(ABC) At least four tornadoes touched down in northern Illinois overnight as powerful storms swept across the upper Midwest.
The National Weather Service in Chicago said survey crews will investigate damage Thursday along three separate supercell paths. The number of confirmed tornadoes will likely increase, the weather service said. Officials also planned to request a survey of the damage by air, although a dense fog advisory was in effect for much of northern Illinois early Thursday.
The storm system produced dime-sized hail in some areas and its high winds snapped trees, blew roofs off buildings and downed power lines. The weather service reported winds from 80 mph to 100 mph in some parts of northern Indiana.
Heavy rain of 1.24 inches fell Wednesday evening at Chicago’s O’Hare International Airport, forcing delays of up to 90 minutes and 325 cancellations. Airlines at Midway International Airport cancelled about 70 flights, with 60-minute delays. Normal operations resumed Thursday morning at both airports.
In northern and central Indiana, nearly 30,000 homes and businesses were without power early Thursday morning.
Illinois Governor Bruce Rauner released this statement on the tornadoes that hit the state:
“Given the reports of tornado touchdowns across north-central Illinois last night, we are fortunate things are not worse and are thankful there were no fatalities. Diana and I are thinking of those who were injured or suffered property damage in the storms and send our prayers to you.
“I continue to receive regular updates from the Illinois Emergency Management Agency on damage assessment and cleanup today, and the Illinois State Police are on patrol offering assistance to local law enforcement. A special thanks to our first responders and volunteers who have been working tirelessly throughout the night to ensure the safety of our citizens.”
