Surf's up and the snow is falling here in the Bay Area.
Forecasters say another weather system moving into Northern California will be bringing cold temperatures and snow to some of the Bay Area mountain tops.
Both Mount Tam and Mount Hamilton were white Saturday morning.
The National Weather Service says the combination of temperatures around the freezing mark and precipitation being carried by the latest front could in turn drop light snow as low as 2,500 feet.
Some of the highest elevations especially in Monterey and San Benito counties could see between two to five inches of snow through Saturday night.
Along the coast, forecasters are warning people to be careful walking along area beaches. A high surf advisory is in effect from Sonoma County south to the Central California coast.
The National Weather Service says the surf in some areas could be as high as 22 feet.
In Southern California, forecasters are predicting rain and a chance of thunderstorms.
Here's NBC Bay Area meteorologist Rob Mayeda's forecast:
SATURDAY: A few areas of low clouds/drizzle are expected in the morning, by the afternoon skies will clear. Daytime highs will remain cool from the coast to inland locations: lower to mid 50s.
SUNDAY: A very cold start to the day expected with a few isolated 20s in the North Bay, otherwise most locations will bottom out in the 30s and 40s. A full day of sun is on the way, but temps will remain chilly with daytime highs only reaching the lower to middle 50s.
AHEAD: Another storm system will skirt along the California coastline Monday and Monday night. (New Year's Eve). This system will not move inland and expected to just bring a few areas of fog and drizzle, along the Coast. At this point, temps will be very chilly as well, with temps near midnight ranging from 36 - 44.
