Here’s where the most rain has fallen in the San Francisco Bay Area so far

LATEST Sept. 18, 10:57 pm The National Weather Service said it received reports of rocks and flooding on Highway 1 near Andrew Moleras State Park in Big Sur just before 11 pm on Sunday night. “Road conditions on HWY 1 could be hazardous during this period of moderate to heavy rain,” the weather service said in a tweet.

Sept. 18, 9:35 pm Parts of the San Francisco Bay Area reported nearly three inches of rain Sunday as intermittent showers, strong winds and isolated thunderstorms continue to move through the region.

The National Weather Service’s Oak Ridge station, located east of the small town of Annapolis in Sonoma County, has seen the most precipitation in the Bay Area so far, reporting 2.9 of rain, meteorologist Brooke Bingaman told SFGATE on Sunday evening. Nearby, the high elevation towns of Cazadero and Venado saw 2.75 inches and 2.66 inches of rain, respectively.

San Francisco has seen considerably less precipitation – just three tenths of an inch drizzled over downtown, but “a lot of people have been reporting brief, heavy downpours,” Bingaman said. “People haven’t seen rain like this in such a long time.”

Sunday was forecast to be the wettest day across the Bay Area, though total rainfall won’t come close to reaching record-breaking amounts. That’s because of a particularly strong storm that made its way through the region in 1959, resulting in more than two inches of rainfall in a single day.

“But that doesn’t mean this rain isn’t significant,” Bingaman said. “We have moist conditions that will mitigate fire risk and even though this isn’t a drought-busting storm, any little bit helps as we fight a multi-year drought.”

The wind advisory was issued for the region and will be in effect until 4 am Monday. Peak gusts ranged from 25 to 50 miles per hour in the San Francisco peninsula, 40 to 45 mph near Mount Tamalpais and 35 to 45 mph along the North Bay coastline, which may have contributed to some widespread power outages throughout the Bay Area, Bingaman said . On Sunday night, PG&E’s outage map reported disruptions in the Sunset District along the Great Highway and in the Marina District on Beach Street. However, the winds appear to be dying down.

“The brunt of the storm is really starting to move inland now,” Bingaman said. “If anything, they should continue at a gradual decreasing trend.”

Notably, a few lightning strikes touched down in Sonoma County on Sunday, and a slight chance of thunderstorms will be possible through Monday evening in the North and East Bay and possibly along the San Francisco peninsula, Bingaman said.

“It’ll be a situation where people need to stay alert,” she said. “If they hear thunder or see lightning, they should make sure they take shelter in a sturdy home or car and wait it out.”

Bingaman also advised that people take caution during their Monday morning commute.

“We’ve seen multiple reports of spinouts and collisions from the California Highway Patrol incidents page. The roads are wet and slick and people haven’t driven in the rain for a while. Remember to drive carefully.”
