Damaging storms flood flood expressways, viaducts and homes; thousands lose power in Chicago area

Severe storms ripped roof off Mt. Prospect apartment complex, downed trees in some areas Saturday night

CHICAGO (WLS) -- Damaging storms brought heavy rain that flooded roadways in Chicagoland overnight, and downpours continued in some areas on Sunday morning.

Many residents on the city's Southwest Side still haven't recovered from the flooding that hit there just three weeks ago.

FEMA was already in Gage Park Sunday surveying impact from July 25 flooding. The same questions remain: Who is going to pay for people's losses? And, what can be done to prevent this from continuing to happen?



Parts of the Chicago area saw 2 to 5 inches of rain on Saturday evening into the overnight hours, ABC7 Chicago meteorologists said.



The storms overnight quickly flooded several roadways, trapping drivers and knocking power out for thousands of people.

About 215,000 ComEd customers were affected by two rounds of storms Saturday evening and early Sunday, officials said at a Sunday afternoon press conference in Des Plaines.

As of 9:30 p.m., ComEd crews had restored power to 90% of the affected customers, officials said. ComEd expected to fully complete their power restoration process by Monday.

While flood waters receded later Sunday morning, some areas were still affected.



Cars became stranded in floodwaters at viaduct near West 47th Street and South Archer Avenue in Chicago's Archer Heights neighborhood on Sunday morning.

ABC7 was on the scene as some drivers tried to get through the floodwaters. At least four cars were stuck there at 5:30 a.m.

And a tow truck pulled one vehicle out of the water at another viaduct, near East 95th Street and South Cottage Grove Avenue. At least two cars were stuck there at 6:30 a.m., with people still inside.

Flooding is also impacting a viaduct near West 75th Street and South Western Avenue in Marquette Park.



Video captured some drive trying to brave floodwaters, with their vehicles apparently stalling out.

Other cars were seen driving on the sidewalk to get around the water.

Illinois State Police said earlier Sunday that the Stevenson Expressway was shut down in both directions at Pulaski because of the flooding. It has since reopened.

This all comes after storms blew through on Saturday, causing plenty of damage.



Saturday's storms hit the northwest suburbs the hardest, and the worst of the damage is in Mount Prospect and Des Plaines. That's where the storms ripped the roof off of an apartment building.

Rain and storms continued south of Interstate 88 on Sunday morning, but damaging wind was no longer a threat.

Storms hit the Chicago area's most southern counties between 7 a.m. and 8 a.m. Sunday, but the rest of the day is expected to be dry.

Up and down Chicago's Southwest Side on Sunday, residents were cleaning out their basements, again. Up to 5 inches of rain hitting the area overnight, leaving the water with nowhere else to go.



"We had our sectional furniture, Christmas decorations, things for our fur babies," Chicago Lawn resident Tameeca Dennie said. "Just everything is gone."

Chicago Lawn's Tameeca and Leslie Dennie enlisted the help of siblings and relatives to come over and help clean up the mess.

"It could have been worse," Leslie Dennie said. "So that's how I'm looking at it."

A little bit further north in Gage Park, it was much the same story as residents took stock of their losses now that the water has receded.

"Insurance told her that uh it was weather-related damages, so that's not covered by the insurance for some reason," Gage Park resident Carmen Aguilera said. "So she needed to get help somewhere else basically."

It wasn't just homes that were dealing with flooding. At St. Clare of Montefalco, parishioners arrived for Mass Sunday afternoon unaware that in the rear of the church, water was still being pumped out of the basement for the second time in three weeks.

"I fear for us, but more for the people of God. These poor people were just recovering," said Father Homero Sánchez with St. Clare of Montefalco. "I personally have the question what's the city doing about it. Right?"

Alderman Ray Lopez of the 15th Ward tried to answer that question as well Sunday, opening up his office for residents to report their damage. He says the problem is the existing system simply isn't equipped to handle several inches of rain in such a short period of time.

"We need to do some more proactive preventative measures," Ald. Lopez said. "Whether it's annual or quarterly cleaning of the sewers and catch basins or start looking at putting in some of these back flow valves when we are opening up the streets so that sewer and runoff does not flow back into the homes. That's 95% of what we're seeing out in the neighborhoods right now."

Chicago's department for Water Management said crews are working around the clock to address service requests. Adding that they are inspecting catch basins and sewers in the hardest hit areas to ensure they are functioning at capacity. In Gage Park, I'm Michelle Gallardo, ABC7Ewewitness News.

No rain was expected during day two of the Chicago Air & Water Show, and it was expected to stay dry for the Chicago Bears game.

However, storm chances will return to the area on Monday.

Areas west, north and southwest of the city are under a Level 1 threat for severe weather on Monday for potentially damaging winds.



Isolated storms are expected on Monday morning, but storms are more likely between 4 p.m. Monday and midnight Tuesday.

A few showers could linger on Tuesday morning before cooler weather arrives on Wednesday.
