SAN FRANCISCO (AP) - U.S. Coast Guard officials are warning the public to stay away from the water's edge Friday because of high waves.
The San Francisco Chronicle reports that the combination of high winds and high surf is dangerous for beachgoers, boaters and surfers.
Forecasters say a storm to the northwest Wednesday night generated the strong crests. Additionally, cool air that trailed it was responsible for the brisk winds, which reached about 35 mph in the area of San Francisco International Airport on Thursday afternoon, the newspaper reported.
The weather service is also warning of large shore breaks. These occur when a massive wave breaks in shallow water, frequently resulting in back or neck injuries.
Forecasters say that by Saturday, wave heights will fall to between six and nine feet.
