The National Weather Service has issued a high surf advisory in affect for the central coast with large waves and hazardous surf conditions until 7pm this evening. Destructive waves may wash over beaches, jetties, and other structures unexpectedly. People can be swept off rocks and jetties and drown while observing high surf. Minor beach erosion may damage coastal properties and buildings. Higher than normal water run-up is expected on beaches and low-lying shoreline. There is an enhanced threat of sneaker waves today. Some waves may run up the beach much farther than the average breaking waves. A High Surf Advisory means that high surf will affect beaches resulting in rip currents, sneaker waves, and beach erosion. Stay well back from the water`s edge and be alert for exceptionally high waves. Keep away from large logs on the beach. Water running up on the beach can easily lift or roll logs which can injure or kill someone caught in their path.
