SAN FRANCISCO (AP) -- A cold storm system that promises up to one foot of snow in the Sierra Nevada and steady showers in the San Francisco Bay Area is moving into California.
Rain began falling in San Francisco on Monday afternoon, accompanied by thunder and lighting.
The National Weather Service expects the stormy weather to last through Wednesday. The Sierra Nevada could see 8 to 10 inches of snow with up to two feet in the higher peaks. Snow could fall at low elevations down to 2,500 feet.
Farther south, the Central Valley and Southern California could expect between a quarter and half of an inch. Forecasters warn drivers of strong winds Monday along Interstate 5 in the Central Valley.
Forecasters say another weaker system may hit California on late Thursday into Friday.
