Big Swells to Pound Local Beaches

A large winter storm in the western Pacific Ocean could cause some dangerous condition along Southern California beaches this weekend. The swells were at 3-5 feet in height this morning, but should grow to 8 feet Sunday, the National Weather Service said in a statement.

Large swells with 24-second intervals should arrive today, the Weather Service said, while a slight Santa Ana condition will minimize chop in Santa Monica Bay.

That combination could mean large, but infrequent, breakers will suddenly appear and soak dry sand, the Weather Service said.

Beaches and jetties with western exposures are particularly at risk for a sudden run-up. That means strong "surging-type conditions" with six-foot waves are possible. "Breakers will inundate previously dry shores and overtop jetties without warning," the Weather Service said.
