CHICAGO (STMW) – Thunderstorms are expected to move into the Chicago area Sunday night, prompting a flood advisory.
The National Weather Service is predicting an 80 percent chance of thunderstorms before 1 a.m. Monday. New rainfall amounts between a quarter- and a half-inch are possible.
A flood advisory is in effect for portions of Cook, DuPage, Kane, Lake and McHenry counties, according to the weather service’s website.
Runoff from excessive rainfall will cause minor flooding of ditches, streams, creeks and low lying areas, the weather service said. The heavy rainfall will also result in ponding of water on roadways.
The weather service advises motorists not to drive in areas where water covers the road.
The rain is expected to stop Monday, when temperatures will approach 60 degrees, the weather service said. More rain is possible Monday night.
