Tropical Cyclone One could form off the Texas coast and cause dangerous flash floods

The United States has announced that a 'potential tropical cyclone one' has formed near the Texas coast. In a Tuesday warning, the National Hurricane Center warned of dangerous flash floods and heavy rain along the energy corridor which includes offshore drilling and refinery assets.

If it becomes stronger and the first named hurricane of the 2026 Atlantic Hurricane Season, the potential tropical cyclone Arthur -- located about 65 miles (105 kilometers) southwest of Corpus Christi - would be given the name Arthur. The maximum sustained wind speed is 30 miles per hour. Tropical storm watches have been issued along the northwestern Gulf Coast, from Sargent, Texas to Morgan City in Louisiana.

The NHC stated that the disturbance would move off the Texas coast either tonight or Wednesday morning, then move along the upper Texas coast later in the day. It will then move inland to extreme eastern Texas and southwestern Louisiana by late Wednesday or early early Thursday.

The storm system is expected to produce 4 to 8 inches in rainfall, with some isolated totals of up to 12 inches. This will occur along the Texas coastline through Louisiana and beyond. The NHC warned that a dangerous storm surge might 'flood areas normally dry.

On Monday, Governor Greg Abbott declared a state of disaster in 101 counties.

Heavy?rains may dampen the excitement surrounding the upcoming?FIFA World Cup game between Portugal and DR Congo, which will be played on Houston's streets on Wednesday. They could also have an impact on energy assets in the region. Earth Science Associates COO Tony Dupont said that so far the storm "doesn’t look too powerful."

Andrew Polk, weather risk manager for data consultancy DTN said that major oil production sites in the Gulf are outside the forecast track of tropical storm force wind.

He said that there may be disruptions due to the impact of helicopter operations, which could disrupt and delay the crew change due to winds and thunderstorms caused by Potential Tropical Cyclone One.

He continued by saying that "the wave impacts will primarily disrupt operations on the water with lift boats or scuba diving operations", adding that the main focus of the system would be the total rainfall amount expected along the Texas coast and Louisiana coastline.

In March, the federal offshore area of the U.S. Gulf of America produced approximately 2?million crude barrels per day. This accounted for 14% of U.S. total crude production. Shell, BP and Chevron are the biggest deepwater operators.

Around half of the total U.S. refinery capacity of 18,4?million barrels a day is located in the Gulf Coast region, which runs from Corpus Christi up to Mississippi River. The Motiva Enterprises Port Arthur, Texas plant owned by Saudi Aramco has a daily throughput of?730,000 barrels. The other major Gulf Coast refineries are Marathon Petroleum's Galveston Bay facility, ExxonMobil Beaumont, Baytown and ExxonMobil Baton Rouge.

Cheniere, Venture Global and other LNG giants have large liquefaction plants along the coast. Reporting by Ashitha Shivprasad from Bengaluru, and Sheila Dang from Houston; Writing and editing by Chizu Nomiyama & Aurora Ellis.
