Isaias strengthens as Gulf Coast landfall threat grows

Hurricane Isaias strengthened over the Gulf of Mexico on Thursday, October 8, with the National Hurricane Center forecasting a possible northern Gulf Coast landfall late Friday or early Saturday, October 9-10. The storm’s track and strength remained uncertain, but forecasts warned of storm surge, heavy rain and possible tornadoes in threatened areas. The center upgraded Isaias late Wednesday, October 7, after reconnaissance aircraft measured sustained winds of 75 mph. By Thursday, winds had reached 80 mph, according to the center. Isaias was the first Atlantic hurricane of the 2026 season and, according to the evidence available from reliable tracking, the latest first hurricane since satellite tracking began. Earlier storms may have gone undetected before that tracking era. The center’s forecast placed potential landfall within the northern Gulf warning area, but did not establish a precise location or eventual intensity. A Thursday forecast cited a possible storm surge of 5 to 7 feet, rainfall of up to 10 inches in some places and isolated tornadoes. Those were projected hazards, not reported impacts.
