Several areas in Southern California could have scattered showers throughout the day, but the potential for "damaging flooding" will not increase until the evening to overnight hours.

The storm is expected to dump 1 to 2 inches of rain along the coast and up to 4 inches in the valleys at rates that could cause problems. Some roads will be closed starting Wednesday.

Evacuation warnings and orders have been issued for Los Angeles communities near the Eaton, Palisades and Sunset fire burn zones ahead of the rain.
