The National Weather Service has issued a flood watch for the entire Chicago area, with heavy rainfall rates possible as afternoon thunderstorms arrive.
According to the alert, rainfall rates could at times exceed 1-to-3 inches per hour at times, which could lead to flooding in low-lying areas, in urban locations, and in parts of the region that were hard hit by storms on Wednesday.
The National Weather Service says high humidity levels and warm temperatures could combine to create optimal conditions for heavy rain to fall, and the movement of the storms could bring them over the same areas multiple times and inundate creeks, streams and other areas.
The flood watch will remain in effect until 11 p.m., according to the National Weather Service.
Already on Thursday showers and thunderstorms have impacted the area, with a severe thunderstorm warning issued in parts of Will and Kankakee counties in Illinois, along with Lake and Newton counties in Indiana.
More storms are expected to develop as the afternoon moves along, with the entire area at a “moderate” risk of severe weather, one of the highest threat levels the Storm Prediction Center uses.
In addition to heavy rain, damaging wind gusts, large hail and tornadoes are all possible with storms that develop.
