A Tropical Storm Warning has been issued in parts of Texas and Louisiana as forecasters monitor a life-threatening system along the Gulf Coast.
The National Hurricane Center (NHC) said Potential Tropical Cyclone One was located about 35 miles southwest of Port O’Connor, Texas on Wednesday morning and moving northeast along the coast.
Forecasters expect the disturbance to strengthen as it tracks toward southwestern Louisiana, where it is expected to move inland later Wednesday.
The warning is in effect from Sabine Pass, Texas, to Morgan City, Louisiana, while a Tropical Storm Watch extends from Sargent, Texas, to Sabine Pass. Tropical storm conditions are expected in warning areas within the next 12 to 24 hours.
If the system reaches tropical storm strength, it would become Arthur, the first named storm of the 2026 Atlantic hurricane season to threaten the US Gulf Coast.
Meteorologist Dylan Federico with South Florida‘s WSVN News 7 said on X that ‘Arthur is coming,’ but noted that the storm will not become a hurricane.
The National Hurricane Center warned that the system’s greatest danger will be torrential rainfall, with widespread totals of five to 10 inches expected from Texas to Alabama and isolated areas receiving nearly 20 inches by early Friday.
The agency said the rainfall could trigger dangerous to life-threatening flash flooding across portions of Louisiana, Mississippi, Alabama, western Georgia and the Florida Panhandle.

The National Weather Service (NWS) said in a Wednesday morning alert: ‘Prepare: Efforts to protect property should now be underway.
‘Prepare for limited wind damage. Act now to complete preparations before the wind becomes hazardous.
‘Storm surge flooding preparations should be underway. Assemble disaster supplies and know your evacuation route.’
The agency added that locals should leave their homes if evacuation orders are given, saying: ‘Failure to heed evacuation orders may result in the loss of your life.’
Maximum sustained winds were near 30mph Wednesday morning, but forecasters said additional strengthening is possible before the system moves ashore.
The NHC currently gives the disturbance a 60 percent chance of becoming a named tropical storm within the next 48 hours.
Federico said on X: ‘For those of you [who] get stuck east of the center, Arthur’s rain bands will also produce strong tropical storm-force wind gusts of 40-60 MPH.
‘That can cause sporadic power outages, knock down trees/branches, and cause coastal flooding.’

The NWS said tropical-storm-force winds could begin affecting parts of the region Wednesday, with sustained winds of up to 40mph and gusts reaching 50mph in some areas.
Offshore waters are expected to experience hazardous conditions, with winds exceeding 46mph and seas building to as high as 11 feet.
Officials are particularly concerned about life-threatening storm surge along vulnerable coastal communities, as water levels could reach two to four feet above ground in surge-prone areas, creating the potential for widespread coastal flooding, beach erosion and dangerous rip currents.
Flood watches are in effect across portions of Louisiana, where additional rainfall totals of 1 to 4 inches are expected, with locally higher amounts possible.
The NWS warned that major flooding could trigger evacuations and water rescues, overwhelm rivers and drainage systems, and leave roads and bridges impassable. Streets and parking lots could quickly become flooded, creating hazardous travel conditions.
The system may also produce isolated tornadoes from Texas into Louisiana. While the tornado threat is currently considered limited, officials warned that even a few tornadoes could damage homes, uproot trees, disrupt power and communications, and complicate emergency response efforts.
Mariners have been urged to remain in port or seek safe harbor as tropical-storm-force winds and rough seas threaten to capsize or damage vessels and severely reduce visibility across coastal waters.
Emergency managers are advising residents to complete preparations immediately, monitor forecasts closely and be ready to act should conditions deteriorate or additional warnings be issued.
