LOS ANGELES>> Storm-battered California got more wind, rain and snow Saturday, raising flooding concerns, causing power outages and making travel dangerous.

Bands of rain with gusty winds started in the north and spread south, with more storms expected to follow into the early part of the week, the National Weather Service said.

More than 68,000 utility customers were without electricity Saturday morning, a number that was cut by more than half during the afternoon, according to poweroutage.us.

Flood warnings were issued for the region north of San Francisco Bay, including Marin, Napa, Sonoma and Mendocino counties.

To the south, warnings were posted for parts of counties including San Mateo and Santa Cruz, where the tiny community of Felton Grove along the San Lorenzo River was ordered evacuated. Residents of semirural southeastern Sacramento County were warned that overnight flooding was likely and to be ready to leave.

The swollen Salinas River swamped farmland in Monterey County, and to the east, flood warnings were in effect for Merced County in the agricultural Central Valley, where Gov. Gavin Newsom visited to take stock of storm problems.

Slick roads, snow and whiteout conditions plagued highways through the Sierra Nevada. The University of California’s central snow lab tweeted Saturday that it received 21.3 inches of snow in 24 hours and that its snowpack of about 10 feet was expected to grow several feet by Monday.

A backcountry avalanche warning was issued for the central Sierra, including the greater Lake Tahoe area.
