俄勒冈海岸周末大浪警报：碎波可达28英尺，海滩危险声明持续至周六深夜
美国国家气象局（NWS）Portland 办公室11月6日下午12时57分更新警报：俄勒冈州北部与中部海岸以及华盛顿州南部海岸的海滩危险声明持续生效至周六深夜，海滩上可能出现突袭浪（sneaker waves）；紧接着的大浪警报将于周日上午4时生效、持续至当晚10时，大浪与危险的冲浪条件并存，碎波最高可达28英尺。
气象局表示，破坏性海浪可能出其不意地冲过海滩、防波堤和其他建筑物；人们可能被冲下岩石和防波堤而溺亡，海滩还可能出现轻微侵蚀、损坏沿海房产与建筑。突袭浪会让海水冲上比平常高得多的位置，能突然把人掀翻在地、迅速拖入冰冷的海水，可能造成重伤或溺水。
气象局提醒，在水中或水边活动要格外小心，尤其是采挖蛏子的人；让儿童和宠物远离冲浪区，不要登上防波堤、岩石和水线附近的木头；如果看到有人被卷入海中，不要下水施救，应拨打911并持续注视落水者直至救援人员抵达。气象局同时表示，大浪警报意味着大浪将影响海滩、产生离岸流、突袭浪和海滩侵蚀，人们应远离水线、警惕异常高的大浪；海滩上的大木头也要远离，冲上岸的海水很容易掀动或滚动木头，压伤甚至压死躲闪不及的人。
气象局 Medford 办公室同日也对俄勒冈州中南部海岸与 Curry 县海岸发布了海滩危险声明（生效至周五晚10时）与周日的大浪警报，当地碎波预计达22至27英尺，突袭浪风险同样升高。（来源：美国国家气象局）
High Surf Advisory for Oregon Coast This Weekend: Breakers Up to 28 Feet, Beach Hazards Statement Through Late Saturday Night
The National Weather Service (NWS) office in Portland updated its coastal alerts at 12:57 p.m. PST on November 6: a Beach Hazards Statement remains in effect through late Saturday night for the North and Central Coast of Oregon and the South Washington Coast, with sneaker waves possible on the beaches. A High Surf Advisory follows from 4 a.m. to 10 p.m. PST on Sunday, bringing large waves, hazardous surf conditions and sneaker waves, with breakers up to 28 feet.
The Weather Service said destructive waves may wash over beaches, jetties and other structures unexpectedly, and people can be swept off rocks and jetties and drown while observing high surf. Minor beach erosion may damage coastal properties and buildings. Because of sneaker waves, higher than normal water run-up is expected on beaches and low-lying shoreline; sneaker waves can suddenly knock people off their feet and quickly pull them into the frigid ocean, which may lead to serious injury or drowning.
The Weather Service urged caution in or near the water, especially for people razor clamming. Children and pets should be kept away from the surf zone, and people should keep off jetties, rocks and logs near the surf zone. Anyone who sees a person swept into the sea should not swim in after them, but call 911 and keep an eye on them until help arrives. A High Surf Advisory means high surf will affect beaches, producing rip currents, sneaker waves and beach erosion; people should stay well back from the water's edge and be alert for exceptionally high waves, and keep away from large logs on the beach, which water running up the beach can easily lift or roll, injuring or killing anyone caught in their path.
The NWS office in Medford issued a similar Beach Hazards Statement for the South Central Oregon Coast and Curry County Coast, in effect until 10 p.m. Friday, along with a High Surf Advisory for Sunday, with large breaking waves of 22 to 27 feet and an elevated risk of sneaker waves.
