Tropical Storm Isaias heads toward Gulf Coast, could become hurricane as Florida declares emergency: All you need to know

Tropical Storm Isaias has formed in the Gulf of Mexico and is expected to strengthen into a hurricane by Thursday or early Friday, according to the US National Hurricane Center (NHC). The storm formed on the morning of October 7, 2026, after a depression strengthened over the warm waters of the Gulf. As of Wednesday, Isaias was about 580 miles (935 km) southwest of the mouth of the Mississippi River, with maximum sustained winds of 40 mph (65 km/h). As per reports, Isaias may strengthen rapidly due to favourable conditions including very warm Gulf waters and relatively light wind shear.

Florida Governor Ron DeSantis has meanwhile declared a state of emergency in 25 counties as the storm moves toward the northern Gulf Coast. DeSantis said the emergency declaration would give communities additional time and resources to prepare for possible impacts.

“This order ensures communities have the time and resources necessary to prepare for potential severe weather impacts to the Panhandle and Big Bend region of Florida,” DeSantis said.


The NHC has also warned that hurricane and storm surge watches could be issued soon.

Could Isaias become the first hurricane of 2026?

Isaias could become the first hurricane of the 2026 Atlantic hurricane season if it reaches hurricane strength by October 8, News 6 reported. If Isaias becomes a hurricane on October 8, the report added, it would tie the record for the latest first hurricane of an Atlantic season, set on October 8, 1905.

Where could Isaias make landfall?

The storm's exact path remains uncertain. Current projections indicate that Isaias could make landfall somewhere between eastern Louisiana and the western Florida Panhandle. The uncertainty means residents along the northern Gulf Coast, particularly in areas of Louisiana and Florida, are being urged to closely monitor forecasts and prepare for potentially severe weather.

Heavy rain, flooding and tornado threat

Due to Isaias, heavy rainfall is expected in the region. Some areas could receive 3 to 6 inches of rain, while isolated locations could see as much as 10 inches. Rain could begin affecting parts of the Gulf Coast as early as Friday and continue into the weekend. The storm could also bring coastal flooding, strong winds and tornadoes as its rainbands move across the region.

The NHC said the storm's exact track remained uncertain but warned that Isaias could approach the Gulf Coast late this week.
