Tropical Storm Marie has formed in the Pacific Ocean, with forecasters warning it could strengthen into a hurricane and affect Southern California over the upcoming Labor Day weekend. The National Weather Service is monitoring this tropical cyclone, which has a 90% chance of becoming more organized. Californians are advised to prepare for potential rain, high surf, and coastal flooding, particularly in areas like San Diego and Newport Beach, even though the storm is not expected to make landfall. Beach conditions are anticipated to be dangerous due to large waves. Residents are reminded to stay alert and not underestimate the storm, as it may still bring significant weather impacts despite not being a direct hit.
