North Lake Shore Drive has been reopened after heavy rains caused flooding in the southbound lanes between North and Grand avenues Sunday night, officials said.
Police began receiving reports of flooding about 7:10 p.m., police News Affairs Officer Veejay Zala. By 10 p.m., the nearly constant rainfall subsided, leading authorities to reopen the lanes, said Officer Hector Alfaro, a police spokesman.
During the heaviest portions of the downpours, firefighters helped motorists whose vehicles were caught under flooded viaducts near LaSalle Street and Lake Shore Drive, said Chicago Fire Department spokesman Kevin MacGregor.
“We are helping people out of the cars,’’ said MacGregor.
Meanwhile, in the West Side's Lawndale neighborhood near Roosevelt Road and California Avenue, at least two cars had the same problem.
“There are a couple of cars stuck and tow trucks are helping pull them out,’’ he said.
No one was reported injured, MacGregor said.
The downpours also led Chicago Transit Authority officials to reroute three bus routes that use the Drive -- 151, 146 and 147 -- as well as three others because of flooded viaducts, said spokeswoman Lambrini Lukidis.
The heavy rain caused some damage at some ComEd substations, leaving 2,000 customers without power. By 10 p.m., 1,800 remained without power as crews worked into the night, ComEd spokeswoman Arlanna Johnson said.
A flash flood warning issued by the National Weather Service expired at 1:30 a.m., though a dense fog advisory was issued for the collar counties and southern Wisconsin until 8 a.m., according to their website.
While final rain total numbers weren't expected until later today, only .57 inches of rainfall had fallen at O'Hare International Airport, according to preliminary totals by weather spotters. By contrast, 3.66 inches had fallen at Midway, according weather service meterologist Matt Friedlein.
Slow moving thunderstorms have produced very heavy rainfall and radar estimates that between one and two inches of rain has fallen, according to the site.
The fog is expected to move out of the area by late morning, Friedlein said.
