches, with some areas getting as much as 4 inches of rain.
“These storms have the potential to produce localized flash flooding as many locations across these areas have received significant rainfall in the past week,” the National Weather Service said.
