Tornadoes touched down in five counties outside of Chicago Monday night.
WLS-TV reports one hit Coal City, about 60 miles from Chicago, around 10 p.m.
"A lot of homes have been damaged, power lines are still down throughout the area, you can smell natural gas — so we've got some leaks all over as well," a WLS-TV reporter said.
Several subdivisions were directly hit, as well.
"If we just come over here, you can see how the roofs have been blown off these homes in the subdivision right over there," a WBBM reporter said.
Quite a bit of damage was also reported in the town of Sublette, where the Chicago Sun-Times reports one person was injured, but is now in stable condition at an area hospital.
WMAQ reports four other people were treated for injuries at a campground where the tornado struck.
Early Tuesday, Illinois Governor Bruce Rauner mobilized the State Emergency Operations Center to help first responders if needed.
