Hundreds of ComEd crews have been restoring power to hundreds of thousands of people left without it following the fast-moving storm through northern Illinois.
On Sunday morning, about 67,000 Chicago-area homes and businesses were still without power, out of about 550,000 at the height of the damage Friday night, ComEd said.
About 22,000 customers are without power in the city and about 21,000 in the northern suburbs. In the southern suburbs, about 13,000 people are without power and in the western suburbs about 7,000 customers remain in the dark.
Some homes may still be in the dark come Sunday night, according to the Tribune. Spokesperson Arlana Johnson told the paper some of the most "significantly impacted" areas, like Des Plaines, should be without electricity Sunday night.
The height of the outage was around 8 p.m. Friday, when powerful wind and heavy rain blew through the area. That storm knocked out windows at Chicago's 110-story Willis Tower.
A second storm followed essentially the same path Friday evening. This time, the winds tore a roof off a building in Port Byron and threw it into nearby utility poles, causing two power transformers to topple onto a minivan.
In the city, first-responders treated a woman who was hit by glass near South Dearborn and West Washington streets, and another woman in Daley Plaza was injured when she was struck by a metal table.
Images from throughout the area showed snapped trees and limbs, some of them coming down on houses and cars. The city reported more than 2,975 "tree emergencies," where downed limbs were blocking roadways or resting on cars and homes.
Forty-four city crews armed with saws and cranes were quickly dispatched after the passage of the storms to clear the tree emergencies, reported Matt Smith with the city's Streets and Sanitation Department
North suburban Des Plaines was one of the hardest hit areas, and ComEd officials toured damaged facilities that included almost 30 high-voltage transmission poles “mangled” by high winds and other electric utility equipment, a ComEd release said.
The American Red Cross of Greater Chicago said it provided shelter, clothes and food to about 40 adults and 33 children effected by the storm.
Winds in excess of 70 mph with gusts up to 80 mph were recorded as the storm moved from Iowa. The Des Moines Register reported that winds there knocked a semi-truck off the road.
Chicago residents should call 311 to report damage.
