High surf, possible flooding expected along Southern California coast

Forecasters are warning beachgoers to stay out of the ocean in anticipation of dangerous surf on Southern California beaches starting tonight.

A high surf advisory will be in effect from 8 tonight to 9 a.m. Friday as a large west swell combines with high tides over the next few days, the National Weather Service says.

Waves are expected to reach 8 to 12 feet on beaches in Los Angeles and Ventura counties, and as high as 17 feet on exposed, west-facing beaches. Dangerous rip currents are predicted on all beaches through Friday. At its peak, surf is expected to reach an average height of 15 to 20 feet along the Central Coast.

“Even the most experienced swimmers should stay out of the water during this event,” National Weather Service officials said in a statement.

Stuart Seto, a weather specialist with the agency, warned people to stay off coastal rocks and jetties.

“All of a sudden, a big wave comes that can wash you right out from the rocks or carry you out to the ocean,” he said.

The National Weather Service has issued a coastal flood watch for late tonight through Friday afternoon.

“Residents in low-lying beach areas susceptible to coastal flooding should act now to protect property,” agency officials said in a statement.

Forecasters say there could be 1/10 to 1/4 of an inch of rain starting tonight, but it is not expected to be enough to contribute to any flooding.
