飓风伊萨亚斯于周三晚间从热带风暴增强，预计本周末在美国墨西哥湾沿岸登陆，威胁密西西比州、阿拉巴马州以及佛罗里达狭长地带西部部分区域。它是2026年大西洋飓风季的首个飓风。
佛罗里达州州长罗恩·德桑蒂斯为该州二十多个县宣布进入紧急状态，调动资源应对风暴可能带来的严重影响；阿拉巴马州州长凯·艾维也为该州40个县发布了类似的紧急状态令。
根据美国国家飓风中心的数据，伊萨亚斯的最大持续风速为每小时75英里，当时位于密西西比河河口西南约460英里处。
地图展示飓风路径
预报人员表示，读音为“ees-ah-EE-ahs”的飓风伊萨亚斯预计将于周四从墨西哥尤卡坦半岛北部经过，随后于周五向墨西哥湾沿岸移动。美国国家飓风中心称，该风暴预计于周五晚间或周六早间在美国墨西哥湾北部沿海登陆。
地图显示，伊萨亚斯预计将影响佛罗里达、阿拉巴马和佐治亚州部分区域，本周末至下周初将给沿海沿线以及美国东南部内陆地区带来中等至强降雨。
美国国家飓风中心表示，周三已为密西西比州海洋温泉市至佛罗里达州贝县/海湾县线以北的墨西哥湾北部沿海地区发布飓风预警；从路易斯安那州杰斐逊/普拉克明斯教区边界至海洋温泉市，以及从贝县/海湾县线至佛罗里达州奥奇洛克河区域则发布了热带风暴预警。密西西比河河口至佛罗里达州扬基敦区域同时发布了风暴潮预警。
自1905年以来首个生成时间最晚的首飓风
根据美国国家海洋和大气管理局的数据，伊萨亚斯于周四升级为飓风，这是111年来大西洋飓风季首个飓风生成的最晚日期，追平了1905年10月8日创下的纪录。
此次飓风季从6月1日持续至11月30日，今年迄今异常平静。
美国国家飓风中心根据1991年至2020年的气候数据计算得出，大西洋飓风季平均会形成14个命名风暴、7个飓风和3个强飓风。一个飓风季的首个命名风暴通常于6月中下旬形成，首个飓风一般在8月上旬至中旬生成，首个强飓风则多在8月下旬或9月上旬出现。
预报人员此前曾预测2026年大西洋风暴活动将低于平均水平，但截至目前该飓风季的平静程度超出预期。气象学家指出，这种沉寂局面主要源于夏季出现的强厄尔尼诺现象——该现象通常会导致大西洋海域水温降低、风场波动加剧，不利于热带系统发展。

Hurricane Isaias strengthened from a tropical storm late Wednesday night and is expected to make landfall along the U.S. Gulf Coast this weekend, threatening parts of Mississippi, Alabama and the western part of the Florida panhandle. It is the first hurricane of the 2026 Atlantic season.
Florida Gov. Ron DeSantis declared a state of emergency for more than two dozen counties in his state, which directed resources to prepare for potential severe impacts from the storm, while Alabama Gov. Kay Ivey issued a similar state of emergency for 40 counties.
Isaias had maximum sustained winds of 75 mph and was located about 460 miles southwest of the mouth of the Mississippi River, according to the National Hurricane Center.
Maps show hurricane’s path
Forecasters said they expected Hurricane Isaias, pronounced “ees-ah-EE-ahs,” to pass to the north of Mexico’s Yucatan Peninsula on Thursday before proceeding toward the Gulf Coast on Friday. It is forecast to make landfall along the northern Gulf Coast of the U.S. late Friday or early Saturday, the hurricane center said.
Maps show it is expected to impact parts of Florida, Alabama and Georgia, bringing moderate or substantial rainfall to stretches of the coast, as well as inland portions of the southeastern U.S., over the weekend and into next week.
A hurricane warning was issued Wednesday for the northern Gulf Coast, from Ocean Springs, Mississippi, to Florida’s Bay/Gulf county line, and a tropical storm warning was issued from Louisiana’s Jefferson/Plaquemines Parish line to Ocean Springs, and from the Bay/Gulf county line to Florida’s Aucilla River. A storm surge warning was also issued from the mouth of the Mississippi River to Yankeetown, Florida, according to the hurricane center.

The latest for a first hurricane since 1905
Isaias’ progression into a hurricane on Thursday marked the latest date in 111 years for the Atlantic season’s first hurricane to develop, tying a record set on Oct. 8, 1905, according to National Oceanic and Atmospheric Administration data.
The season, which has been unusually quiet this year, runs from June 1 through Nov. 30.
An Atlantic hurricane season produces 14 named storms, seven hurricanes and three major hurricanes, on average, according to the hurricane center, which used climate data collected between 1991 and 2020 to calculate those figures. A season’s first named storm normally forms in mid- to late-June, while the first hurricane tends to form in early- to mid-August, and the first major hurricane forms in late August or early September.
Forecasters predicted there would be less Atlantic storm activity than usual in 2026, but the outcome of the season so far has been even quieter than anticipated. Meteorologists have suggested the lack of action has been largely due to the onset of a strong El Niño over the summer, which typically correlates with cooler water temperatures and greater fluctuations in wind patterns over the Atlantic, conditions that dampen the growth of tropical systems.
