Stormy Chicago

While we were tracking Hurricane Dean in the Gulf of Mexico, we here in Chicagoland had our own interesting weather for the past few days. Thursday August 23, 2007 was the worse.

Matter of fact the entire region from Iowa to Indiana to Illinois to Michigan suffered from severe storms.


NIU DeKalb Campus declared an emergency closure. In a statement the university stated;

"Due to potentially worsening flood conditions on our DeKalb campus, the university has declared an emergency closure and urges those personnel who are not designated as essential to emergency services to leave campus as soon as possible.

Only two bridges in DeKalb are currently passable, and with additional rain forecast, travel throughout the county is likely to grow increasingly difficult as the day goes on.Due to the status of this action as an emergency weather closure, personnel will not need to use leave time.The university*s regional centers in Rockford, Naperville and Hoffman Estates are not affected by this closure and remain open. Please use caution in traveling due to flooding road conditions."


Thursday was some of the worse weather Chicago has seen in years.

I was downtown during the height of the storm and clocked wind gusts at 63 MPH along N. Michigan Avenue, with wind driven rain where most trying to walk N. Michigan Avenue were doing so without much success. To say the least, umbrellas were useless.

Damage in my immediate area was limited to fallen trees around N. Michigan and Lakeshore Drive. Flooding was extensive along Lakeshore with beach access tunnels flooded. Ohio Street beach also flooded.
The lightning show was just fascinating as well as dangerous.

Here are just some of the other damage reports from the region.

310,000 powerless in Chicago area

The Associated Press
A fast-moving storm packing winds over 70 mph turned skies from day to night across a wide swath of the Chicago area Thursday, damaging homes and businesses, splitting trees and bringing planes and trains to a halt.

About 310,000 customers in northern Illinois were without power Thursday night, including 62,000 in Chicago, said ComEd spokesman Tom Stevens, who added that it could take days to restore power for some customers north of the city.

People who ventured out to survey the storm's aftermath dodged felled trees, downed power lines and other debris knocked about by high winds.

Chicago officials said the city's emergency center been called for nearly 1,300 "tree emergencies," which included uprooted and split trees and limbs blocking intersections.

Langford said trees in several areas of the city hit power lines and exploded transformers, setting utility poles on fire.

"This is not a storm that's isolated," said Chicago Fire Department spokesman Larry Langford. "This one hit the entire city north to south."

A roof collapsed at the dock area of an industrial building in the suburbs, injuring 40 people, authorities said. West Chicago Police Department spokesman Mike Uplegger said seven people were sent to hospitals and the rest refused treatment at the scene. None of the injuries was considered life threatening.

A large piece of metal scaffolding at Northwestern Memorial Hospital's Prentice Women's Hospital collapsed during the storm, and two people suffered minor injuries but refused treatment, Langford said. Also, the rear wall of a four-story building under construction on Chicago's North Side collapsed, but no injuries were reported, he said.

Officials warned residents to prepare for flooding, with one to two inches of rain drenching on an already waterlogged area.

"That's what we're worried about right now," said National Weather Service meteorologist Nathan Marsili. "It could turn out to be a pretty bad flooding situation for the area."

Elizabeth Schreiber, who works at a public relations firm in Chicago, was in a cab returning from a work lunch when she looked out the window and noticed a tree had smashed into her 1998 Toyota Camry.

The uprooted tree lay across two other vehicles and her car, completely crushing its roof.

"It looks crazy around here," she said while waiting for help. "It's really bad."

Matt Steinkraus, 29, of St. John, Ind. — in Chicago for his wedding on Saturday — was walking downtown with his fiancee and friends when the storm struck.

"As soon as it hit, we made a break for the nearest bar," he said. "We got drenched ... then we went into the bathroom, wrung out our shirts, ran them under the dryer."

About 500 flights were canceled at O'Hare International Airport Thursday evening and passengers should expect delays of more than 2 1/2 hours, according to Chicago Aviation Commissioner Nuria Fernandez. Delays at Midway Airport averaged 1 1/2 to 2 hours.

Judy Pardonnet, a spokeswoman with Metra commuter rail system, said there were delays throughout the system because of debris on the tracks and malfunctioning signals.

"It's going to be a slow commute home for us," she said.

The National Weather Service would not be able to confirm tornado touchdowns until Friday, meteorologist Gino Izzi said. He said 74 mph wind gusts were recorded in Midlothian and near Wrigley Field.

As the storms rolled through, officials feared flash flooding. Some areas of northern Illinois could see 3-5 inches of rain — of particular concern because the ground is so saturated with water from recent rains, Izzi said.

"If that happens, you could be talking very serious flooding," Izzi said.

In Fox Lake in far-northern Illinois, the Fox River flooded some homes while other residents stacked sandbags to protect their houses, said Ami McEwan, assistant administrator for Lake County.

"Most of them are sandbagging and keeping it at bay," she said.

In downtown Gurnee, just west of Waukegan, workers were stacking sandbags to protect an elementary school from the Des Plaines River, she said. School hadn't yet started for the fall, so no students were affected.

A foot of water stood over roads in the Rochelle area, about 20 miles west of De Kalb, and the Des Plaines River was more than 3 feet above flood stage north of Waukegan, according to the weather service.

An afternoon storm that included high winds uprooted trees and damaged homes and knocked out power across Galesburg, about 40 miles northwest of Peoria, according weather service and local authorities. The storm also blew the windows out of a church in nearby Toulon, and knocked out power lines across Stark County, just north of Peoria.

Trees and limbs were down all over town, but no one was hurt by the fast-moving storm, Galesburg Fire Department Battalion Chief Brad Stevenson said.

"It was such a broad area, and it came up so quick and was gone so quick," he said.

State Flooding & Severe Weather Reports

Region V Illinois

Severe storms moved through northeast Illinois (Chicago area) in the afternoon on August 23, 2007, causing power outages, downed trees, and roof damage to several buildings.

One fatality has been confirmed in Knox County due to a falling tree. No other injuries have been reported to the State.

Power outages have been reported in Cook County, Knox, LaSalle and Warren Counties.

At 3:30 pm CDT, August 23, 2007 the Exelon Nuclear Power Plant at Braidwood had one unit manually shut down by the operators due to loss of vacuum. The loss of vacuum was caused by the automatic shut down of 2 circulating water pumps when the pumps experienced fluctuations. This is standard protocol with this type of mechanical failure and the reactor was shut down without incident.

Braidwood Unit 1 is still at power and both reactors at the Braidwood site are stable. This is not a classifiable incident under NRC regulations and poses no danger to the public or the workers at the station. The US NRC has been notified. The IEMA resident inspector is on-site.

The majority of damages reported have been minor.

The State EOC is being staffed, but has not been activated. The State has requested Illinois State Patrol, Illinois Department of Transportation, Illinois Department of Natural Resources, External Affairs and a Legislative Liaison to report to the EOC. There have been no requests for State Assistance. Continue reading...
