This is how the first Atlantic cyclone that threatens the southern coast of the United States advances.

The Tropical Storm Arthur, The first cyclone of the 2026 Atlantic hurricane season threatens the southern coast of USAmainly Texas and Louisiana, with intense rains, strong winds and potentially deadly flash floods, reported the National Hurricane Center (NHC, in English).

The system formed in the Gulf of Mexico and was located near the Texas coast, with maximum sustained winds of 75 km/h and moving towards the north-northeast at 11 km/h. Its tropical storm-force winds extended up to 280 kilometers from the center, according to the most recent NHC bulletin.

Arthur maintains a tropical storm warning between Sargent, Texas, and Morgan City, Louisiana. Although it is expected to weaken as it moves inland, its rains could extend the threat of flooding into Louisiana, Mississippi, Alabama, northwest Florida and Georgia.

States under threat from Arthur

The areas most at risk are Texas and Louisiana, where heavy rain, coastal flooding, strong winds and dangerous waves are expected. There is also a flash flood watch in Mississippi, Alabama, Georgia and the Florida Panhandle.

The NHC warned that rainfall could accumulate between 12.5 and 25 centimeters, with isolated maximums of up to 50 centimeters. In some areas, rainfall rates could reach 5 to 10 centimeters per hour, increasing the risk of rapid flooding and road blockages.

Waves, storm surge and possible tornadoes

In addition to rain, Arthur generates storm surge, rip currents and dangerous surf on the northwest coast of the Gulf of Mexico. The authorities also maintain surveillance for possible isolated tornadoes in coastal areas and areas under the influence of the system.

In sectors between Port Bolivar, Texas, and Morgan City, Louisiana, moderate coastal flooding is expected that could affect roads, low-lying areas and communities near the coast.

Arthur was formed when parts of Texas were already experiencing heavy rain and flooding. In Montgomery County, near Houston, a 15-year-old boy died after falling into a retention pond while playing near a construction zone, according to local authorities.

In Mississippi, the city of Picayune declared a state of emergency after heavy rains that left almost 18 centimeters of water in six hours. The authorities distributed sandbags and put emergency services on alert.

First Atlantic storm of 2026

Arthur is the first named storm of the Atlantic hurricane season, which began June 1 and ends Nov. 30. NOAA predicted up to 14 named storms and six hurricanes in the Atlantic this year.

Authorities asked residents and tourists in areas under warning to stay alert to official bulletins, avoid flooded areas, not cross roads covered in water and follow local emergency instructions.
