Isaias strengthened into the first Atlantic hurricane of the 2026 season late Wednesday night, October 7. As of the 5 p.m. advisory on October 8, maximum sustained winds are 100 mph, and the storm is moving toward the northern Gulf Coast. In today's update, we will outline the expected impacts from the storm.
There have been no major changes to the forecast since yesterday's update. Isaias is expected to make landfall along the northern Gulf Coast, likely between the Mississippi-Alabama state line and the far western Florida Panhandle.
While the exact landfall point should not be the sole focus, it will help determine where the worst storm surge occurs, as the highest surge is typically to the right of the landfall location.
Isaias has remained relatively steady today and has not undergone the rapid intensification that was possible after it became a hurricane last night. The current top sustained winds are 100 mph and more strengthening is in the forecast with the NHC calling for a peak intensity of 110 mph.
Before landfall, some weakening is expected but Isaias will still be a strong Category 1 or Category 2 storm at landfall. It will also begin to undergo extratropical transition, meaning the storm will gradually take on some characteristics of a hybrid system. As this occurs, the wind field is expected to expand, allowing strong winds to extend farther from the center of the storm.
One slight difference from yesterday's outlook is an earlier landfall window. Landfall is now most likely Friday evening through early Saturday morning, probably in the hours between Friday 7 pm CDT to Saturday 1 am CDT. Looking more closely at the official forecast from the NHC, the storm is predicted to be just off the coast at 8 pm EDT/7 pm CDT Friday night:
As with most landfalling hurricanes, the main impacts from Isaias will be damaging winds, dangerous storm surge and high surf, heavy rain, and even the threat for tornadoes.
While the strongest winds will occur near the point of landfall, strong winds will spread well inland thanks to the speed of the storm and the extra-tropical transition. High wind warnings are also in place across Northern Alabama and Georgia. The red area below shows where hurricane-force winds are possible:
This includes Mobile and Pensacola, where winds from 74 to 110 mph are possible. Zooming out to the entire Southeast, wind gusts over 50 mph are possible as far north as northern Alabama and Georgia:
As noted above, the highest storm surge is expected just to the right of where the storm makes landfall. There is the potential for five to seven feet of storm surge. Locations east of the landfall point will generally see the greatest surge along the open Gulf coast, while areas west of landfall may experience significant surge along Mobile Bay and other bays and waterways. The peak storm surge forecast is in the image below:
In addition to the surge, wave heights will increase right up to landfall and the combination of the surge and wave action will cause more flooding. The below image shows wave heights approaching 30 feet by Friday evening:
Not surprisingly, the rip current risk for much of the Northern Gulf coast will remain elevated through the event:
The forecast for heavy rain is still on track and there are no big changes in the rain outlook. The Florida Panhandle will likely receive the heaviest rain with four to six inches of rainfall likely:
Within the four to six inches of rain expected in the Panhandle, there will likely be pockets of higher amounts, with some locations potentially topping out in double-digit rainfall totals. Outside of the Panhandle, the rest of the Southeast will likely receive two to four inches of rain.
One area we haven't discussed much yet this week is the Carolina Coast. A combination of moisture from Isaias and the Atlantic Ocean will also lead to heavy rain for this area, with three to six inches of rain possible:
The tornado threat will be an important part of the overall storm risk, as tropical tornadoes can develop quickly and with little warning. Friday's threat includes much of the Florida Panhandle:
The Friday threat will be concentrated from Friday evening into Saturday morning, making this an important period for situational awareness across the risk area. By Saturday, the threat for tornadoes moves into the Southeast:
This risk area includes the Florida Panhandle again but also stretches into Eastern Alabama and Georgia.
Isaias is expected to make landfall along the northern Gulf Coast Friday evening or early Saturday morning, with the greatest impacts from damaging winds, storm surge, heavy rain, flooding, and tornadoes. While the exact landfall location remains uncertain, the forecast has become increasingly focused on the area from the Mississippi-Alabama state line to the far western Florida Panhandle.
We will continue to monitor Isaias as it approaches the Gulf Coast and provide updates as the forecast evolves.
What is Hurricane Isaias?
Hurricane Isaias is the first Atlantic hurricane of the 2026 season. The storm was previously designated Invest 92L and Tropical Depression Nine before becoming Tropical Storm Isaias and strengthening into a hurricane.
2. When will Hurricane Isaias make landfall?
Hurricane Isaias is expected to make landfall along the northern Gulf Coast Friday evening through early Saturday morning, with the most likely window currently between Friday evening and early Saturday morning.
3. Where will Hurricane Isaias make landfall?
The exact landfall location remains uncertain, but the current forecast favors an area from near the Mississippi-Alabama state line to the far western Florida Panhandle, including the Mobile Bay region.
4. How strong will Hurricane Isaias be at landfall?
Isaias is expected to weaken somewhat before landfall, but the storm is forecast to remain a strong Category 1 or Category 2 hurricane. The National Hurricane Center's forecast calls for a peak intensity of 110 mph before some weakening occurs.
5. What impacts will Hurricane Isaias bring?
The primary threats include damaging winds, storm surge, high surf, large waves, heavy rainfall, flooding, and tornadoes. Strong winds are expected to extend well inland from the point of landfall.
6. How much rain will Hurricane Isaias bring?
The Florida Panhandle could receive four to six inches of rainfall, with locally higher amounts possible. Two to four inches are possible across other portions of the Southeast, while three to six inches are possible along portions of the Carolina coast.
7. Is Hurricane Isaias expected to cause flooding?
Yes. Heavy rainfall could produce flash flooding across portions of the Southeast. The Weather Prediction Center has a Level 3 out of 4 risk for excessive rainfall on Friday and a Level 2 out of 4 risk on Saturday in portions of the region.
8. Will Hurricane Isaias produce tornadoes?
Tornadoes are possible, particularly east of the storm's center and across portions of the Florida Panhandle, Alabama, and Georgia. Tropical tornadoes can develop quickly and with little warning.
