Efforts underway to clear severe storm and tornado damage across Chicago area, Northwest Indiana

CHICAGO (CBS) — Severe storms brought heavy rain, high winds, and tornadoes across the Chicago area and Northwest Indiana Monday night. 

Efforts are underway to clear the storm damage and check on residents hit hardest by the severe conditions. 

The National Weather Service reported as many as 10 tornadoes on the ground during the evening. NWS officials are expected to provide an updated report later Tuesday. 

Data collected from 311 calls indicate that Chicago's West Side was hit hard. 

11 tornadoes confirmed Monday night

The National Weather Service on Tuesday said it was investigating 29 potential tornado tracks from the powerful and dangerous storm that hit the area on Sunday and Monday nights. Eleven tornadoes have been confirmed so far from the Monday night storms alone.

One of the tornadoes, an EF-1, hit the Near West Side of Chicago and far western portions of the Loop.

A tornado ranking at least EF-2 also hit near Channahon, and another EF-1 hit the Bristol and Oswego areas in Kendall County.

An at least EF-0 tornado caused damage in Justice and Bridgeview, and an EF-1 tornado struck in Crown Point, Indiana.

Six more tornadoes that spun up from Monday were confirmed Tuesday night—including an EF-0 from Crest Hill to Lockport, an EF-1 from Yorkville to Naperville, an EF-0 in Byron in Ogle County, an EF-0 in Davis Junction, an EF-0 from Sugar Grove to North Aurora, and an EF-1 in Chicago from Chicago Lawn to West Englewood.  

The amount of damage caused by each of these tornadoes was not immediately learned.     

ComEd outages continue

Over 200,000 ComEd customers woke up Tuesday morning to power outages caused by severe storm damage with flooding and downed trees. 

ComEd said about 80% of customers can expect their power to be restored by Wednesday afternoon. The remaining outages could be restored by Friday.   

ComEd crews and emergency management teams are working to clear roadways and residential areas.  

Oswego tornado destruction 

One of the confirmed tornadoes touched down in suburban Oswego. Heavy winds uprooted large trees, which toppled over onto homes and cars. One Oswego resident said she heard a crash that was "like a bomb." 

"I haven't called the insurance yet. I don't know where to start. This is the first time I've ever been through this," Carol Gillette said.  "I'm just happy we are all alive."

ComEd is working to restore power to the Oswego area after trees hit utility poles along Route 71. 

Downed power lines in Joliet

In suburban Joliet, the 1500 block of Jefferson Street is filled with debris and downed power lines. 

Police confirmed most of the businesses on the street and in the area are still without power.

ComEd crews responded to I-55 near Channahon due to downed power lines. 

There are two transmission towers down with high-voltage wires down across the highway. Two trucks, including a semi truck, are blocking lanes on the roadway.

The trucks appear to be intertwined with the wires across the highway. 

The roadway was shut down for safety purposes and to allow crews to clear the scene. 

In the same area, cars were left upside down due to the extremely high winds.
