The developing El Niño poses significant risks to California's coastal communities and infrastructure. Higher tides and storm surges could accelerate beach erosion, threatening properties and ecosystems along the shoreline. Inland areas may also face flooding due to heavy rainfall, increasing the risk of damage to homes, roads, and other infrastructure. The ongoing hazardous ocean conditions have already claimed lives, highlighting the immediate dangers posed by strong swells and unpredictable surf. Residents and visitors to coastal areas should exercise caution, particularly near eroding beaches and during high tide events.
