橙县海岸海滩危险声明持续至今晚11时：危险离岸流、大浪3至5英尺 南向海滩或有海水漫滩侵蚀
美国国家气象局圣迭戈办公室（NWS San Diego）10月20日下午1时29分更新海滩危险声明（Beach Hazards Statement），覆盖位于加州橙县的沿海地带与圣迭戈县沿海地区，声明有效至今晚（10月20日）11时。橙县沿线海滩包括 Seal Beach、Huntington Beach、Newport Beach、Laguna Beach、Dana Point 与 San Clemente 等地。
声明指出，上述海域将出现危险的离岸流与碎浪，浪高3至5英尺，局部阵浪可达6英尺，朝南与西南向的海滩浪势最高。
气象局表示，危险的游泳条件已经形成：离岸流可将游泳者与冲浪者卷向外海，大浪可将人冲离海滩与礁石，也可掀翻近岸小船；朝南的海滩还可能出现轻微的海滩侵蚀与海水漫滩。
气象局在声明中给出的指令是「留在水外」（Remain out of the water），以避开危险的游泳条件。据气象局记录，这份海滩危险声明自10月18日起连续滚动发布，本次为最新一次更新。
气象局同日还对加州其他地区发布了洪水监视（Flood Watch），范围包括洛杉矶县、Ventura 县与 Santa Barbara 县沿海及中央谷地部分地区，有效至10月21日上午；橙县沿海不在洪水监视范围内，橙县现行生效的是上述海滩危险声明。
Beach Hazards Statement in Effect for Orange County Coast Until 11 PM: Dangerous Rip Currents, Surf of 3 to 5 Feet
The National Weather Service office in San Diego (NWS San Diego) updated a Beach Hazards Statement at 1:29 p.m. on October 20 covering the coastal areas of Orange County and San Diego County, California, in effect through 11 p.m. tonight (October 20). Orange County shoreline covered by the statement includes Seal Beach, Huntington Beach, Newport Beach, Laguna Beach, Dana Point and San Clemente.
The statement warns of dangerous rip currents and breaking waves, with surf of 3 to 5 feet and local sets to 6 feet, highest on south and southwest facing beaches.
The Weather Service said hazardous swimming conditions are in place: rip currents can pull swimmers and surfers out to sea, waves can wash people off beaches and rocks and can capsize small boats near shore, and minor beach erosion may occur across south-facing beaches.
The agency's instruction in the statement is to remain out of the water to avoid hazardous swimming conditions. NWS records show the Beach Hazards Statement has been issued in updated form since October 18, and this is the latest update.
The Weather Service also has Flood Watches in effect for other parts of California, including the Los Angeles, Ventura and Santa Barbara county coasts and parts of the Central Valley, through the morning of October 21. The Orange County coast is not under a Flood Watch; the Beach Hazards Statement is the alert in effect there.
