A storm system moving across California is bringing cool, wet weather and snow to the Sierra Nevada mountains.
Chains or snow tires are required on most mountain highways around Lake Tahoe on the California-Nevada border as forecasters predict up to 7 inches of snow along the Sierra Nevada mountain pass, and up to 1 foot of snow at the highest peaks through Monday night.
The National Weather Service in Sacramento says a low-pressure system from the Gulf of Alaska is expected to drop up to an inch of rain in the low elevations.
Temperatures in the Bay Area and Central California are expected to dip to the 40s. Forecasters say rain is also anticipated along the Central Coast and in Southern California.
