SAN DIEGO — Winter charged on day one Saturday, as a dangerous northwest swell raced across the Pacific and triggered high surf alerts from Hawaii to California. The most urgent big-wave alert, a high surf warning, is in effect for parts of Hawaii, including surfing's mecca, the North Shore, where waves of 50 feet are possible Sunday, according to the National Weather Service. The warnings are issued when waves pose a threat to life and property, the weather service says. The biggest waves in Southern California could reach 13 feet and will likely be found in San Diego County, it said. Big waves were also forecast for the West Coast up to the U.S.-Canada border, with the weather service in Seattle calling for waves as high as 30 feet and the office that covers Portland, Oregon, predicting waves as high as 33 feet.
