Several inches of rain fell across the Chicago area overnight, particularly on the south and southwest sides, prompting road closures and Chicago Transit Authority delays.
Thursday evening rainfall totals included 3.12 inches of rain in Wheatfield, Indiana, 2.6 inches in Downer's Grove, 2.3 inches in Woodridge and 2.09 inches in Burnham. Three inches of rain fell at Midway Airport between 1 a.m. and 4 a.m. Friday, according to the National Weather Service. Another 1.47 inches fell at O’Hare during the same time.
By 5:30 a.m., conditions were improving on many facets of the transit network. Outbound lanes lanes of Interstate 290 -- the Eisenhower Expressway -- were reopened, as were two inbound lanes.
Service was also resuming on the CTA's Blue Line. Service was suspended about 90 minutes earlier between the Forest Park and Harlem stations due to flooding.
The westbound lanes of Interstate 90 -- the Kennedy Expressway -- were also closed at Kimball Avenue after a crash occurred about 3:30 a.m. that involved two semi trucks, police said. No injuries were reported. That incident was cleared after about three hours.
In the southwest suburbs, service on nine Pace bus routes was delayed because drivers were unable to reach a garage facility. Up-to-date service information was posted on PaceBus.com.
Flooding was particularly heavy in Burbank, with much of a residential neighborhood east of Narragansett Avenue, roughly between West 81st and West 85th streets, under water.
Officials said 200 homes were damaged in neighboring Oak Lawn.
The National Weather Service upgraded its initial flood advisory to the warning about 2:20 a.m. for Cook and DuPage counties, as well as parts of Lake County in northwest Indiana.
