Heavy rain is expected to lash Racine County overnight and into the morning commute, which could trigger flash flooding in low-lying areas.

According to meteorologists at WISN 12 News, the rain will arrive after midnight and get heaviest during the morning rush. Rainfall totals could come to three inches in some areas.

The National Weather Service in Sullivan has issued a flash flood watch until 1 p.m. Wednesday.

“Heavy rainfall rates of 1 to 2 inches per hour is possible at times after midnight through Wednesday morning,” the alert reads. “Anyone with travel plans overnight into Wednesday morning will want to stay alert to the latest weather conditions as roads may be washed out or have moving water over them.”

Drivers are also urged to use caution when out and about because visibility is expected to be low during the worst of the rain.
