Hurricane Isaias Forces Oil Industry Preparations as Storm Approaches Gulf Coast

Hurricane Isaias, the first named storm of the Atlantic season, intensified to a Category 2 system on Thursday as it moved through warm Gulf of Mexico waters toward the southern United States. According to the National Hurricane Center, the storm is forecast to make landfall along the Florida Panhandle, Alabama, or Mississippi coast overnight Friday into Saturday.

In response, energy companies operating along the U.S. Gulf Coast have initiated preparatory measures. While the majority of the nation’s oil infrastructure is located further west in Louisiana and Texas, a significant segment operates in the region threatened by the storm.

Major companies including Shell and BP have evacuated staff from deepwater platforms near the storm’s projected path. Chevron has similarly pulled workers from offshore drilling rigs close to Isaias and plans to redeploy them once the weather system passes. An Exxon spokesperson told NPR that the company is closely monitoring conditions but that operations remain normal.

Experts suggest the storm may cause fewer disruptions than initially feared because its trajectory is shifting eastward, away from the densest concentration of refineries and production facilities.

“The storm’s path could be worse,” said Debnil Chowdhury, head of Americas refining at S&P Global Energy. He noted that Isaias is making a sweeping turn just to the east of the area’s most critical infrastructure.

Bryan Domangue, Gulf of America region director for the federal Marine Minerals Administration, confirmed that the storm is tracking just south of major deepwater oil and gas facilities while hugging their eastern boundary. In addition to personnel evacuations, which are standard protocol, operators are closing subsurface safety valves and relocating mobile drilling units where feasible.

While the industry has faced devastating hurricanes before—notably Katrina and Rita in 2005, which destroyed dozens of platforms—more recent storms like Harvey, Ida, and Francine primarily resulted in temporary production halts rather than catastrophic infrastructure loss.

The greater concern among analysts is the potential impact on land-based refineries. If Isaias damages power grids or causes flooding, restarting these complex facilities can be time-consuming.

“Restarting these things is like starting up an old car,” said Carl Larry, a manager at energy research firm Enverus. He explained that refineries operate on a continuous 24/7 cycle to break down crude oil into diesel, gasoline, and propane. If power is lost, the entire process must be slowly rebuilt.

Two major refineries sit in Isaias’s potential path: the Chevron facility in Pascagoula and the Vertex refinery in Alabama. While their representatives did not comment on specific preparations, Chevron spokesperson Ross Allen stated that facilities generally focus on mitigating flood risks before storms arrive.

Chowdhury noted that these two plants account for approximately 2.5% of total U.S. refining capacity and about 5% of Gulf Coast capacity, with the Pascagoula site being particularly vital for supplying aviation fuel to the Southeast.

Although these percentages seem modest, they carry weight given the current tight global supply of diesel and gasoline, exacerbated by conflicts in Iran and Ukraine. American refineries are currently operating at 92.7% capacity, processing roughly 17 million barrels of crude daily.

With the midterm elections approaching, fuel costs remain a politically sensitive topic. According to AAA, the national average for a gallon of gasoline is $4.37, while diesel averages $6.27.
