Sneaker wave danger at Bay Area beaches: 'Never turn your back to the ocean'
A northwesterly swell will continue to send dangerous waves to San Francisco Bay Area beaches Tuesday, leading the National Weather Service to issue a warning to "never turn your back to the ocean."
A beach hazards statement alerting the public of an increased risk of sneaker waves and rip currents is in effect from Sonoma County to Monterey County through 3 p.m. Tuesday afternoon.
The ocean may appear calm before a larger so-called sneaker wave runs farther up the beach. "These waves sneak up on people when they're not anticipating it," said Roger Gass, a meteorologist with the NWS's Monterey office.
The sneaker waves will be of particular concern on steep-sloping beaches. "Rock jetties can be deadly in such conditions, stay off the rocks," warns the NWS.
Rip currents can pull swimmers and surfers out to sea.
