气象监测人员正在追踪2026年大西洋飓风季首个潜在热带气旋，他们表示，该系统有可能在周三发展为完整风暴。
美国国家飓风中心于周二上午针对这一系统发布了初步天气预警，该系统目前是被称为“潜在热带气旋一号”的热带扰动。
此次预警发布之际，美国南部部分地区仍在遭遇创纪录降雨量和危及生命的山洪，当地社区正准备在本周剩余时间再迎接7至8英寸的额外降雨。
根据美国国家飓风中心的信息，潜在热带气旋一号于周二早些时候位于墨西哥湾西部，介于得克萨斯州科珀斯克里斯蒂和路易斯安那州查尔斯湖之间。它以每小时30英里的速度向东北方向移动，风速低于被归类为热带风暴所需的39英里每小时阈值。
截至最近一次更新，潜在热带气旋一号仍缺乏明确的中心，但气象预报人员表示，该系统可能会增强，并在周三达到热带风暴强度。无论是否达到这一强度，美国国家飓风中心都强调，该系统可能会给得克萨斯州东北部、路易斯安那州西南部以及阿拉巴马州和密西西比州部分沿海地区带来严重灾害。佛罗里达狭长地带的最西部区域也可能受到影响。
气象预报人员表示，危险的降雨和山洪是该潜在气旋的主要威胁，他们补充称，“严重的河流洪水”有可能发生，在部分地区，“持续降雨可能会使洪水威胁延续至周末”。
周二，美国国家飓风中心针对墨西哥湾西北海岸一段区域发布热带风暴预警，预警范围从得克萨斯州萨金特延伸至路易斯安那州摩根城，这意味着未来24至36小时内，该区域可能出现热带风暴级别的天气条件。
预报显示，包括达拉斯、休斯顿、圣安东尼奥和新奥尔良在内的多个主要城市可能会遭遇持续的强降雨天气，尤其是在未来48小时左右。气象学家预测部分地区每小时降雨量可达2至4英寸甚至更高，该地区已有超过4000万人处于各类洪水监视和预警之下。
在本周结束前仍面临洪水风险的多个地区此前已遭遇暴雨袭击。位于奥斯汀、圣安东尼奥和路易斯安那州什里夫波特的国家气象局办事处均报告称，当地周一出现创纪录降雨量，后两座城市单日降雨量达到了19世纪末以来的最高值。
根据国家气象局的数据，得克萨斯州首府奥斯汀打破了1964年创下的单日降雨纪录。

Forecasters are monitoring the potential first tropical cyclone of the 2026 Atlantic hurricane season, saying it could develop into a fully formed storm by Wednesday, they said.
The National Hurricane Center issued a preliminary weather advisory for the system, currently a tropical disturbance called Potential Tropical Cyclone One, on Tuesday morning.
It came as record rainfall and life-threatening flash floods continued to drench parts of the South, where communities braced for up to 7 or 8 inches of additional rain throughout the rest of the week.
Potential Tropical Cyclone One was located in the western Gulf early Tuesday, between Corpus Christi, Texas, and Lake Charles, Louisiana, according to the National Hurricane Center. It was traveling northeastward with winds of 30 mph, below the 39-mph threshold necessary to designate it a tropical storm.

The potential tropical cyclone also lacked a well-defined center as of the most recent update, although forecasters said the system will likely intensify and have tropical storm-force winds on Wednesday. Whether that happens or not, the National Hurricane Center emphasized the system could bring serious hazards to coastal sections of northeastern Texas and southwestern Louisiana, as well as parts of Alabama and Mississippi. Far-western portions of the Florida Panhandle could be affected, too.
Dangerous rainfall and flash flooding were the primary threats associated with the potential cyclone, forecasters said, adding that “significant river flooding” was possible and, in some spots, “prolonged rainfall may extend the flood threat into the weekend.”
A tropical storm watch was issued Tuesday for a stretch of the northwestern Gulf Coast, from Sargent, Texas, to Morgan City, Louisiana, which means tropical storm conditions could take shape there in the next 24 to 36 hours.
Several major cities, including Dallas, Houston, San Antonio and New Orleans, could experience ongoing spells of excessive rainfall, especially over the next 48 hours or so, forecasts showed. Various flood watches and warnings were in effect for more than 40 million people across the region, as meteorologists predicted some areas could see rainfall rates of 2 to 4 inches per hour, or higher.

Multiple places still vulnerable to flooding before the week’s end have already been battered by heavy rain. National Weather Service offices in Austin, San Antonio and Shreveport, Louisiana, each reported record rainfall in their cities on Monday, with the latter two receiving more rain in a single day than either had seen since the late 19th century.
Texas’ capital city broke a daily rainfall record set in 1964, according to the National Weather Service.
