The National Weather Service is warning that showers and thunderstorms could hit already saturated areas in Illinois and Indiana on Tuesday, leading to concerns of severe weather and flash flooding.

According to a hazardous weather outlook issued by the service, damaging winds of up to 60 miles per hour could occur as storms develop, with most of the showers and storms likely occurring in areas to the south and east of Interstate 55.

Flash flooding is also a serious concern, with a flash flood watch in effect for McHenry, DeKalb, Kane, DuPage, Cook, LaSalle, Kendall, Grundy, Will and Kankakee counties in Illinois, along with Lake County in Indiana.

Areas already hard-hit by showers and thunderstorms in recent days could see flash floods due to heavy downpours, according to forecast models.

A river flood warning also remains in effect for parts of the Illinois River in LaSalle County. Cook County and Lake County are also under a warning for the Little Calumet River, and Jasper County is under a river flood warning as the Kankakee River rises above its banks.

Some severe weather has already developed in the area, with a severe thunderstorm warning issued earlier in the day for Newton County in northwest Indiana.

That storm generated a wind gust of 62 miles per hour was detected at Kentland Airport just after 3:30 p.m., according to the NWS.

A severe thunderstorm warning was briefly issued for northeastern Kankakee County, but was canceled after approximately 20 minutes after the storm weakened below severe limits.
