Authorities say at least seven people have been injured after severe storms that spawned at least one tornado tracked across northern Illinois.

High winds caused property damage and uprooted trees the Lee County community of Sublette on Monday night. Assistant Fire Chief Kevin Schultz says one person in Woodhaven Association, a private camping resort, was hospitalized with injuries that were serious but not life-threatening. Schultz says four other "walking wounded" were either treated on scene or refused treatment.

Damage to a mall in the Sterling area is extensive, with a roof reported to have been torn off a Sporting Goods store there.  Patrons tweeted messages of being trapped in the bathrooms while heavy rains pelted the area after the severe storms passed.

Further east in Grundy County, Emergency Management Director Joe Schroeder told WGN-TV early Tuesday that there were at least two injuries in Coal City, where the National Weather Service confirmed a tornado touched down. Authorities were still in search-and-rescue mode there early Tuesday morning, and a shelter was opened at a local high school.
