The National Hurricane Center (NHC) announced Tuesday that the disturbance in the southwestern Gulf of Mexico has strengthened into Tropical Depression Nine, forecast to become Tropical Storm Isaias (ees-ah-EE-ahs) on Wednesday and a hurricane on Thursday — the first hurricane of the 2026 Atlantic season. It is expected to reach Category 2 strength (about 100 mph winds) by Friday night and make landfall somewhere between Louisiana and the Florida Panhandle over the weekend. The forecast track crosses waters producing 15% of U.S. crude oil, and energy markets are already on edge.
The depression formed in the Bay of Campeche in the southwestern Gulf, with maximum sustained winds of 35 mph, centered about 630 miles southwest of the Louisiana coast. Once winds reach 39 mph it will earn the name Isaias, the ninth named storm of the 2026 Atlantic season. Hurricane hunter aircraft flew into the system Tuesday afternoon to gather data, with the first low-level reconnaissance flight scheduled for Wednesday.
The forecast track takes the system eastward at first, then north toward the U.S. Gulf Coast: passing north of the Yucatan Peninsula on Thursday and approaching the northern Gulf Coast on Friday, reaching Category 2 strength Friday night. The NHC warned it is expected to be "a dangerous hurricane when it makes landfall," likely late Friday or Saturday. NOAA's Weather Prediction Center has issued a Level 2-out-of-4 flash flood risk for parts of the Southeast for Friday and Saturday.
This year's Atlantic season has been smothered by El Niño — in the modern record dating to about World War II, no season has ever gone this late into October without producing a hurricane. Meanwhile Gulf waters are at their warmest on record for this time of year, dating back to 1982, priming the system to strengthen. "If the storm is farther east, I think it can escape a lot of wind shear and you could end up with a hurricane," said AccuWeather lead hurricane forecaster Alex DaSilva. "If it's in the central Gulf, you are probably looking at a tropical storm."
Beyond traditional models, AI forecasting is leaning bullish. Meteorologist Michael Lowry noted that Google DeepMind's ensemble — one of the best-performing models of the 2025 hurricane season — has 80% of its members reaching hurricane strength. "We should be a little wary of DeepMind's intensity guidance before we have a defined depression or storm," Lowry said, "but it's a noticeable uptick from earlier cycles."
Reuters reports the forecast track passes through offshore Gulf areas producing 15% of U.S. crude oil and 5% of the country's natural gas. Six refineries sit in the potential landfall zone, operated by Shell, Valero Energy, Marathon, PBF Energy, and Chevron. Refineries in the Gulf states account for about 50% of national capacity of 18.2 million barrels per day. Any significant impact could further tighten energy markets and drive up gasoline and diesel prices already soaring amid the U.S.-Israeli war with Iran.
The exact landfall point and intensity remain uncertain, and forecasters stress that anyone from Louisiana to Florida's Big Bend should monitor updates closely. Whatever its final strength, heavy rain is a near certainty: the system will track quickly north, bringing flooding rain, powerful winds, and storm surge from southern Louisiana to the Florida Panhandle.
