California Braces for Coastal Flooding Amid Elevated King Tides

Coastal areas across Southern California are on alert for potential flooding as “very high” king tides are forecast to hit the region. The National Weather Service (NWS) has issued a coastal flood advisory for Los Angeles, Ventura, Santa Barbara, and San Luis Obispo counties, effective from Sunday morning through Thursday afternoon.

During this period, high tides are expected to reach approximately eight feet each morning. Forecasters predict these tides will be 1.0 to 1.5 feet higher than astronomical projections. Similar conditions and advisories have also been issued for San Diego and Orange counties.

The NWS advises coastal residents to remain vigilant for rising water levels and to take necessary precautions to protect life and property. The high tides are anticipated to occur in the mornings, with levels potentially ranging from 1 to 1.7 feet above predicted astronomical tide levels.

This surge in tidal activity coincides with a forecast for a “wet Halloween weekend” across Southern California, according to the NWS. The weather service has indicated a high probability of measurable rainfall from Friday through the weekend, though specific timing and totals remain uncertain. Residents should anticipate that Halloween activities may be affected by rain.

Earlier this week, Newport Beach declared a local emergency in anticipation of the high king tides. Coastal water levels in Newport Beach were expected to crest at elevated heights between October 26 and 28. The tides were predicted to reach 6.5 feet on October 26, potentially peaking at 8.3 feet, with higher crests of 6.7 feet up to 8.5 feet expected on October 27. Elevated conditions were anticipated to continue on October 28. In response, Newport Beach has activated its emergency operations center to manage flood prevention and response efforts.
