Florida on long-range alert for upcoming Gulf tropical threat
A new tropical threat will arise in the Gulf of Mexico and may threaten part of the southern United States in only about a week's time after Category 4 Hurricane Helene's deadly and destructive impacts.
Kevin Guthrie of the Florida Division of Emergency Management says power has returned for nearly the entire state after Hurricane Helene. They’re now bracing for another threat looming in the tropics.
The Gulf of Mexico remains the zone to watch for tropical development and impacts to the United States in the days ahead, and this time Florida may be the prime target for any budding system next week.
Last week, even as Helene was moving inland with deadly and destructive flooding, AccuWeather's long-range and hurricane experts pointed out that the next new threat to the U.S. would likely be from the Gulf of Mexico and the western Caribbean. That development zone is being narrowed down to the southern gulf, and the birth of a new storm could occur as early as this weekend or early next week.
AccuWeather meteorologists have labeled the Gulf threat as a high risk of development, just as they did for Helene.
"Water temperatures continue to remain warm in the wake of Helene over the southeastern Gulf of Mexico," AccuWeather Lead Hurricane Expert Alex DaSilva said. "Not only is the surface water warm, but it remains warm down deep so that wave action from any storm has little cooling effect."
The minimum water temperature for full tropical development is 78-80 F. Water temperatures in the southern Gulf of Mexico and northwestern Caribbean Sea remain well into the 80s.
But it takes more than warm water to spin up a tropical system. There needs to be an impetus for development, and disruptive breezes (wind shear) must be light.
Disorganized pockets of showers and thunderstorms will gather and grow in the waters surrounding southern Mexico and western Cuba in the coming days.
Tropical Depression 11-E formed in the eastern Pacific, just off the coast of Mexico, Tuesday afternoon. It is expected to become a tropical storm before making landfall in Mexico Wednesday afternoon. The next name on the eastern Pacific Hurricane list is Kristy.
If it were to move northward and survive into the southwestern gulf, it would retain the eastern Pacific name, but it is difficult for a storm's circulation to remain intact when crossing the mountains of Central America.
"Regardless, that energy is likely to spawn a development in the southwestern Gulf of Mexico from later this weekend to early next week," DaSilva said. "This seems like the bigger threat for more high-end development, such as a hurricane, as it would tend to spend more time, perhaps an extra two days or more, over the warm waters of the gulf."
AccuWeather Chief On-Air Meteorologist Bernie Rayno said that breezes next week would tend to guide any budding tropical feature to the eastern shores of the Gulf of Mexico rather than the central Gulf coast.
"This really looks like a threat of heavy rain and possibly a wind and surge threat, depending on storm strength, for Florida later next week," Rayno stated.
It is early yet, but interests in Florida, from the northeastern Gulf Coast to the Keys, as well as inland areas of the Sunshine State, should closely monitor the situation. Conditions may deteriorate from the middle to the latter part of next week with impacts from heavy rain and and possibly problems related to wind and storm surge.
Once confidence builds on the feature's starting point or a center is on the verge of forming, AccuWeather will likely declare a tropical rainstorm to begin issuing its own track maps.
At this early stage, a northward path into the far interior Southeast, including the Helene-devasted southern Appalachians, seems highly unlikely, but meteorologists will continue to monitor all aspects of the weather pattern closely.
Central Atlantic remains busy, with Kirk leading the show
Elsewhere in the Atlantic, Kirk, which formed in late September, is likely to strengthen rapidly and become a major hurricane of Category 3 strength or greater on the Saffir-Simpson Hurricane Wind scale.
"There is little to inhibit Kirk, and a high-end hurricane that is mostly a threat to central Atlantic shipping is forecast for mid- to late week," DaSilva said.
Because few obstacles are in its way, Kirk has the potential to last a long time. It could go on to impact part of western Europe, perhaps as a tropical wind and rainstorm, toward mid-October.
AccuWeather meteorologists are also watching for tropical development just north of the equator in the western Atlantic in the next few days. This feature is most likely to become a tropical storm and hurricane in the short term. There is also a low risk of tropical development off the coast of the Carolinas, near Bermuda.
The next names on the list of tropical storms and hurricanes for the 2024 Atlantic season are Leslie and Milton.
