The National Weather Service confirmed that at least six tornadoes touched down in four northern Illinois counties.
Based on video, photos and storm reports provided by storm spotters and storm chasers, the agency confirmed that tornadoes caused damage in Ogle, DeKalb, Kane and Lee counties, meteorologist Rafal Ogorek with the weather service’s Romeoville, Illinois, office said.
He said at least six tornadoes touched down in those four counties, but it’s likely additional tornadoes moved through the region in afternoon and evening on Aug. 9.
“There’s some uncertainty as to whether certain tornadoes tracked over a longer distance or whether they touched down in one spot, lifted and then touched down in another spot,” Ogorek said. “There were at least six tornadoes but that number will more than likely grow.”
The weather service staff will survey storm damage to determine how strong each tornado was and how long each was on the ground, he said. Storm damage appears largely confined to trees and crops, with some damage to barns and other structures, including at least one residence which lost its roof.
