跟进：圣迭戈县与橙县海岸洪水警告持续至周四下午1点：大潮实测高出预报逾1.4英尺
美国国家气象局圣迭戈办公室发布的海岸洪水警告仍在生效：加利福尼亚州圣迭戈县与橙县沿海地区在周四（10月29日）上午晚些时候的大潮时段可能出现严重海岸洪水，警告持续至周四下午1点。圣迭戈县政府提醒沿海居民留意道路封闭与低洼地带进水，并公布了县内沙袋领取点信息。
气象局10月27日晚9点34分发布这则警告时指出，实测潮位已比预报高出约1.4至1.6英尺。警告称，大潮叠加高出预报的潮位，可能淹没低洼的住宅、商铺与基础设施，部分沿海道路可能关闭，海岸线侵蚀也会加剧。
本轮大潮（king tides）自本周初起影响南加州海岸：橙县纽波特滩（Newport Beach）一带此前已出现海水倒灌与太平洋海岸公路（PCH）部分路段封闭，洛杉矶县与圣迭戈县多处海滩也报告了潮水漫堤。
圣迭戈县应急部门建议沿海居民把车辆移离低洼地带，不要驾车穿越被淹道路，并通过县府Alert San Diego系统登记接收警报。县府在官网列出了各城市沙袋领取点的地址与开放时间。
气象局表示，周四下午之后潮位将逐步回落，但本周末仍有较高潮位，沿海居民应继续留意后续通告。
Follow-Up: Coastal Flood Warning for San Diego and Orange County Coasts Runs Through Thursday 1 p.m. as King Tides Run Above Predictions
A Coastal Flood Warning from the National Weather Service office in San Diego remains in effect for the coasts of San Diego County and Orange County, California, through 1 p.m. on Thursday, October 29, with significant coastal flooding possible around the late-morning high tide. San Diego County officials urged coastal residents to watch for road closures and low-lying flooding and published the county's sandbag distribution locations.
When the Weather Service issued the warning at 9:34 p.m. on October 27, observed tides were already running about 1.4 to 1.6 feet above predictions. The warning says the combination could inundate low-lying homes, businesses and infrastructure, close some coastal roads and worsen shoreline erosion.
This week's king tides have been affecting the Southern California coast since early in the week: seawater flooding and partial closures of Pacific Coast Highway were reported around Newport Beach in Orange County, and tides overtopped seawalls at beaches in Los Angeles and San Diego counties.
San Diego County emergency officials advised coastal residents to move vehicles out of low-lying areas, never drive through flooded roads, and sign up for alerts through Alert San Diego. The county lists sandbag pickup sites and hours on its website.
The Weather Service said tides will gradually ease after Thursday afternoon, though elevated tides continue into the weekend and residents should keep checking for updated advisories.
