飓风伊梅尔达和亨伯托对美国东海岸及百慕大构成双重威胁

摘要

热带风暴伊梅尔达预计将加强为飓风,给美国东海岸带来危险天气,而飓风亨伯托作为四级风暴正逼近百慕大。

热带风暴伊梅尔达预计将在本周沿佛罗里达东海岸平行移动时增强为飓风,带来大雨、强风和从佛罗里达到卡罗莱纳州的海平面升高。

截至2025年9月29日星期一,伊梅尔达位于佛罗里达卡纳维拉尔角东南约320英里处,向北移动,时速9英里,持续风速为50英里每小时。预计该风暴将在周二达到飓风强度,然后转向东进入大西洋。

与此同时,飓风亨伯托已增强为强大的四级风暴,持续风速达145英里每小时。该飓风正向东北方向逼近百慕大,预计将从岛屿西侧经过,可能给该地区带来恶劣天气。

伊梅尔达和亨伯托之间的相互作用可能会影响它们各自的路径,这种现象称为藤原效应,即两个相近的气旋相互绕转。预计这种相互作用将把伊梅尔达拉离美国海岸线,减少其直接登陆的威胁。

尽管登陆风险降低,美国东海岸仍预计将经历危险天气。预报显示,南卡罗来纳州沿海和北卡罗来纳州东南部可能降雨2至4英寸,局部地区降雨量可达6英寸,可能引发洪水。

针对即将来临的风暴,东南部官员已启动预防措施。南卡罗来纳州州长亨利·麦克马斯特宣布进入紧急状态,启动全州响应计划,查尔斯顿市也宣布地方紧急状态,开始分发沙袋并清理排水系统。

百慕大正为飓风亨伯托的影响做准备,已发布警告,敦促居民采取必要防范措施。该岛面临罕见的双重打击可能,伊梅尔达可能更接近百慕大,预计本周晚些时候可能直接登陆。

巴哈马群岛在周末经历了伊梅尔达带来的风雨洗礼,目前部分岛屿仍处于热带风暴警告中,预计降雨4至8英寸,可能引发山洪暴发。

截至目前,今年美国尚未遭遇飓风直接登陆。今年7月,热带风暴尚塔尔登陆南卡罗来纳州,但2025年尚无风暴以飓风强度抵达海岸。如果这一趋势持续,将是十年来首次无飓风登陆的季节。
