Storm blows out windows at 110-story Chicago tower

CHICAGO (AP) - A swift-moving storm carrying high winds and pelting rain knocked out windows at Chicago's 110-story Willis Tower.

Police on Friday roped off areas around the imposing black building long known as the Sears Tower. Chicago Battalion Chief Michael Gubricky says windows were blown out in a 29th-floor air conditioning mechanical room and a 25th-floor unoccupied office.

Glass was on the sidewalk, but no injuries were immediately reported near the tower. Authorities say a woman did receive minor injuries from flying glass at the downtown Daley Center blocks away.

Chicago fire officials say another person was seriously injured by a falling tree on the city's west side.

The National Weather Service says winds in excess of 70 mph were recorded as the storm whipped into Chicago.
