Massive waves lashing the Southern California coastline have prompted beach and pier closures on Friday. While much of the focus was on Thursday's swells, including a dangerous rogue wave in Ventura, Orange County remains one of the epicenters for high surf and officials are urging residents and beachgoers to exercise extra caution. Lifeguards and first responders were out in force at Seal Beach early Friday morning. While the large waves might offer a spectacular view, officials were warning that those conditions could quickly turn for the worse. KTLA's Chris Wolfe and Vera Jimenez report on Dec. 29, 2023.
