热带低压九号预计加强为飓风伊梅尔达,可能影响美国东海岸

摘要

热带低压九号预计将加强为飓风伊梅尔达,可能在下周初对美国东海岸产生影响。

热带低压九号预计将在今天晚些时候加强为热带风暴伊梅尔达,并可能在下周初达到飓风级别,威胁美国东海岸。截至周日上午,该系统位于古巴西北偏北约285英里处,最大持续风速为35英里/小时,向北偏北方向以7英里/小时速度移动。

目前,巴哈马中部和西北部已发布热带风暴警告,预计将有大雨,降雨量在4至12英寸之间。这一降雨量可能导致受影响地区发生山洪暴发。

伊梅尔达的预测路径在过去24至36小时内有所调整,现在显示其直接登陆美国东南海岸的可能性降低。预计该风暴将向北移动,沿佛罗里达大西洋海岸平行经过至周一,然后转向东离开海岸,并在周二或周三加强为飓风。

尽管路径有所变化,东南海岸居民仍被建议保持警惕,因为风暴路径仍可能改变。国家飓风中心周日早些时候表示:“虽然现在还不能非常确定,但几乎所有可靠的(预测模型)集合现在都显示该系统将保持在美国东南部海岸外,尽管仍预期会有一些影响。”

潜在影响包括降雨引发的洪水,特别是在沿海卡罗莱纳州,以及可能导致巨浪、沿海洪水和海滩侵蚀的陆风。预计沿海卡罗莱纳州至周三上午的降雨量为1至5英寸。

为应对即将来临的风暴,南卡罗来纳州州长亨利·麦克马斯特于周五宣布进入紧急状态,启动全州响应计划并动员各机构准备应对全州范围内的强风、洪水和风暴潮。查尔斯顿市于周六宣布地方紧急状态,采取措施如分发沙袋和清理排水沟。

与此同时,在大西洋公海,飓风亨伯托迅速增强为五级飓风,持续风速达160英里/小时。虽然它对美国没有直接威胁,但预计亨伯托将影响伊梅尔达的轨迹。两系统之间的相互作用,被称为富士华拉效应,可能导致亨伯托将伊梅尔达拉向东部,从而可能使美国海岸免受重大损害。

从巴哈马到美国东南海岸及百慕大地区的居民被建议密切关注预测,随着情况发展,降雨、风力和沿海洪水的可能性将在未来几天变得更加明确。
