* WHAT...For the High Surf Advisory, large breaking waves up to 22 to 25 feet. For the Beach Hazards Statement, increased threat of sneaker waves expected before the arrival of this very large swell. * WHERE...Mendocino Coast County. * WHEN...For the High Surf Advisory, from 6 PM this evening to 4 PM PST Thursday. For the Beach Hazards Statement, from 9 AM PST this morning through this afternoon. . * IMPACTS...Dangerous surf conditions and localized beach erosion. Beachcombing is highly discouraged! Large, unexpected waves can sweep across the beach without warning, sweeping people into the sea from rocks, jetties, and beaches. These sneaker waves can also move large objects such as logs, crushing anyone caught underneath.

Large breaking waves along the coast will lead to increased wave run-up on beaches with waves topping and washing over large rocks and jetties. These large waves can be erratic and unpredictable. Use extra caution near the surf zone as these large waves will be capable of sweeping people into the frigid and turbulent ocean water. Mariners traversing the bar are urged to exercise extreme caution or stay in port until the threat subsides. Please contact the U.S. Coast Guard for information regarding harbor and bar closures. Don't be fooled by an ocean that looks calm. There can be 30 minutes of small waves before a sneaker wave strikes. Avoid rocks and jetties. Avoid steep beaches. Stay much farther back from the water and never turn your back on the ocean.
