San Francisco Bay Area, CA – Drivers across parts of the Bay Area are waking up to dangerous visibility conditions this morning as a Dense Fog Advisory remains in effect, raising concerns for travel during early Sunday hours.
According to the National Weather Service San Francisco Bay Area/Monterey, dense fog has developed across the North Bay and East Bay interior valleys, reducing visibility to as low as one-quarter mile in some locations. The advisory remains in effect until 11 a.m. Sunday, with the most hazardous conditions expected during the early morning commute.
Weather officials warn that low visibility may make driving conditions hazardous. Motorists are urged to slow down, use low-beam headlights, and leave plenty of distance between vehicles when traveling through fog-prone areas.
The fog comes as the region approaches a potential shift in weather patterns. Forecasters note that the Bay Area has gone nearly three weeks without measurable rainfall, but that may change soon.
Updated precipitation outlooks show increasing rain chances beginning Tuesday and continuing through the end of the week, particularly across San Francisco, Oakland, San Mateo, San Rafael, Santa Rosa, Napa, and coastal communities. Some locations could see rain chances climb above 70 percent by Thursday and Friday, marking the most promising opportunity for widespread rainfall so far this month.
While no flooding concerns are currently expected, the return of rain could impact travel and outdoor plans later in the week, especially following prolonged dry conditions that can make roads slick when rain first begins.
For now, officials stress that fog remains the immediate concern, particularly in inland valleys and low-lying areas where visibility may fluctuate rapidly.
Residents are encouraged to monitor local forecasts, allow extra travel time this morning, and stay updated as rain chances increase across the Bay Area this week.
