LOS ANGELES (AP) - More rain and snow fell during the weekend in storm-battered California, making travel dangerous and prompting evacuation warnings over flooding concerns along a swollen river near Sacramento.

Bands of gusty thunderstorms started Saturday in the north and spread south, with yet another atmospheric river storm following close behind Sunday, the National Weather Service said.

Up to two inches of rain was predicted for the saturated Sacramento Valley, where residents of semi-rural Wilton and surrounding communities were warned to prepare to leave if the Cosumnes River continued to rise. The warning was downgraded from an evacuation order Sunday afternoon.

Gusts and up to 3 feet of snow were expected in the Sierra Nevada, where the weather service warned of hazardous driving conditions. Interstate 80, a key highway from the San Francisco Bay Area to Lake Tahoe ski resorts, reopened after being closed most of Saturday because of slick roads and snow.

The University of California Berkeley Central Sierra Snow Lab tweeted Sunday morning that it received 21.5 inches of snow in 24 hours. Its snowpack of about 10 feet was expected to grow several more feet by Monday.

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

The California Highway Patrol rescued three people whose car slid off a rain-slicked road and ended up teetering at the edge of a cliff in the Santa Cruz Mountains on Friday. The occupants of the car “were scared for their lives and were in disbelief” when they were pulled safely from the car as the vehicle’s front end hung precariously over the cliff’s edge, the highway patrol said in a statement.
