SAN FRANCISCO (BCN) — Mainly light amounts of rain are expected across the Bay Area Friday through Sunday, a National Weather Service meteorologist said.

Rain Friday morning will taper off by Friday afternoon, but could pick up again Saturday night into early Sunday, meteorologist Sierra Brune said.

A 75 percent chance of rain exists for Saturday night and early Sunday morning. For most areas, amounts will range from one-tenth to a half-inch with somewhat more possible in the North Bay and somewhat less in the South Bay.

Some roadway flooding has been reported by the California Highway Patrol. CHP officials reported 1 to 2 feet of water on the southbound on-ramp to U.S. Highway 101 from Van Ness Avenue in San Francisco.

But throughout the city there were no reports of any flooding, San Francisco Department of Public Works spokeswoman Rachel Gordon said.

“It’s pretty quiet,” Gordon said.

Residents in the city did report two large fallen tree branches, including one in the Mission District.

Neither branch caused any injuries or damage, Gordon said. City officials continue to offer 10 free sandbags to residents whose property is prone to flooding.

The sandbags can be picked up from 8 a.m. to 2 p.m. Friday and Saturday at the DPW operations yard at Marin and Kansas streets. Residents need to bring proof of address.

Few electric customers were without power Friday morning, but about 6,300 customers lost power in the Watsonville area at 7:17 a.m. because of weather-related issues. As of 9:30 a.m., only about 70 were still out, PG&E spokeswoman Mayra Tostado said.

The cause was a broken cross arm and a downed wire at 783 San Andreas Road in unincorporated Santa Cruz County, Tostado said.

That also caused an outage in the La Selva Beach area where 722 lost power. Electricity to all those customers had been restored as of 9:40 a.m.

Less than 75 customers were without power throughout the nine-county Bay Area as of 8 a.m., she said.

Because inclement weather can often lead to downed power lines, Tostado reminded residents who encounter downed lines to stay away from them and call 911.

Meanwhile, Yosemite National Park is closing roads due to major storms in the area.

The park has closed Tioga Road, which tops 9,000 feet, because driving conditions deteriorated Friday.

Glacier Point Road, which rises to 8,000 is set to close at 5 p.m. Saturday.

Both roads usually close for the winter months.
