Californians are being advised to brace for waves reaching up to 30 feet, multiple rounds of rain and strong winds this week. 

The National Weather Service has issued warnings of dangerous high surf and life-threatening currents beginning tonight in the San Francisco Bay Area. 

Forecasters expect water-related dangers to become deadly on Thursday, with breaking waves as high as 30 feet possible on northwest and west-facing beaches in the Area. Officials are asking beachgoers to stay out of the water, be mindful of the giant waves, especially on west-facing beaches, and stay away from rocks and jetties.
