What happened
Officials across Southern California are preparing for significant ocean swells and coastal flooding driven by Hurricane Polo. High tides, peaking around 7 feet on Monday and Tuesday, are running nearly a foot above normal astronomical levels due to El Niño conditions, according to the National Weather Service. In Long Beach, officials closed Peninsula beaches and began reinforcing bulkheads and boardwalks.
