Because the ground is frozen, heavy downpours ran off and caused flooding as the rain didn’t seep into the soil, ABC7 Chicago Meteorologist Larry Mowry said.

Officials are also keeping a close eye on Chicago-area rivers Saturday that may be at risk for flash flooding due to melting ice. There were near-record high temperatures this week across the area.

Water management officials said Friday was an overflow action day. The Metropolitan Water Reclamation District of Greater Chicago issued an alert Thursday asking people to delay showers and baths, flush less frequently and wait to run the dishwasher or washing machine.
