California’s first full week of winter opens with rain tapping rooftops and wind rattling signs across the Bay Area. Conditions look manageable now, but a sharper edge arrives as a powerful storm system tightens its grip heading toward Christmas Eve.
According to the National Weather Service, a High Wind Watch is in effect from Tuesday evening through early Wednesday morning for much of the San Francisco Bay Area, Central Coast, and surrounding valleys. South winds of 20 to 30 mph are expected, with gusts potentially reaching 60 mph in exposed areas.
Rain continues through today across San Francisco, keeping roads wet and visibility reduced at times. Highs hover near 59 degrees, while additional rounds of rain develop tonight and Tuesday. By Tuesday afternoon, winds strengthen noticeably, especially along the coast, higher terrain, and urban corridors lined with tall structures.
The most dangerous window opens Tuesday night into early Wednesday. Strong gusts combined with saturated soil raise the risk of downed trees, power outages, and blocked roadways. Travel could become hazardous for high-profile vehicles on routes like U.S. 101, I-280, and the Bay Bridge approaches. Residents should secure loose outdoor items and avoid parking near trees.
Rain remains steady Wednesday, with periods of heavy rainfall possible. Poor drainage areas may flood quickly, especially during peak rain bursts. Conditions may deteriorate fast after sunset Tuesday as wind and rain intensify together.
Christmas Day stays unsettled, with showers and lingering breezes keeping roads slick for holiday travelers. While temperatures remain mild, hazards persist due to wet ground and lingering debris.
More alerts may follow as the storm evolves. Traveling or commuting this week? What conditions are you seeing where you are?
