The elevated sea levels and high tides pose a risk of coastal flooding, beach erosion, and dangerous rip currents, particularly in Southern California's Orange and San Diego Counties. While the current 'coastally trapped wave' is not inherently destructive, its combination with high tides and storms could lead to significant damage. The risk is expected to increase during the winter months, especially if 'king tides' align with coastal storms. Communities along the California coast, including beach towns and areas near the Sierra Nevada mountains, are preparing for potential severe weather impacts. Surfers are currently enjoying the tall surf, but residents and visitors are advised to remain cautious.
