Hurricane Isaias Breaks Quiet 2026 Atlantic Season, First Hurricane of the Year

Hurricane Isaias became the first Atlantic hurricane of 2026 on Oct. 7, breaking a record‑quiet start that had seen no storms since the season’s beginning. The storm formed in the western Gulf of Mexico, where a temporary drop in vertical wind shear and a pocket of moist air allowed it to organize rapidly over exceptionally warm waters. Earlier in the year, a strong El Niño had increased wind shear and dry air across the tropical Atlantic, suppressing hurricane development and keeping most storms confined to higher latitudes. Isaias is expected to make landfall on the northern Gulf Coast late Oct. 9 or early Oct. 10, prompting residents in Alabama and the Florida Panhandle to board up windows and deploy sandbags, and the Tyndall Air Force Base to evacuate fighter jets. The event underscores that a slow start does not guarantee a quiet season, as atmospheric conditions can shift dramatically in October.
