The high tides associated with El Niño pose a significant risk to coastal areas, particularly in Huntington Beach. Residents may experience flooding in low-lying areas, which could lead to property damage and potential disruptions to daily life. Businesses and homes near the shoreline are especially vulnerable. Additionally, the elevated sea levels could exacerbate beach erosion, impacting the local environment and tourism. Authorities are urging residents to remain vigilant and take necessary precautions to minimize risks.
