A flood watch remains in effect until late Tuesday night for the entire Chicago metro area as rain and possible thunderstorms move through the area, the National Weather Service is warning.

The Chicago area had seen an inch or two of rainfall by Tuesday morning, according to the weather service. More showers and thunderstorms were expected to drop another inch through the evening, with some areas seeing up to three more inches.

The rainfall, combined with melting snow and rapid runoff due to frozen ground, could flood low-lying areas and cause water levels to rise in rivers and ponds, the weather service said.

Minor flooding and standing water were reported on roads throughout the Chicago area, according to NWS meteorologist Stephen Rodriguez.

The left shoulder and left lane of the inbound Eisenhower Expressway were closed about noon near Cicero because of flooding caused by a collapsed sewer inside the CTA Blue Line, according to a statement from the Illinois Department of Transportation.
