Nine tornadoes altogether touched down Monday night in northern Illinois, and one was stronger than officials originally determined.

The National Weather Service continues to investigate and evaluate damage and other information about the June 22 severe weather outbreak.

The tornado that caused considerable damage to Coal City, which is south of Chicago on the Grundy-Will county line, has been upgraded from an EF-2 to an EF-3. It was determined that top winds were around 160 miles per hour.
