SAN FRANCISCO (CBS SF) — Northern Californians slogged through another day of wet and windy weather as the second storm of the weekend moved through the region on Sunday.
After a brief break in the foul weather Saturday evening, heavy rain and strong winds returned in force on Sunday.
People driving campers or hauling trailers were advised to stay off the Bay Bridge, the San Mateo Bridge and the Carquinez Bridge in Vallejo due to high winds.
The National Weather Service issued a flash flood warning for parts of Sonoma County, including the Petaluma area.
The warning came as Willow Brook, which flows through Petaluma, topped its banks Sunday morning, causing what Henderson described as “minor flooding.”
Sunday evening, Napa officials said the Napa River was expected to crest above flood stage north of Napa and near St. Helena but would probably stay within its bank inside Napa city limits. The city closed Veterans Memorial park, the Riverfront Promenade, Oxbow Preserve Park and Trancas Crossing Park until further notice.
In East Palo Alto, the rising waters of San Francisquito Creek caused
flooding on northbound U.S. Highway 101 just north of Embarcadero Road, officials said on Sunday night. Nearby West Bayshore Road was closed between Embarcadero and San Antonio roads, according to the CHP.
State Highway 84 was closed Sunday evening in two counties, according to Caltrans. In San Mateo County it was closed at La Honda due to
rocks and a downed power line in the road, and in Alameda County it was closed near Palomeres Road due to a large rock slide.
Earlier in the day, in San Francisco, several inches of water were reported in north and southbound lanes on U.S. Highway 101 near Cesar Chavez St., according to the CHP.
In Santa Rosa, several roadways were all or partially blocked by standing water or mud, according to the CHP.
Motorists were cautioned not to wade or drive through flooded areas.
On Interstate 80 through the Sierra, officials said chains were required on vehicles except four-wheel drives from the Placer County community of Gold Run to the Nevada state line.
Stormy weather complicated air travel at San Francisco International Airport.
As of 12:30 p.m. Sunday, 25 flights — nine departures and 16 arrivals — had been cancelled, SFO duty manager Lily Wang said.
Most other flights were running between 45 and 90 minutes behind schedule, she said.
Regional flights were most heavily impacted by cancellations and the delays were expected to worsen Sunday evening, Wang said.
Thousands of residents lost power as rain and wind pounded the region.
The majority of outages were reported in the North Bay, where 5,300 customers were without power in Marin, Sonoma and Napa counties as of 1:30 p.m., PG&E spokeswoman Jana Morris said.
In the East Bay, around 1,375 customers experienced outages, Morris said.
