A category EF-1 tornado touched down in Frankfort, Illinois, during Friday afternoon's storms, according to the National Weather Service.
The tornado, which touched down at about 4:44 p.m., caused minor damage to about 10 homes, tearing off shingles and, in at least one case, blowing off doors.
Winds blew as fast as 90 miles per hour during the storm, and the tornado carved a path about 2.6 miles long with a width of about 50 yards, according to the National Weather Service. It stayed on the ground for about nine minutes.
Storms swept the Chicago area and parts of central Illinois in the afternoon and evening, causing power outages and flooding. In northeast Illinois, some roads were shut down due to the heavy rain, and some areas saw more than 2 inches per hour at times.
