A High Surf Warning has been issued along the coast from Sonoma County through Monterey County from 9 AM Sunday to 9 PM Monday. A High Surf Warning indicates that dangerous, life threatening waves will impact the shoreline. It is advised that people remain off of and away from the shoreline during this event. Very long period forerunner waves will arrive through the day Sunday and will bring a significantly increased risk of rip currents and sneaker waves to the coast. The largest waves are then forecast to arrive Sunday night through Monday morning, with peak swells of 17 to 21 ft at 19 to 21 seconds expected. Large breaking waves of 25 to 40 ft will be possible at west and northwest facing locations, with up to or exceeding 50 ft possible at favored break points along the coast. These large waves along the coast will lead to increased wave run-up on beaches with waves topping and washing over large rocks and jetties. Use extreme caution near the surf zone as these large waves will be capable of sweeping people into the frigid and turbulent ocean water.
