California – Waves crash higher than usual along the shoreline this morning, while rain-slick streets reflect headlights across the Bay Area. Conditions feel unsettled early, and timing matters for anyone heading out near the coast or navigating urban roads before the weather calms.
According to the National Weather Service in San Francisco, a Flood Watch remains in effect through this evening for San Francisco, the Peninsula, East Bay, and South Bay. Bands of rain continue to move through the region, raising concerns for urban flooding, swollen creeks, and water collecting on roadways. A Beach Hazards Statement and High Surf Advisory also remain active, with large breaking waves and dangerous rip currents along the coast.
In San Francisco, showers and isolated thunderstorms could reduce visibility and slow traffic along U.S. 101 and I-80 approaches. Low-lying streets may briefly flood, especially near poor drainage areas. Along Ocean Beach and the Peninsula coastline, powerful surf may sweep across rocks and jetties without warning. Officials urge beachgoers to stay back from the water and avoid coastal trails during peak wave activity.
Rain tapers later today as cooler, drier air moves in. The weekend turns noticeably calmer, with brighter skies and cooler mornings settling in for the first full weekend of winter. That quieter stretch supports smoother holiday and end-of-year travel across Northern California.
Looking ahead, meteorologists are tracking a weak midweek system. By Wednesday, December 31, clouds may increase with a slight chance of showers around New Year’s Eve. Temperatures stay cool but above freezing, limiting winter precipitation concerns locally for now.
Plan extra time this morning, stay clear of hazardous surf zones, and keep an eye on changing conditions. Heading out this weekend or into New Year’s week? Let us know what you’re seeing where you live.
