A strong storm system over the central Pacific will send a swell that is expected to produce waves of 10 to 19 feet along the California coastline, forecasters warned.
Breakers of 7 to possibly 12 feet are expected to start hitting the shores along Los Angeles and Ventura counties Thursday night, with peak sets coming on Friday, according to the National Weather Service.
Along the Central Coast, breakers could hit 19 feet.
A high surf advisory issued by the weather service will be in effect from 6 p.m. Thursday to 3 a.m. Sunday, with forecasters warning of strong rip currents and possible beach erosion.
The swells are being generated by a huge storm surge that already has produced some of the largest waves to have hit Hawaii in decades.
