Beach Hazards Statement

Moderate Sneaker Wave Threat

A Beach Hazards Statement has been issued for a moderate sneaker wave threat late Thursday through late Friday. Warm, mild conditions are expected as a long period NW swell fills into the waters. Large, unexpected waves can sweep across the beach without warning, sweeping people into the sea from rocks, jetties, and beaches. 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, steep beaches, and never turn your back on the ocean.
