San Francisco, CA – Moderate rainfall moved through the Bay Area over the past 24 hours, bringing the heaviest precipitation to the North Bay’s coastal ranges. According to the National Weather Service San Francisco Bay Area office, Mount Tamalpais recorded the highest total at 1.16 inches of rain as of Saturday afternoon.
Most other locations, particularly in the valleys, saw much lighter rainfall. “Many North Bay valleys only picked up around a tenth to a quarter inch,” the agency noted. Light showers were also reported in portions of the East Bay, Peninsula, and South Bay, generally ranging between 0.05 and 0.25 inches.
The rainfall map from the California Nevada River Forecast Center shows a clear gradient—coastal and hilltop regions collecting the most moisture while inland and southern zones remained relatively dry.
The showers come amid a mild start to the fall season for Northern California, offering a modest boost to soil moisture but no major flood or storm impacts. Meteorologists expect clearing conditions Sunday with partly cloudy skies and mild temperatures returning early next week.
