Tropical Storm Isaias Path: Will Florida, Alabama or Mississippi Be Hit? Latest Forecast

Tropical Storm Isaias is strengthening in the Gulf of Mexico and could become the first hurricane of the 2026 Atlantic season, with Florida, Alabama, and Mississippi facing potential impacts as the storm approaches the northern Gulf Coast by late Friday or early Saturday.

The National Hurricane Center said Isaias had maximum sustained winds of 35 knots, or about 40 mph, with higher gusts as of Wednesday morning. Rapid strengthening is forecast over the next day or two, and Isaias is expected to become a hurricane by Thursday.

The latest NHC forecast shows Isaias moving northeast across the Gulf before reaching the northern Gulf Coast. The storm is forecast to be near 27.7N, 87.7W on Friday afternoon before moving inland near 30.8N, 87.7W on Saturday morning.

That projected path puts parts of the Florida Panhandle, Alabama and Mississippi within the broader threat area, although the exact location of the strongest impacts remains uncertain. The latest forecast also includes potential storm surge of up to 7 feet from Ocean Springs, Mississippi, to Indian Pass, Florida, including Mobile Bay, Alabama.

Will Tropical Storm Isaias hit Florida?

Florida is already preparing for potential impacts from Isaias. Gov. Ron DeSantis on Tuesday, Oct. 6, declared a state of emergency for 25 Florida counties as Tropical Depression Nine threatened the state. The system has since strengthened into Tropical Storm Isaias.

The counties covered by the emergency declaration include Bay, Escambia, Franklin, Gulf, Jackson, Jefferson, Leon, Liberty, Okaloosa, Santa Rosa, Walton and Washington, among others.

The Florida State Emergency Response Team has begun staging critical supplies in Tallahassee and the Santa Rosa area. The resources include generators, fuel, flood barriers, boxed water, shelf-stable meals, flood buckets, tarps, Tiger Dams and sandbags.

“Today, I signed an Executive Order issuing a state of emergency ahead of potential impacts from Tropical Depression 9,” DeSantis said. “This order will allow the Florida Division of Emergency Management to stage critical preparedness resources and ensure Florida is ready to respond.”

The governor urged residents to use the time before the storm arrives to prepare disaster plans and check their hurricane supply kits.

The Florida Panhandle remains within the broader potential impact area, although the NHC forecast does not establish a specific Florida landfall.

The forecast does not establish Florida as the definite landfall location, however. The storm’s final track could shift as Isaias strengthens and turns north toward the coast.

Could Alabama and Mississippi be hit by Isaias?

Alabama and Mississippi are also facing potential impacts as Isaias approaches the northern Gulf Coast. The latest NHC forecast shows the storm moving through the central Gulf before turning northeast and north toward the coast.

The storm surge threat extends across all three states. The latest forecast includes potential surge of up to 7 feet between Ocean Springs, Mississippi, and Indian Pass, Florida, including Mobile Bay, Alabama.

That does not mean Isaias will make a direct landfall in all three states. Instead, coastal areas of Mississippi, Alabama, and Florida could experience different levels of storm surge, strong winds, heavy rain and other impacts depending on the storm’s final track and intensity.

BMS Group senior meteorologist Andrew Siffert said the storm’s current track appeared to favor a landfall near Gulfport, Mississippi, while emphasizing that the exact track and intensity remained uncertain.

The NHC’s official forecast remains broader, with the storm expected to approach the U.S. northern Gulf Coast on Friday before moving inland.

How Strong Could Isaias Become?

Isaias is expected to strengthen rapidly over the Gulf of Mexico and become a hurricane by Thursday. The Gulf contains very warm water and high ocean heat content, which can provide substantial energy for tropical systems. The NHC said high oceanic heat content, moist mid-level conditions, and upper-level divergence should allow Isaias to intensify during the next several days.

However, the storm will also encounter increasing wind shear as it approaches the northern Gulf Coast.

Wind shear can disrupt a tropical cyclone’s structure and limit its ability to maintain maximum intensity. The NHC said southwesterly vertical wind shear is expected to strengthen later this week, making it likely that Isaias will reach peak strength before reaching the coast.

The latest forecast indicates a Category 2 hurricane is possible near landfall. Artemis reported that NHC forecast data showed sustained winds potentially reaching around 95 knots, or about 110 mph, before some weakening occurs ahead of landfall.

Because Isaias is expected to strengthen rapidly over warm Gulf waters, its intensity could change considerably during the next 24 to 48 hours.

Isaias Could Bring Dangerous Storm Surge and Flooding

Storm surge could become one of the most significant threats along the northern Gulf Coast.

The latest forecast calls for possible storm surge of up to 7 feet from Ocean Springs, Mississippi, to Indian Pass, Florida, including Mobile Bay, Alabama. Lower surge heights are expected along adjacent portions of the Gulf coastline.

Hurricane conditions are expected to begin along parts of the coast from late Friday, with tropical storm conditions possible earlier Friday.

Heavy rain is another major concern. Isaias could produce 3 to 6 inches of rainfall, with localized amounts reaching as high as 10 inches as the storm moves through.

Florida faces an added flooding concern because the Panhandle has recently experienced significant rainfall, leaving some areas saturated. Additional rainfall could increase the risk of flash flooding.

The storm’s rainfall and wind impacts are also expected to extend well away from its center, particularly to the east of the storm’s track.

Could Isaias Produce Tornadoes?

The storm could also generate tornadoes as it approaches the Gulf Coast and moves inland.

A BMS Group meteorologist warned that a significant tornado threat could develop east of the storm’s track, including after landfall. The exact location of that threat will depend on where Isaias comes ashore and how its structure evolves.

This is particularly important because a tropical cyclone does not need to make a direct landfall in an area for dangerous weather to occur there.

Strong winds, heavy rainfall, storm surge, and tornadoes can affect areas well away from the center of a tropical system.

Where Will Isaias Go After Landfall?

The NHC expects Isaias to move inland across the Southeast after reaching the northern Gulf Coast.

The storm is expected to move northeast across the Gulf on Thursday before turning northward and reaching the northern Gulf Coast on Friday. It is then expected to weaken as it moves farther inland, with the NHC forecast showing Isaias weakening to a tropical depression early Sunday.

The exact track remains subject to change because Isaias is expected to strengthen rapidly before encountering stronger wind shear near the coast.

What Residents in Florida, Alabama and Mississippi Should Know

Florida, Alabama and Mississippi are all within the broader area that could experience impacts from Isaias, but the threat will not necessarily be the same across the three states.

Florida’s Panhandle is within the potential landfall and storm surge threat area, while Mobile Bay in Alabama and Ocean Springs in Mississippi are specifically included in the latest storm surge forecast.

The storm’s strongest effects will depend on its final track, size, and intensity. Residents along the northern Gulf Coast should continue following updates from the National Hurricane Center and local emergency officials as the forecast evolves. Isaias is expected to become the first hurricane of the 2026 Atlantic season if it reaches hurricane strength.
