Hurricane Marie, currently a Category 2 storm with sustained winds of 100 mph, is generating hazardous weather conditions along the Southern California coast despite remaining hundreds of miles offshore. The hurricane, tracking north and west of the Baja California peninsula, is producing a strong south swell expected to generate 6- to 8-foot waves and dangerous rip currents throughout the Labor Day weekend.
The National Weather Service (NWS) forecasts light but widespread rainfall beginning early Sunday across Southern California. Most areas are expected to receive less than a quarter inch of rain, with higher-elevation regions such as the San Gabriel Mountains potentially seeing up to three-quarters of an inch. There is also a 5% to 15% chance of thunderstorms Sunday. Motorists are cautioned about slick road conditions, as accumulated oils on pavement could increase hazards despite the modest rainfall. The automobile association AAA advises drivers to increase following distances to maintain safety.
Coastal impacts are expected to be the most significant aspect of Marie’s influence in the region. The NWS has issued coastal flood and high surf advisories affecting Santa Catalina and Santa Barbara islands, Malibu, Los Angeles, and Ventura County. These warnings have been in effect since 6 a.m. Saturday and are set to continue until 11 p.m. Tuesday. Meteorologist Devin Black of the NWS emphasized that the safest option for beachgoers is to avoid entering the water due to the combination of large breaking waves and lifethreatening rip currents.
Surf heights along the Los Angeles and Ventura County shores are expected to reach between 5 and 8 feet, with Zuma Beach potentially experiencing even larger waves of 8 to 10 feet. Compounding the danger, high tides occurring in the evenings coincide with the southerly swell generated by the hurricane, increasing the risk of coastal flooding in low-lying areas and south-facing beaches such as Avalon, Long Beach, Point Mugu, and Malibu.
For those determined to visit the water, officials recommend swimming only near lifeguards, avoiding rocky areas and jetties, and following directions from local authorities. The NWS reiterated that these precautions are essential given the hazardous ocean conditions.
Climate scientist Daniel Swain of the University of California noted that Hurricane Marie is unlikely to be the last tropical system to affect California this season. He pointed to El Niño conditions, which typically increase hurricane activity in the eastern and central Pacific by warming ocean temperatures. Swain indicated that one or two more tropical storms could develop in September or October, potentially bringing similar impacts to the region in the coming months.
