Hurricane Isaias reaches Category 3 and closes on the Florida Panhandle

Hurricane Isaias strengthened to a Category 3 storm on Friday and was closing on the western Florida Panhandle, with landfall expected this evening. The National Hurricane Center's 4 p.m. CDT advisory placed the centre near latitude 29.2 north, longitude 87.0 west, about 90 miles south of Pensacola and 125 miles south-southeast of Mobile. Maximum sustained winds were 115 mph, or 185 km/h. The storm was moving north near 17 mph.

The centre said little change in strength was expected before landfall. After the centre crosses the coast, Isaias is forecast to weaken and become post-tropical on Saturday as it moves across Alabama into the Tennessee Valley. Hurricane-force winds extend outward up to 35 miles from the centre. Tropical-storm-force winds reach out to 205 miles.

A hurricane warning runs from Ocean Springs, Mississippi, to the Bay and Gulf County line in Florida. A tropical storm warning covers the coast west of Ocean Springs to the Jefferson and Plaquemines parish line in Louisiana, and eastward from the hurricane warning area. The centre warned of life-threatening storm surge and devastating winds along the Florida Panhandle and Alabama coasts. Surge of 6 to 9 feet is expected along the Alabama and Florida border, including Mobile Bay. Rainfall of 3 to 7 inches is forecast from southeastern Louisiana to the Florida Big Bend, with isolated totals of 15 inches possible.

Isaias is the first Atlantic hurricane of the 2026 season and the latest first hurricane in 121 years. The National Hurricane Center upgraded it to hurricane status late on 7 October after Air Force Reserve Hurricane Hunters measured hurricane-force winds. It intensified rapidly over record-warm Gulf waters. A 40 mph increase in intensity in the 24 hours ending early Thursday met the definition of rapid intensification. By Friday afternoon it was a major hurricane.

Earlier in the day the centre had the storm near 27.7 north, 87.3 west, about 170 nautical miles south of Pensacola, with a minimum central pressure of 959 millibars and maximum winds of 105 knots. Seas near the centre were running to 33 feet. Swells were already affecting the eastern Gulf coast from southwest Florida to Louisiana and were expected to produce large surf and life-threatening rip currents.

The forecast track takes the centre inland near the Alabama-Florida border, close to Pensacola, then north-northeast across Alabama on Saturday. Wind gusts of 70 to 90 mph are possible from Pensacola to Perdido Bay. Tornadoes may form on the northeastern side of the storm as it moves inland. Power cuts are expected to last for days in the hardest-hit areas.

The storm's late arrival ends a long quiet stretch in the Atlantic basin. The eastern Pacific has been more active, producing Hurricane Polo, described as the second most intense storm on record in that basin. Isaias developed over waters near 30 degrees Celsius and found an eddy of deep warm water that aided its final intensification. Models had disagreed on the peak. Some high-resolution runs kept it as a strong Category 2. Google's DeepMind model and the eventual observations put it at Category 3.

Residents in the warning area have been told to be in safe shelter by this evening. The centre's language in the 4 p.m. advisory was direct: conditions are deteriorating quickly within the storm surge and hurricane warning areas, and residents should be seeking safe shelter. Once the centre is inland the immediate wind threat falls, but the rainfall and the surge will continue to affect coastal and river communities through the weekend.
