# Hurricane Isaias causes fatalities and energy disruptions > Live situation record from CLSTR: https://clstr.news/situations/hurricane-isaias-gulf-coast-landfall > Updated: 2026-10-09T20:18:48.000Z. Sources: 192. Developments: 4. Hurricane Isaias, the first hurricane of the 2026 Atlantic season, struck the southern United States as a major Category 3 cyclone before weakening. The storm made landfall near Destin, Florida, as a Category 2 hurricane with sustained winds of approximately 105 mph (165 km/h). This late-season landfall is attributed in part to El Niño and coincided with a rare meteorological event where tropical systems simultaneously threatened both the U.S. East and West coasts, a scale of occurrence not seen since 1963. The hurricane caused at least four confirmed fatalities: two in Alabama and two in Florida. The Florida deaths were attributed to a tree falling on a home and a carbon monoxide poisoning incident involving a generator in a garage. In Alabama, one of the fatalities involved a vehicle crash caused by a downed tree. Infrastructure damage is widespread, with hundreds of thousands of customers across Florida, Alabama, Georgia, and Mississippi experiencing power outages; some reports indicate nearly one million households have been affected. The storm also brought life-threatening storm surges, heavy rainfall, and flash flooding risks across several states, including Louisiana, Mississippi, Tennessee, and the Carolinas. The energy sector faced severe disruption as the evacuation of offshore platforms in the Gulf of Mexico temporarily halted approximately 71 percent of oil production in the U.S. sector, removing an estimated 1.3 to 1.5 million barrels per day from the market. To mitigate supply chain disruptions, the U.S. Department of Energy announced the release of 4 million barrels of oil from the strategic petroleum reserves. Emergency measures, including state-of-emergency declarations and the mobilization of approximately 5,000 National Guard members in Florida, remain underway to manage the aftermath and ongoing flood risks. ## Claims - Hurricane Isaias made landfall near Destin, Florida, as a Category 2 storm.
