The large waves and periodic sets of up to 11 feet pose a significant risk to beachgoers in San Diego County, particularly at south and southwest-facing beaches. The NWS warns of life-threatening rip currents, which could endanger swimmers and surfers. This marks the third tropical system in three weeks to impact California's coastline, raising concerns about the cumulative effects of these weather events. Elevated sea surface temperatures, which reached 75.7°F (24.3°C) at Scripps Pier on Saturday, may further exacerbate the storm's impact.
