A tornado that left a path of destruction, injuries, and death in Illinois Thursday has been classified as an EF-4.
The most destructive of several tornadoes that formed Thursday touched down about 80 miles west of Chicago. At least 2 people were killed and 20 others injured, Gov. Bruce Rauner said at a news conference Friday.
“This was a devastating storm,” Rauner said, according to WBBM‑TV.
The National Weather Service gave the tornado a preliminary EF-4 rating Friday, packing winds of up to 200 mph. That rating was based on the level of destruction the tornado caused, and will be confirmed after an aerial survey.
