加州海岸遭十年来最大巨浪：Mavericks组浪达50至60英尺，圣克鲁斯县约270户收到疏散警告
美国国家气象局表示，11月14日（周六），十多年来最大的巨浪冲击加利福尼亚州海岸，从俄勒冈州界到洛杉矶县多处海滩与码头关闭，Half Moon Bay 外海的 Mavericks 浪点出现50至60英尺的组浪，圣克鲁斯县约270户低洼地区居民收到疏散警告。
气象局旧金山湾区办公室此前发布的高浪预警在周六得到验证：沿岸多数地段碎浪25至35英尺，Point Reyes 外海浮标周六上午测得有效波高31.2英尺，为该浮标近三十年记录中第二高，仅次于2015年12月厄尔尼诺冬季。气象局说，这样的海浪能把人从海滩、防波堤与礁石上卷入海中，溺水风险极高。
旧金山以南的 Pacifica 受冲击明显，海浪反复越过海堤涌入内陆数百英尺，1号公路部分路段积水近一英尺深，居民用沙袋保护住宅。圣克鲁斯县警长办公室与 Capitola 警方对 Capitola Village、Rio Del Mar 的 Las Olas 与 Beach Drive 一带、Platform Beach、Potbelly Beach 与 New Brighton State Beach 等低洼地带发出疏散警告，提醒居民考虑提前撤离；截至周六中午，该县尚未发布强制疏散令。圣克鲁斯市自周五晚起关闭全部市属海滩与圣克鲁斯码头，工作人员在沿岸堆起沙墙与挡板。
南加州方面，洛杉矶县海浪预计6至9英尺、增至8至12英尺，高浪提示持续至下周二下午，Manhattan Beach Pier 已因巨浪关闭，本站已有报道。气象局预计，下一轮大涌浪将于周日晚至周一抵达，危险海况下周还将持续。

Biggest Waves in a Decade Slam California Coast: Sets Reach 50 to 60 Feet at Mavericks, About 270 Santa Cruz County Homes Under Evacuation Warnings
The National Weather Service said the biggest waves in about a decade battered the California coast on Saturday, November 14, closing beaches and piers from the Oregon border to Los Angeles County, sending sets of 50 to 60 feet into the Mavericks break off Half Moon Bay, and prompting evacuation warnings for about 270 homes in Santa Cruz County.
The Bay Area office's High Surf Warning was borne out on Saturday: breaking waves of 25 to 35 feet hit much of the coast, and a buoy off Point Reyes measured a significant wave height of 31.2 feet on Saturday morning, the second highest in roughly three decades of records for that buoy, topped only during the December 2015 El Nino winter. The weather service said surf of this size can sweep people off beaches, jetties and rocks, and that the risk of drowning was very high.
In Pacifica, just south of San Francisco, waves repeatedly broke over the seawall and pushed water hundreds of feet inland; floodwater nearly a foot deep covered part of Highway 1, and residents filled sandbags to protect their homes. The Santa Cruz County Sheriff's Office and Capitola police issued evacuation warnings for low-lying areas including Capitola Village, the Las Olas and Beach Drive neighborhoods of Rio Del Mar, Platform Beach, Potbelly Beach and New Brighton State Beach, urging residents to consider leaving early; no evacuation orders had been issued as of midday Saturday. The City of Santa Cruz closed all city beaches and the Santa Cruz Wharf from Friday night, and crews built sand berms and barriers along the shore.
In Southern California, surf in Los Angeles County was forecast at 6 to 9 feet, building to 8 to 12 feet, with a high surf advisory in effect through Tuesday afternoon; the Manhattan Beach Pier has closed because of the large surf, as GSM has reported. Forecasters expected the next large swell to arrive late Sunday into Monday, with dangerous seas continuing into the coming week.
