跟进：Newport Beach 提醒备战下一轮国王潮：11月23日至27日潮位或比10月纪录再高12英寸

位于加州橙县的 Newport Beach 市政府11月4日发布提醒，请居民与业主立即为下一轮异常高潮做好防备：国王潮预计在11月23日至27日、12月22日至26日接连到来，并延续到新年，届时海水水位可能比10月创纪录的8.4英尺高潮再高12英寸或更多。

市府表示，这样的水位会显著增加低洼社区、滨水地带等易涝区域的海岸洪水风险，包括10月没有进水的房产也可能受淹。海水只要越过或穿透一段低矮、破损或老化的海堤，就可能淹及住宅、车辆、邻近房产与街道。业主受促尽快检查自家海堤并在下一轮高潮到来前采取防护措施。

市府工作队正在持续加固防护沙堤、检查雨水基础设施、维护潮阀与抽水系统，并在易涝地区预置沙袋、设备与人员，工作人员将监测海岸状况并按需响应。市府同时说明，这些措施无法消除全部影响，滨水业主与易涝区居民仍须自行做好防护。

在具体防护上，市府建议在低矮海堤、车库、门口等可能进水处放置沙袋或临时挡水设施，检查私人排水口与潮阀是否会倒灌；检查海堤与驳岸有无低段、裂缝、孔洞或老化并及时修补。加州海岸委员会已授权市府为海堤维修与加高签发紧急许可，简化图纸与加快审批均可办理，详情可向市社区发展部咨询（电话 949-644-3200）。市府还建议考虑购置或租用临时水泵处理轻微渗漏，但提醒水泵无法应对海堤漫顶或大规模洪水。

出行与用电安全方面，市府提醒切勿驾车穿过被淹街道，车辆尾流会把水推向附近房产、加重水淹；船主在异常高潮期间应减少在 Newport Harbor 的活动，船行波浪同样可能让海水漫过海堤。电动车、高尔夫球车与电动自行车应移往高处，洪水尤其是海水会损坏锂离子电池、在水退后仍有起火风险；被洪水泡过的电池不要使用或充电，应先由专业人员检查，如出现变色、鼓包或冒烟应立即远离并拨打911。

免费预装沙袋可在市府 Corporation Yard（592 Superior Ave）领取，空沙袋可在各消防站与救生总部（70 Newport Pier）领取，均为领完为止。业主对自有房产的维护与防护措施负责，市府无法保证房产不进水。

Newport Beach 市议会将于11月10日（周二）下午4时举行专题学习会，讨论下一轮国王潮的防洪、公共安全与应急响应计划，以及居民可采取的防护步骤。市府建议居民通过其官网的防洪与厄尔尼诺信息页查看后续国王潮日期、预计水位与沙袋信息，注册 Newport Notified 紧急警报，并关注市府官方社交账号获取更新；遇危及生命安全的紧急情况拨打911。

Follow-Up: Newport Beach Urges Preparation for Next King Tides, Nov. 23-27 Levels Could Top October Record by 12 Inches

The City of Newport Beach, in Orange County, California, on November 4 asked residents and property owners to take immediate precautions ahead of exceptionally high king tides expected Nov. 23-27 and Dec. 22-26 and into the new year, as ocean water levels could rise 12 inches or more above October's record-breaking high tide of 8.4 feet.

The city said the conditions could significantly increase the risk of coastal flooding in low-lying neighborhoods, waterfront areas and other flood-prone areas, including properties that did not experience flooding in October. Water overtopping or passing through even one low, damaged or deteriorating seawall could flood homes, vehicles, neighboring properties and streets, and property owners were asked to inspect their seawalls and take protective measures before the next high tide event.

City crews continue reinforcing protective sand berms, inspecting stormwater infrastructure, maintaining tide valves and pumping systems, and positioning sandbags, equipment and personnel in flood-prone areas, and staff will monitor coastal conditions and respond as needed. The city noted that these efforts cannot eliminate all potential impacts.

Residents were advised to place sandbags or temporary flood barriers along low seawalls, garages, doorways and other openings, and to check private drains and tide valves for potential backflow. Seawalls and bulkheads should be inspected for low sections, cracks, openings or deterioration and repaired as needed. The city has received authorization from the California Coastal Commission to issue emergency permits for seawall repairs and extensions, with streamlined plans and expedited permitting available through the Community Development Department at 949-644-3200. Temporary pumps can help manage minor leaks, the city said, but cannot manage seawall overtopping or major flooding.

On roads and waterways, the city warned residents never to drive through flooded streets, since vehicle wakes can push water onto nearby properties, and asked boaters to limit activity in Newport Harbor during exceptionally high tides because boat wakes can overtop seawalls. Vehicles, including electric vehicles, golf carts and e-bikes, should be moved to higher ground, because floodwater, especially saltwater, can damage lithium-ion batteries and create a fire risk even after the water recedes. A battery exposed to floodwater should not be operated or charged until inspected by a qualified professional, and anyone who sees discoloration, swelling or smoke should stay away and call 911.

Free, prefilled sandbags are available at the city's Corporation Yard, 592 Superior Ave, and empty sandbags are available at Newport Beach fire stations and Lifeguard Headquarters, 70 Newport Pier, while supplies last. Property owners are responsible for maintaining their private property, and the city cannot guarantee protection from flooding.

The Newport Beach City Council will hold a study session on Tuesday, Nov. 10, at 4 p.m. to discuss flood protection, public safety and emergency response plans for the upcoming king tide events. The city pointed residents to its flood preparedness and El Niño resources for upcoming king tide dates, anticipated water levels and sandbag information, encouraged sign-ups for Newport Notified emergency alerts, and said anyone facing an immediate threat to life or safety should call 911.
