旧金山湾区将迎危险大浪：碎浪25至35英尺、组浪最高50英尺
美国国家气象局旧金山湾区办公室 11 月 12 日发布高浪预警（High Surf Warning）：11 月 13 日（周五）下午 6 时至 11 月 15 日（周日）凌晨 4 时，旧金山湾区与 Monterey 湾的太平洋沿岸将出现 25 至 35 英尺的危险大碎浪，部分有利浪点的组浪可达 40 至 50 英尺。
预警覆盖北湾海岸（包括 Point Reyes National Seashore）、旧金山半岛海岸、Monterey 湾北部，以及旧金山市海岸、Monterey 湾南部与 Big Sur 海岸。
预警生效前，这一带先处于海滩危害声明之下，持续至周五下午：疯狗浪与强离岸流风险上升，碎浪 15 至 20 英尺。气象局同时发布海岸洪水提示：周五高潮时段，旧金山沿岸低洼地可能出现高出地面最高 1.5 英尺的淹水；旧金山验潮站周五中午 12 时 49 分的高潮预计达 7.3 英尺、比正常高 1.5 英尺，其中包括最高 1.8 英尺的风暴增水。周五午夜至周六下午 6 时，大浪将冲上沙滩、越过海堤，淹及邻近的低洼基础设施。
气象局表示，这样的碎浪能压倒游泳者，把人从沙滩、防波堤和礁石上卷入海中，造成严重身体伤害并显著增加溺水风险，海浪还可能毫无预警地横扫海岸线。涨潮还会造成低洼基础设施淹水、个别道路封闭与海岸侵蚀。气象局要求所有人远离水面，不要登上防波堤、码头与礁石，永远不要背对大海；驾车出行不要绕过路障，也不要驶入深度不明的积水。（来源：美国国家气象局）

Dangerously Large Surf to Hit San Francisco Bay Area Coast: Breaking Waves 25 to 35 Feet, Sets up to 50 Feet
The National Weather Service's San Francisco Bay Area office issued a High Surf Warning on November 12: from 6 p.m. Friday, November 13, to 4 a.m. Sunday, November 15, dangerously large breaking waves of 25 to 35 feet are expected along the Pacific coast of the San Francisco Bay Area and Monterey Bay, with occasional sets of 40 to 50 feet at favored breakpoints.
The warning covers the Coastal North Bay including Point Reyes National Seashore, the San Francisco Peninsula Coast and Northern Monterey Bay, as well as the San Francisco coast and the Southern Monterey Bay and Big Sur Coast.
Ahead of the warning, a Beach Hazards Statement remains in effect through Friday afternoon, with an increased risk of sneaker waves and strong rip currents and breaking waves of 15 to 20 feet. Coastal Flood Advisories are also in effect: up to 1.5 feet of inundation above ground level is possible in low-lying areas near shorelines and tidal waterways around high tide on Friday; at the San Francisco tide gauge, the high tide at 12:49 p.m. Friday is expected to reach 7.3 feet MLLW, 1.5 feet above normal, including up to 1.8 feet of surge. From midnight Friday night to 6 p.m. Saturday, large breaking waves will run up beaches and crash over seawalls, inundating adjacent low-lying infrastructure.
The Weather Service says the dangerously large breaking waves can overpower swimmers, pulling people into the sea from beaches, jetties and rocks, resulting in significant physical injury and increasing the risk of drowning, and that waves can sweep across the shoreline without warning. High tides will also bring flooding of low-lying infrastructure, isolated road closures and coastal erosion. Everyone should remain out of the water and stay off jetties, piers and rocks, and never turn their back on the ocean; drivers should not go around barricades or through water of unknown depth.
