跟进：橙县大潮明起三天达峰值，Newport Beach 最高潮位或达8.5英尺，三处免费沙袋点持续开放
美国国家气象局对加利福尼亚州橙县与圣迭戈县沿海发布的洪水警告持续生效，King Tides 大潮将于明天（10月26日）起三天达到峰值：Newport Beach 市的修正预报显示，最高潮位周一上午或达8.3英尺、周二或达8.5英尺、周三约8.4英尺，且近期实际海水位比天文潮预报高出18至22英寸，低洼滨水社区的淹水风险高于预报数值。
Newport Beach 市已于10月19日宣布本地紧急状态并启用市应急行动中心，统筹防洪准备。市政府在三处地点向居民免费提供沙袋：592 Superior Ave.、1600 W. Balboa Blvd.，以及 Balboa 码头旁的 East Ocean Front 停车场。市议会同时批准了西 Newport 海滩补沙工程，将约10万立方码的沙从 Santa Ana 河口运往第36街至第62街之间受侵蚀的海滩，构筑防护沙堤；抽水泵与潮闸也已部署到易淹区域。
国家气象局警告，此次大潮可能给低洼沿海社区带来「显著的沿海洪水」。风险最高的区域包括 Balboa 半岛、Newport 港内的岛屿社区以及其他滨水低地。本月9日，热带风暴外围影响下海水曾漫过 Balboa 半岛街道，车辆在齐轮深的水中行驶，该市当时即关闭全部海滩并宣布紧急状态；本轮大潮是10月至新年之间一系列异常高潮位事件的第一轮，厄尔尼诺条件可能在未来数月继续推高海水位。沿海居民今明两天应提前固定户外物品、移走停在低洼处的车辆，并留意市政府与气象局的最新通告。
Follow-Up: King Tides Peak Over the Next Three Days in Orange County, With Newport Beach Tides Forecast Up to 8.5 Feet and Three Free Sandbag Sites Open
A National Weather Service coastal flood warning remains in effect for the Orange County and San Diego County coasts in California, and King Tides will peak over the three days beginning tomorrow, October 26. The City of Newport Beach's adjusted forecasts put the highest tides at about 8.3 feet Monday morning, 8.5 feet Tuesday and 8.4 feet Wednesday, and recent ocean water levels have been running 18 to 22 inches higher than astronomical predictions, raising the flood risk for low-lying waterfront neighborhoods above the forecast values.
Newport Beach declared a local emergency on October 19 and activated its Emergency Operations Center to coordinate preparations. Free sandbags are available to residents at three locations: 592 Superior Ave., 1600 W. Balboa Blvd., and the East Ocean Front Parking Lot near the Balboa Pier. The City Council has also approved the West Newport Beach Sand Replenishment Project, moving roughly 100,000 cubic yards of sand from the mouth of the Santa Ana River to eroded beaches between 36th and 62nd streets to rebuild protective berms; pumps and tide valves have been positioned in flood-prone areas.
The Weather Service warns the tides could bring "significant coastal flooding" to low-lying communities. The areas at highest risk include the Balboa Peninsula, the islands inside Newport Harbor and other waterfront lowlands. On October 9, ocean water swept across Balboa Peninsula streets, with vehicles driving through water halfway up their wheels, and the city closed all beaches and declared an emergency; this round of King Tides is the first in a series of unusually high tide events expected through October, November, December and into the new year, and El Niño conditions may keep water levels elevated in the months ahead. Coastal residents should secure outdoor items, move vehicles out of low-lying spots today and tomorrow, and follow city and Weather Service updates.
