Another powerful Pacific storm system reached California Monday,

Forecasters are expecting rain, wind and heavy mountain snow today and into Wednesday.

The cold storm was expected to push ashore last night in the north and spread over the state through Wednesday.

The National Weather Service warned that the winds could easily topple trees because the very wet winter has left soils saturated.

The system could drop several feet of snow in the upper elevations of Northern California's coastal mountains and the Sierra Nevada, making travel difficult.

Powerful storms since late December have blanketed the Sierra in a massive snowpack with a water content that is more than 220% of normal, according to the state Department of Water Resources.

The Mammoth Mountain ski resort in the Eastern Sierra said that with 667 inches (16.9 meters) of snow at its main lodge and more than 840 inches (21.3 meters) on its 11,053-fo0t summit, the resort was on the verge of breaking its record for snowiest season. That is 70 feet of snow.

When all is said and done, the National Weather Service anticipates as much as another inch of rain to fall on Manteca, Ripon, and Lathrop.

Sonora and Yosemite Valley could receive three inches of rain.

The forecast calls for up to 30 more inches of snow on Tioga Pass (Highway 120), 36 inches of more snow on Sonora Pass (Highway 108), and 48 inches of snow on Ebbetts Pass (Highway 4).

In Southern California's mountains, the storm could drop snow at elevations as low as 2,500 feet (762 meters) and possibly on foothills, forecasters said.
