Sneaker Wave Risk Tuesday

🌊 MODERATE SNEAKER WAVE RISK: A Moderate Risk of sneaker waves is in effect this Tuesday (1/20) for the Del Norte, Humboldt, and Mendocino coasts. Don't be fooled by an ocean that looks calm. Sneaker waves can surge hundreds of feet up the beach without warning—often after 30 minutes of much smaller waves. These waves are powerful enough to pull you into the frigid, high surf. 🛑 Stay off rock jetties and logs near the water. 🛑 Keep a safe distance from the surf zone. 🛑 NEVER turn your back on the ocean!
