A flash flood warning has been issued for parts of Cook County, including the city of Chicago.

According to the National Weather Service, the warning covers east-central Cook County, including the city, until 11:45 p.m. Tuesday.

Numerous neighborhoods, including the Loop, Near West Side, Near South Side, Bridgeport and numerous others, are impacted by the warning.

The NBC 5 Storm Team warns that rain is falling at a rate of approximately six inches per hour in the affected areas, with the slow-moving storm overwhelming drainage systems and low-lying areas.

The National Weather Service sent an alert just after 10 p.m. warning residents “not to attempt to travel” unless they were fleeing flood waters, and warned of a “dangerous and life-threatening” situation.

Heavy rain is falling across much of the city on Tuesday night, with forecasters warning of “rapid-onset flooding” in the hardest-hit areas.

According to the National Weather Service, one trained weather spotter reported more than five inches of rain in a 90-minute span just west of the United Center in Chicago. There have also been multiple reports of water rescues in the area.
