Strong thunderstorms moved across the Chicago area Wednesday night, leaving behind flooded roads, downed trees, power outages and damage stretching from the northwest suburbs into northwest Indiana.

Heavy rain and strong winds caused problems across much of the region, with damage reported in several communities, including Elgin, Streamwood, Chicago's West Beverly neighborhood and Griffith, Indiana.

In Bartlett, village officials said the storm knocked down numerous trees and power lines, especially on the north side of town. Widespread power outages were also reported.

Village crews, first responders, Public Works employees and ComEd crews are working to restore power and clear hazards. Cleanup efforts continued Thursday morning as crews assessed tree damage and worked to clear roads, sidewalks and public spaces.

The storm comes just about two weeks after an EF-1 tornado caused damage in Bartlett.

Illinois State Police said downed power lines near Interstate 94 between 115th and 130th streets were reported around 9 p.m. Wednesday. The lines were cleared around midnight, and there were no interstate closures Thursday morning, although the Illinois Department of Transportation may still be working in the area.

In Indiana, flooding and power outages were reported across Merrillville. Town officials urged drivers not to travel through flooded streets.

Shower facilities are also available on site."
