After one of the strangest hurricane seasons in modern history, the Atlantic finally has its first hurricane. And Isaias is making up for lost time.
Hurricane Isaias strengthened late Wednesday over the Gulf, becoming the first hurricane of the 2026 Atlantic season more than four months after the season officially began. The delay is extraordinary: 2026 had already become the longest hurricane-free Atlantic season of the satellite era, with the previous benchmark for such a late first hurricane dating back to October 1905.
Check out the show the storm put on from space, linked here, and below.
As of early Thursday, the National Hurricane Center placed Isaias about 445 miles south-southwest of the Mississippi River’s mouth, with sustained winds of 75 mph, moving east-northeast at 9 mph.
“Additional intensification is expected,” the NHC warned, with Isaias forecast to remain a strong hurricane as it approaches the northern Gulf Coast Friday night.
The satellite imagery makes the storm look especially ominous.
Lightning flashes can be seen flickering through the storm’s sprawling thunderheads as the cyclone organizes. Lightning isn’t necessarily unusual in hurricane rainbands, but NOAA notes that bursts near a hurricane’s inner core can sometimes accompany changes in intensity and powerful convective development.
Then there are the waves.

NOAA reported peak seas near 20 feet early Thursday, but its high-seas forecast has significant wave heights building to approximately 30 feet within 24 hours and 33 feet within 48 hours near the hurricane. Critically, NOAA notes that individual waves “may be more than twice” the significant wave height.
Some are claiming even bigger in the Gulf. See the forecast, linked here, below.
Translation: the viral warnings of 25-to-50-foot waves in the Gulf aren’t as far-fetched as they sound, particularly close to the storm’s core.
On land, Isaias may be even more dangerous.
The NHC forecasts 3 to 7 inches of rain, with isolated totals up to 10 inches, from southeastern Louisiana through the Florida Panhandle, along with flash flooding, storm surge, tornadoes, and “life-threatening surf and rip current conditions.”
Perhaps the strangest part is why it took so long.
A powerful El Niño has spent much of 2026 producing hostile wind shear across the Atlantic, essentially ripping developing hurricanes apart. Isaias finally found a brief window of lighter shear and extremely warm Gulf water.
The Atlantic waited four months for its first hurricane.
Now it has everyone’s attention.
