The ongoing hurricane activity poses severe risks to Southern California's coastal communities. High tides, combined with strong waves and elevated sea levels, have caused significant erosion and flooding, damaging infrastructure and reshaping beaches. The region is also bracing for potential winter storms fueled by the strongest El Niño on record, which could exacerbate coastal erosion and lead to further damage. Experts warn that if these storms coincide with king tides, the impact on the coastline and infrastructure could be catastrophic.
