The National Weather Service issued high surf advisories Thursday morning for Northern California, with 20-to-30-foot waves expected through Sunday.

LOS ANGELES — Northern California is bracing for another day of deadly waves topping 40 feet Tuesday as officials in Santa Cruz search for survivors and assess the damage from a partial collapse of the city’s landmark pier.

Persistent high surf and flooding threats along California's coast have residents on high alert a day after a major storm was blamed for one man's death and the partial collapse of a pier.

One man died and three people were thrown into the ocean after California's coast faced powerful waves and flooding Tuesday. This followed a major storm that caused widespread damage and left several people missing.
