At around 12 p.m., a clean up was underway in San Anselmo where the morning's intense rainfall caused minor flooding. Across Marin County, authorities have seen a few car spin-outs, collisions and some fallen trees.
The storm first impacted the North Bay Thursday morning, causing flooding on roadways and bringing gusty winds to the Marin Headlands of up to 50 miles per hour.
The rain hit San Francisco at around 7 a.m. and moved to the South Bay from 9 a.m. to noon, National Weather Service Meteorologist Roger Goss told KCBS Radio.
"We're expecting about a half inch to an inch for most urban areas across the region, up to about three inches in some of the coastal mountains, especially the Santa Cruz Mountains, but overall not expecting widespread flooding concerns," Goss said, calling the rain "beneficial."
Thursday night, temperatures are expected to drop — a cause for concern for weather officials. "It's going to turn very cold tonight and into Friday morning, so that’s going to be our main concern as the rain moves on out of the area and the winds begin to die off," Goss said. "We could see some widespread 20s up in the North Bay valleys, even some lower 30s in the interior portions of the East Bay, so it's going to be a cold one."
Flood advisories were issued in the morning for San Francisco, the South Bay into Santa Cruz and the East Bay.
More rain is forecast to come over the weekend, along with snowfall in the Sierra.
