The National Weather Service (NWS) San Francisco has issued multiple warnings for the Bay Area as a series of storms approach, promising to bring life-threatening conditions to the region. A High Surf Advisory is in effect until 4 PM Sunday for all Pacific Coast beaches, with a predicted large westerly swell causing breaking waves of 20 to 26 feet, and even higher at favored spots such as Mavericks. Due to the dangerous conditions, residents and visitors are cautioned against turning their backs on the ocean.
