Forecasters warn of risk of sneaker waves along Bay Area coast

Weather forecasters are warning of an increased risk of sneaker waves and rip currents along Bay Area coastlines through early Tuesday.

A beach hazards statement was issued Monday by the National Weather Service for shorelines from the North Bay to Big Sur, with northwest-facing beaches most at risk.

"Sneaker waves can sweep people and pets into the sea from rocks, jetties, and beaches as well as move large objects such as logs, crushing anyone caught underneath," according to the weather service.

Beachgoers are advised to avoid swimming and never turn their backs on the ocean.

"Don't be fooled by an ocean that looks calm. There can be 30 minutes of small waves before a sneaker wave strikes," the weather service advised.

In late November, a 5-year-old Merced girl died after being swept out to sea by a wave at Martins Beach in Half Moon Bay. Her 54-year-old grandfather went missing in the ocean after trying to rescue her, and searchers were unable to find him.
