How strong will Gulf tropical disturbance get? See Florida risks, timing

If the so-far-quiet 2026 Atlantic hurricane season has made you complacent, it may be waking up.

A disturbance in the Gulf has a high chance of developing this week and could become a tropical depression by the middle to later part of this week, according to the National Hurricane Center.

Regardless of strength, some rain and wind impacts can be expected in Florida from the system toward the end of the week and into the weekend.

As of Oct. 5, there have been no hurricanes and eight tropical storms in the Atlantic basin.

Here’s what is known at this time, although there is a great deal of uncertainty this far out.

Could we see a hurricane in the Gulf?

As of its 8 a.m. Oct. 5 seven-day forecast, the National Hurricane Center is saying a tropical depression is likely to form in the Gulf later this week.

“The most likely intensity is either a tropical depression or a tropical storm,” said Nick Arman, AccuWeather meteorologist of forecasting operations, via email Oct. 5.

“We currently believe there is a 15% chance of a hurricane strength storm from this area.”

Could tropical system in Gulf impact Florida?

“The eventual strength and track of any tropical system remain highly uncertain at this range, but it will be something to watch very closely over the coming days,” the National Weather Service Mobile said.

“Regardless of development, another period of widespread heavy rainfall appears increasingly possible, with gusty winds, dangerous surf, and coastal flooding also possible.”

When could Florida feel impacts from tropical system in Gulf?

For the United States, impacts would likely be from Friday (Oct. 9) through Sunday (Oct. 11) for the Gulf Coast, Arman said.

“Regardless of development, a surge of tropical moisture is likely to spread northward into much of the U.S. Gulf Coast which can lead to heavy rain and flooding late this week into the weekend.”

Where could tropical system go? Could there be a Florida landfall?

“With regards to where it might track, the most likely scenario is that it would track northward toward the northern Gulf Coast,” Arman said.

“However, there is still a wide variety of possible tracks depending on not only how quickly this development organizes, but also due to the influence of an upper-level low located over Texas.” Possibilities mentioned by Arman included:

If this moves north quickly and organizes, it will likely track somewhere between far eastern Texas and the Florida Panhandle.
If organization is slower, that would cause it to move farther westward toward the central Texas coast instead.
There is also the possibility that the upper-low does not pull the development northward quick enough, causing it to meander in the Gulf before moving back southward toward Mexico and the Bay of Campeche instead.

“As of now (Oct. 5), the least likely areas for this to track are toward both coastal Texas (south of Houston) and central and southern Florida due to climatology.

“However, they can’t be ruled out completely at this point. We definitely think that Florida is at risk for tropical rain and wind impacts, especially the Florida Panhandle. The most likely impact would be heavy tropical rainfall.”

Is rapid intensification possible with Gulf system?

“The waters in the Gulf are certainly very warm, which can support rapid intensification,” Arman said, “however, the wind shear over much of the Gulf is likely to limit how quickly this area can organize and intensify.

“The most likely intensity is either a tropical depression or a tropical storm. We currently believe there is a 15% chance of a hurricane strength storm from this area.”

National Hurricane Center tracking disturbance in Gulf showing potential for development

The National Hurricane Center’s 8 a.m. Oct. 5 advisory said a trough of low pressure in the southwestern Gulf of America is producing disorganized showers and thunderstorms.

Although environmental conditions appear to be marginally conducive, gradual development is becoming more likely, and a tropical depression is likely to form during the middle or latter portion of the week.

This system is expected to drift eastward over the next few days, before it turns northward.

What do the colored, hatched areas on the NHC map mean?

The hatched areas on the National Hurricane Center’s tropical outlook map indicate “areas where a tropical cyclone – which could be a tropical depression, tropical storm or hurricane – could develop,” said National Hurricane Center Deputy Director Jamie Rhome.

The colors make it visibly clear how likely a system could develop, with orange medium and red high. In 2026, the tropical outlook will use a gray X to indicate disturbances with a low chance for development.

The National Hurricane Center generally doesn’t issue tropical advisories until there is a named storm, but there is an exception.

“If a system is near land and there is potential for development, the National Hurricane Center won’t wait before it issues advisories, even if the system hasn’t become an actual storm. This gives residents time to prepare,” Rhome said.

What is a disturbance?

The National Hurricane Center’s tropical outlook map highlights “disturbances” in the Atlantic basin.

These are clusters of storms with some organization, but which don’t have a defined circulation typical of tropical cyclones.

If shown on the tropical outlook map in orange or red, forecasters are predicting the potential of those disturbances into developing as medium or high, respectively.

Disturbances shown on the map with a gray x have little to no chance for development. This is a change from prior years which indicated such disturbances in yellow.

When is hurricane season?

The Atlantic hurricane season runs from June 1 through Nov. 30.

Ninety-seven percent of tropical cyclone activity occurs during this time period, NOAA said.
