On October 14, 2025, a powerful storm system brought heavy rainfall to the Bay Area, leading to widespread flooding and disruptions. In San Francisco, various streets experienced localized flooding as the city was soaked by downpours, with crews from the San Francisco Public Works department working to clear clogged storm drains.
The National Weather Service issued a flood advisory for San Francisco and surrounding counties, warning of minor flooding in low-lying and poor drainage areas. The San Francisco Fire Department responded to several reports of flooded streets and buildings, urging residents to stay home and drivers to avoid entering deep puddles.
Elsewhere in the Bay Area, the storm caused havoc on the freeways, with the California Highway Patrol reporting dozens of collisions, roadway flooding, and other hazards. A possible tornado also touched down near Pescadero in San Mateo County, and the National Weather Service will investigate the damage on Tuesday.
The most concerning situation was in Napa County, where the National Weather Service issued a flash flood warning for the area surrounding the Pickett Fire burn scar. Heavy rainfall and the potential for dangerous debris flows prompted authorities to warn residents and motorists to stay clear of the affected areas.
