Multiple tornadoes touched down Tuesday in central Will County prompting a brief Tornado Warning for the area.
The warning expired at 7:30 p.m.
"Head indoors immediately for safe shelter if you're in the path of this storm!" the National Weather Service tweeted.
The Chicago area could see some severe weather Tuesday as storms threaten to bring hail, damaging winds and the possibility of tornadoes.
The day is expected to be mostly cloudy, warm and humid with numerous showers and storms likely moving in during the late afternoon and evening.
Some of those storms could become strong to severe, with heavy rain, damaging winds between 60 and 70 mph and quarter-sized hail possible. An isolated tornado could form as well, especially in far western counties.
Part of the Chicago area sits under a slight risk for severe weather while others, particularly those along the lakefront, are in a marginal risk.
The storms are forecast to end overnight, though another chance for isolated showers and storms will return through Wednesday afternoon.
A Beach Hazards Alert is in effect through Tuesday afternoon for beaches in Lake County, Illinois. The alert warns of strong rip currents and wave heights of up to 5 feet.
A Flash Flood Watch was also issued for much of the Chicago area, in effect from 1 p.m. Tuesday through the evening hours. The watch warns that heavy rain ahead could prompt flash flooding for some locations following recent rainfall.
