The elevated tides have already caused flooding in streets, homes, and businesses in low-lying areas like Newport Beach, Huntington Beach, and Balboa Island. The upcoming king tides during Thanksgiving and Christmas weeks pose a significant risk to coastal neighborhoods, with potential for further flooding and property damage. Residents are advised to prepare for water levels exceeding predictions, especially in areas prone to tidal flooding. The strong El Niño also raises the likelihood of stormier conditions, which could compound the risks.
