加州橙县Newport Beach市大潮创有记录以来最高：10月27日高潮8.4英尺，市府提醒感恩节前后或再高6至12英寸
位于加州橙县的 Newport Beach 市本周经历了有记录以来最高的大潮。市经理 Seimone Jurjis 在市府10月30日发布的每周社区更新中说，10月27日星期二，该市录得高潮8.4英尺，为自1920年代有记录以来的最高值。多处低洼地区被淹，但市府称，由于居民认真对待预警、与市府团队一起放置了数千个沙袋并安装临时防洪挡板，实际影响没有可能出现的那么严重。
市府称，仅过去一周，市府团队就分发了5万多个沙袋，其中1.6万个由工作人员和志愿者手工灌装；团队还日夜加固防护沙堤、操作水泵并监测水位。
市府同时提醒，最高潮位可能还在后面。据美国国家海洋和大气管理局（NOAA）预计，感恩节前后、即11月23日至27日将再迎一轮国王潮，12月和1月还有更多；按目前海洋状况，水位可能比周二8.4英尺的纪录再高6至12英寸，有可能突破9英尺。市府解释，海水变暖膨胀、风向与海洋环流变化，加上月球与太阳引力造成的特大潮汐（国王潮），多重因素叠加推高了沿岸水位。
市府请低洼与临水地区的居民保留沙袋和临时防洪挡板、不要拆除，继续检查海堤、加固薄弱部位。免费预灌沙袋可在以下两处领取，送完为止：市政场院（City Corporation Yard，592 Superior Ave）与 Marina Park（1600 W. Balboa Blvd）。本周末还预计有降雨，市府提醒市民不要踩踏海滩边的防护沙堤，以免削弱屏障；最新消息、沙袋领取点与防洪准备资源见市府的厄尔尼诺与防洪准备页面。

Newport Beach, Orange County Records Its Highest Tide Ever at 8.4 Feet: City Warns Thanksgiving King Tides Could Run 6 to 12 Inches Higher
The City of Newport Beach in Orange County, California, recorded a high tide of 8.4 feet on Tuesday, October 27, the highest in the city's recorded history, with records dating back to the 1920s, City Manager Seimone Jurjis said in the city's October 30 weekly update. Several low-lying areas flooded, but the city said impacts were less severe than they could have been because residents took warnings seriously, placed thousands of sandbags and installed temporary flood barriers alongside city teams.
Over the past week alone, city teams distributed more than 50,000 sandbags, 16,000 of them filled by hand by staff and volunteers, while crews reinforced protective sand berms, operated pumps and monitored water levels around the clock, according to the update.
The city warned that the highest tides may still be ahead. According to the National Oceanic and Atmospheric Administration (NOAA), another round of King Tides is expected around Thanksgiving, November 23 through 27, with additional King Tides in December and in January. Based on current ocean conditions, water levels could rise another 6 to 12 inches above Tuesday's 8.4-foot record, potentially pushing above 9 feet. The city said warmer ocean water, changes in winds and ocean circulation, and the gravitational pull of the moon and sun are combining to produce the exceptionally high tides.
Residents in low-lying and waterfront areas are asked to keep sandbags and temporary flood barriers in place, continue inspecting seawalls and reinforce vulnerable areas. Free prefilled sandbags are available, while supplies last, at the City Corporation Yard, 592 Superior Ave, and at Marina Park, 1600 W. Balboa Blvd. With rain also expected this weekend, the city reminded everyone to stay off the protective sand berms along the beaches, as walking or climbing on them can weaken the barriers. Updates, sandbag locations and flood preparation resources are posted on the city's El Niño and flood preparation page.
