Another winter storm is approaching California, where it's expected to bring freezing temperature, thunder, rain and snow as low as 1500 feet.

The National Weather Service said the cold weather system from the Gulf of Alaska was expected to reach the Bay Area late Monday and rain was forecast for Tuesday morning's commute.

Dark clouds started rolling across the Bay Area late Monday afternoon, and the menacing-looking sky obliterated the bright sunshine that many enjoyed the last few weeks.

"Oh, man it was wonderful. It was just great. I was grateful because I had a lot of outside work to do," said Joe Munch of Mendocino County.

An unusually wet November and December gave Bay Area water agencies a strong start to the rainy season.

At Lake Lagunitas in Fairfax, the water level is high enough that some came over of the spillway.

Marin County relies almost entirely on rainfall to replenish its water supply and despite the third driest January on record, Marin's reservoirs are at 98 percent of capacity.

East Bay Municipal Utilities District gets 90 percent of its water from Sierra sno pack and right now its reservoirs are at 81 percent of capacity.

In the South Bay, things are not looking so bright for the Santa Clara Valley Water District where the reservoirs are just 50 percent full.

The San Francisco Public Utilities Commission was unavailable on the President’s Day holiday to provide information on the Hetch Hetchy Reservoir which supplies the city and much of the peninsula.

But a United States Geological Survey website shows that as of Monday, Hetch Hetchy is still almost full.

 In Northern California, the heaviest snow was expected to drop Tuesday, bringing up to 10 inches above 3000 feet and 2 to 4 inches in the foothills above 2000 feet.

The storm was expected to move out of the state by Wednesday.
