What happened
Tropical Storm Isaias formed near Progreso, Mexico, on October 7, 2026, with maximum sustained winds of 40 mph. The National Hurricane Center is tracking the system, which is expected to strengthen into a hurricane before hitting the US Gulf Coast. The storm is projected to bring heavy rain and dangerous wind and storm surge impacts to the northern Gulf Coast.
Why it matters
The storm's projected path includes critical energy assets, such as offshore oil rigs and major refineries. Chevron is evacuating nonessential personnel from its Gulf platforms as a precaution. Isaias is expected to become the first Atlantic hurricane of the 2026 season.
