Southern California is experiencing rare September rain, coastal flooding, and dangerous surf conditions due to Hurricane Marie, which remains offshore. The storm is causing significant impacts, including high surf and hazardous rip currents at beaches throughout the region. Long Beach and Seal Beach have reported flooding as a result of the powerful surf, which also led to the closure of Malibu beaches due to lightning. Residents are advised to be cautious, as coastal flood advisories are in effect. Forecasts indicate continued rain, humidity, and the potential for additional showers over the Labor Day weekend, although experts clarify that a direct hurricane impact on California is unlikely.
