Rain Arrives Early Monday, More on the Way

The system is expected to move in around midday Monday with the heaviest precipitation expected to occur over Los Angeles County

Residents are bracing for another winter storm system that forecasters say will move through Los Angeles Monday through Tuesday, bringing more rain, snow, hail, and possible flooding to the region.

The stongest wave of the system is expected to move in around midday Monday with the heaviest precipitation expected to occur over Los Angeles County, the National Weather Service said.

Up to 13 inches of snow could fall in the mountains with snow levels in some areas as low as 3000 feet. A winter storm watch is in effect above 5000 feet in Los Angeles County.

Heavy rain and some hail is expected over parts of Eastern Ventura County along with isolated thunderstorms, the NWS said.

Rainfall amounts could range between one quarter and three quarters of an inch across many coastal and valley areas and between three quarters of an inch and one and three quarters inches across the mountains, the NWS said.

Monday's rains are worrying many home owners who are still cleaning up from the last round of storms.

In the San Gabriel Valley, debris from trees line the streets and damaged roofs are still covered in tarps.

More than 434,000 customer accounts -- representing businesses, schools or residences -- were blacked out in the Southern California Edison service territory, and it took the utility more than a week to restore full service.

The California Public Utilities Commission has opened an investigation into why so many poles fell, and why it took so long for Edison to restore service.

With the damage estimated at nearly $75 million, Gov. Jerry Brown declared a state of emergency for 15 cities in Los Angeles County and the city of Rancho Cucamonga. The declaration will allow cities to apply for Federal funds to help with the cleanup of roads and infrastructure.

City officials said it could be several weeks before debris from wind-damaged areas could be cleared from city drainage systems and urged residents to beware of the increased risk of flooding.

Some urban areas could see flooded roadways and commuters on Monday should allow extra time to reach their destination.

Drivers along interstate 5 near the grapevine should be cautious and prepare for winter-like conditions, the NWS said.
