Hurricane Isaias, the first named hurricane of the 2026 Atlantic season, is moving toward the US Gulf coast near Alabama, threatening an area with significant refining assets and causing offshore oil and gas production shut-ins.

Landfall is expected Friday night or early Saturday along the Florida-Alabama border, according to the National Hurricane Center (NHC). The storm will be a strong Category 2 storm at landfall with sustained winds of up to 110 mph, according to AccuWeather.

The NHC issued a hurricane warning with heavy rain and winds of 74 mph or higher from Ocean Springs, Mississippi, to the borders of Bay County and Gulf County in Florida.

NHC also issued a tropical storm warning with winds between 39-73mph for a wider area stretching west to the Jefferson/Plaquemines parish borders in Louisiana and east to the Aucilla River in Florida.

Isaias is currently in the Gulf of Mexico about 170 miles north of Progreso, Mexico, with sustained winds of 85 mph with higher gusts, according to the NHC. Oil and gas producers in the Gulf of Mexico have evacuated workers and curbed output ahead of the storm.

As of 12:30pm ET Wednesday, about 512,000 b/d of US oil production, or 25pc of total offshore output, was offline, according to the Marine Minerals Administration. About 350mn cf/d of natural gas production, or 16pc of total US Gulf output, also was shut.

The onshore areas threatened by the storm includes several large oil refineries, such as Chevron's 356,000 b/d Pascagoula, Mississippi, plant, PBF Energy's 190,000 b/d Chalmette, Louisiana, refinery, Marathon's 617,000 b/d Garyville, Louisiana, refinery, Shell's 231,000 b/d Norco, Louisiana, refinery and Valero's 125,000 Meraux and 215,000 b/d St Charles facilities also in Louisiana.

Power outages and flooding could impact refinery operations at a time when US refiners are operating at levels above 90pc amid global fuel shortages caused by the wars in the Middle East and Russia.

The current NHC projected trajectory of Isaias would likely spare most of the refineries in Louisiana from the most severe hurricane impacts.
