Latest storms knock out power, down trees

August 2, 2011 (CHICAGO)

Winds moving at 60 to 70 miles per hour left some damage including downed trees and power outages.

Some severe thunderstorm warnings remained in effect late Tuesday night.

"Once again we have a severe line of storms moving through the area," said ABC7 Meteorologist Jerry Taft. "It's mainly wind and rain."

The storm blew trees onto power lines in north suburban Round Lake. Crews were on the scene cleaning up. At 18,000 people were without power in the north suburbs.

Not far away, ABC7 found some flooded parking lots.

In McHenry County, the storm brought strong winds and heavy rains. There were no reports of any serious damage in the area.

Time lapse video from the Willis Tower showed the storm moving through downtown Chicago.
