The National Weather Service now believes that at least three tornadoes touched down across the Chicago area during a severe weather outbreak on Saturday, with straight-line winds also causing damage in Rockford.
According to officials, one of the three EF-0 tornadoes touched down in suburban Oak Brook, while the other two tornadoes both touched down in different parts of Boone County.
The first tornado touched down in Oak Brook near a Hilton Hotel and the Willow Crest Golf Club, according to officials. That twister, categorized as an EF-0 tornado on the Enhanced Fujita Scale, packed estimated peak wind speeds of 75 miles per hour, and reached a maximum width of 60 yards. The tornado was on the ground for approximately 1.9 miles, and while it was it snapped tree branches and caused the roof of an outbuilding at the golf course to collapse. It was on the ground for three minutes before lifting up.
