SUNSET BEACH, Calif. (KTLA) — Some coastal communities are again bracing for the threat of “king tides” and potential flooding.
The super swells strike the coast between two and four times a year when the gravitational forces of the sun, Earth and moon are all in alignment.
Thursday and Friday the perfect combination is expected again.
Coastal areas along Pacific Coast Highway near Seal Beach and Sunset Beach are particularly vulnerable.
Back in December, there was significant flooding from king tides in both Sunset Beach and Newport Beach.
The high tide in Huntington Harbor in Sunset Beach was 6.8 feet at 7:22 a.m. Thursday, but things stayed mostly dry.
A high tide of 6.9 feet is due at 8:09 a.m. Friday. Huntington Beach Public Works crews are on alert with pumps ready in case there is flooding.
The National Weather Service has issued a coastal flood advisory through Saturday for the Orange County coastal areas.
Rain and heavy surf are both in the forecast, which could make flooding from the king tides even worse.
A high surf advisory has been issued through Saturday for west-facing beaches in Ventura, Los Angeles and Orange counties.
Occasional sets of 6 to 8 feet are possible on Thursday for west-facing shores, forecasters said.
