It’s happening again.
Potential Tropical Cyclone Nine, soon-to-be Helene, is likely to become yet another Florida Gulf Coast hurricane landfall within a matter of days. While there remains uncertainty in both the track and intensity forecast, Florida isn’t getting out of this one.
Governor Ron DeSantis issued Executive Order (EO) 24-208, Emergency Management – Potential Tropical Cyclone Nine, declaring a state of emergency in 41 Florida counties ahead of the storm.
More damaging and less damaging outcomes are possible but know that the Panhandle, Big Bend, and west-central Florida coasts are at serious risk of surge, wind, and rain impacts from a potential major hurricane landfall Thursday or Friday.
With some of the storm models painting truly scary scenarios, preparations to secure life and property should start now for these areas. Consider this your fire alarm.
Florida threat level increasing for soon-to-be Helene
As of mid-day Monday, the National Hurricane Center has begun issuing advisories on Potential Tropical Cyclone Nine, located just south of the Caymen Islands western Caribbean Sea.
For now, this system is a “potential tropical cyclone” rather than a tropical depression or storm because it does not yet have a well-organized surface circulation, but that could happen at any point. Hurricane watches are in effect for the northwestern Caribbean, and will likely be required for portions of Florida on Tuesday.
With the potential storm still consolidating and entangled for another day with a broader Central American Gyre, a movement to the west or west-northwest is expected through Tuesday, followed by a turn north through the Yucatan Channel on Wednesday morning, by which point future Helene should be at or nearing hurricane intensity as it enters the southern Gulf of Mexico.
Several key developments over the weekend have winnowed away some of the less threatening possibilities for how Helene plays out and increased the severity of the Florida threat.
The storm has organized on the quicker side of the possibilities, giving it more time to develop and strengthen before landfall. The system’s circulation is also coming together fully over water and should shoot the gap between the Yucatan peninsula the western Cuba, so land interaction is not going to tap the brakes either.
Instead, future Helene has about three and a half days to develop a core of deep convection and take advantage of a favorable thermodynamic and atmospheric environment for strengthening, which sets it up for potential rapid intensification on approach to Florida.
