The high surf and coastal flood conditions are creating hazardous situations along the coast, including flooding in areas like Seal Beach. Rip currents and longshore currents pose dangers to swimmers, particularly those inexperienced. Elevated tides exceeding 7 feet are expected to increase the risk of coastal flooding. Inland, rising temperatures will bring moderate to major heat risks, especially in the Los Angeles basin. Beachgoers are advised to avoid water contact due to an ocean water quality rain advisory in effect until at least 2 p.m. Wednesday.
