The National Weather Service issued a flood advisory Friday for parts of five Bay Area counties, including Oakland, San Francisco and San Jose, after heavy rain caused flooding in areas with poor drainage. The advisory runs through 3 p.m. Pacific.
Forecasters said water was pooling in low spots and could cover roads. The weather service issued the advisory at 12:59 p.m. after members of the public reported heavy rain. It warned that street flooding was already happening or could develop shortly in parts of the affected area.
Where the advisory applies
The advisory covers part of Alameda County, central Contra Costa County, eastern San Francisco, northern San Mateo County and northwestern Santa Clara County. The weather service named Berkeley, Richmond, Fremont, Hayward, Daly City, San Mateo, Redwood City, Mountain View and Sunnyvale among the places where flooding could occur.
The advisory covers flooding from rain. Along the coast, a separate surf warning covers exposed Pacific beaches in the Bay Area and along Big Sur.
Before driving
Check Caltrans QuickMap for current state highway conditions and closures before leaving. On local streets, watch for water collecting in underpasses and other low spots. If water covers the road, the weather service advises turning around. Water can hide a washout or be deeper than it looks. Use another route if you come across a flooded road or a barricade.
