A storm approaching from the northwest late Sunday evening, or early Monday, is expected to drop .5 to 1.75 inches of rain in Los Angeles County, according to the National Weather Service.
The forecast also calls for the possibility of minor flooding and gusty winds.
Recent burn areas could experience minor mud and debris flows, but rainfall rates are not expected to create concerns for older burn areas such as the Bobcat or Ranch 2 fires, according to the National Weather Service.
Thunderstorms are not expected during the storm, which is expected to move to the east by late Monday night.
The main front of the storm system — and the heaviest rain — will likely hit the Los Angeles area around noon Monday and move out of the area fairly quickly in the afternoon, the NWS said.
In the L.A. area, the forecast calls for a 40% chance of rain after midnight Sunday, increasing to a 70% chance by Monday afternoon, diminishing to 30% Monday night and becoming partly cloudy after midnight.
Upslope areas of southern Santa Barbara and Ventura counties could see 1 1/2 to 2 inches of rain, while other areas could get as little as a half-inch to an inch, forecasters said.
High temperatures Sunday are expected to be in the 60s at the beaches and in the low 70s inland, falling into 50s and 60s during the rain.
Dry and warmer conditions are expected during the rest of next week.
