High surf warning downgraded to high surf advisory

The National Weather Service downgraded a high surf warning for the central and northern California coastline to a high surf advisory Saturday afternoon.   

Wave heights -- which had reached 26 to 30 feet on Friday -- are expected to diminish to 16 to 20 feet on west-facing beaches, forecasters said.   

A high swell from the west-northwest will create hazardous beach conditions through 10 p.m., the weather service said in an advisory.
