12-Foot Waves Expected at West-Facing Beaches This Weekend

A storm system has reached Southern California, bringing rain, heavy surf, and potential flooding to coastal areas.

The first phase of the weather event delivered scattered showers to Southern California on Thursday, while Northern California received the bulk of the initial rainfall. Forecasters indicate that the heaviest precipitation will arrive Friday afternoon and continue through Saturday morning.

Rainfall totals are expected to range from a quarter-inch to an inch by Saturday. Mike Wofford, a meteorologist with the National Weather Service Oxnard office, noted that while the rain is generally light, heavier bursts are possible. Wofford stated that minor flood advisories may be issued over the weekend. The National Weather Service warned of moderate coastal flooding impacts for Los Angeles County beaches, particularly on Saturday. These impacts may include beach erosion and shallow flooding of dry beaches and walkways.

Two large swells have triggered a high surf advisory that remains in effect through Tuesday. The first swell arrived Friday and is expected to persist into Saturday, while the second is scheduled for Monday. Bryan Lewis, also of the NWS Oxnard office, predicted surf heights of 8 to 12 feet at west-facing beaches, though some areas may see lower levels. Swimmers are advised to watch for rip currents, swim near lifeguards, and avoid rock jetties.

The eastern Sierra region, specifically from Mt. Whitney to Aspendell, may receive up to a foot of snow over the weekend. The weather service warned that travel could be difficult or impossible, with hazardous conditions affecting the Friday evening commute. Strong winds may damage trees and power lines, while roads, bridges, and overpasses are likely to become slick.

Temperatures will feel warm during the day but will drop by about 10 degrees in the evening. The region can expect mid to high 60s for the remainder of the week starting Friday. This cooling trend is attributed to an offshore pattern swinging onshore. Gusty winds from the southwest to northwest are expected Friday, with sustained speeds near 20 mph and gusts of 30 to 35 mph in the inland region of Los Angeles County.
