FLHurricane.com: Fiona, Gaston and 98L. Atlantic Switched On.

11:45PM EDT 21 September 2022 Update

It can not be overstated just how much of a 180 the Atlantic basin has made, and many land-based locations are now at continued or increasing risk of serious impacts. With the addition of 99L and basically a "landphoon" rolling off westernmost Africa, there are now two active named tropical cyclones plus three almost tropical cyclones out there.

Recon has just completed a survey of the environment over the Caribbean in the immediate vicinity of Invest 98L, which is now 90% odds of becoming a numbered tropical cyclone within 5 days. The data collected by this mission will be invaluable in modeling and forecasts. There are factors that could delay organization, but probably only delay. There are other factors that could steer it away from the northern Gulf of Mexico, but at present, models are continuing to sniff out a western Caribbean to Gulf coastal states threat in the mid/long-range (Please see 98L Forecast Lounge for more on this).

The next three names on the list in the 2022 season are: Hermine, Ian and Julia.

8PM EDT 21 September 2022 Update
Category 4 Hurricane Fiona is starting to move faster to the North and should be near Bermuda late tomorrow night into Friday morning, and then head up to Atlantic Canada as an , but extremely powerful storm. It should landfall near the eastern end of Nova Scotia on Saturday morning.

Gaston is moving generally slowly and will get near the Azores sometime Saturday before moving back east on the forecast and becoming .

98L is likely to remain disorganized for another few days until it gets west of the ABC islands, but remains something that should be watched closely for those in the Cayman Islands, Western Cuba, Yucatan Peninsula, and Central Gulf as well as Florida into next week. There is a great deal of uncertainty after 5 days or so. Recon is out sampling the area tonight to hopefully improve the modeling on this system in the near future.

Two other areas, one has a 60% chance for development offshore of Africa, and another in the east central Atlantic with a 30% chance for development.

8AM EDT 21 September 2022 Update
The season is making up for a extended slow start. Fiona looks like it'll pass west of Bermuda enough to not cause too many problems, however Nova Scotia in Canada is going to get hit by a system turning into more of a hybrid noreaster but with the pressure and power of a category 4 hurricane.

The Turks and Caicos got hit pretty hard yesterday, particularly Grand Turk.

98L is now up to a 90% chance for development and this is the one we need to watch in Florida, particularly late next week (Thursday-Saturday) still too far out to say exactly what will happen, but all of Florida to about coastal Mississippi should monitor it closely. It has not developed yet, but likely will in 2-3 days. The Windward islands of the Caribbean will be impacted first, but mostly by rain and squalls before moving into the Caribbean. It will likely not develop until in the Caribbean sea itself.

Gaston is still moving in the north Atlantic, the Azores should monitor it. Two other areas, one off Africa has a 50% chance for development, but will likely stay away from land, and another in the Central Atlantic with a 30% chance to develop.

8PM EDT 20 September 2022 Update
Busy day in the Atlantic Tropics. Gaston has formed from 97L, but it is likely to stay out to sea, however it may get very close to the Azores. So folks in those islands should watch it closely.

Fiona is moving away from the Turks and Caicos, and likely to stay west of Bermuda, however it's increasingly likely it may reach Nova Scotia in Canada as a very powerful hurricane or storm.

98L is the system east of the Caribbean that the windward islands should watch, it is now up to a 90% chance to develop over the next 5 days. This storm should be watched by most of the Caribbean, Yucatan Peninsula, Florida and the Central Gulf coasts closely into next week.

Another area off Africa has a 40% chance to develop, those in the Cape/Cabo Verde islands should monitor that.

5PM 20 September 2022 Update
TD#8 has been upgraded to Tropical Storm Gaston, and already looks to be ramping up even more quickly from there.

Original Update

The Atlantic basin is on track for another serious season, even if total numbers come in below forecasts.

After producing Harvey-like catastrophic flooding in Puerto Rico and portions of the Dominican Republic, Hurricane Fiona moved back out over open water, resumed intensifying, and became 2022's first Major. Major Hurricane Fiona is now impacting the eastern Bahamas early this week, before likely whacking Bermuda with the stronger eastern semicircle (with perhaps a direct hit), and then probably move on to striking Nova Scotia as a violent hurricane-force storm, either post-tropical or not.

Invest 97L in the subtropical Atlantic became TD 8 this morning. Interests in the Azores may want to monitor this cyclone.

Our attention has quickly returned to the region just east of the Caribbean, where another stout tropical wave, 98L, now has high odds of becoming our next named storm and potential significant hurricane, and this time probably with a track that takes it further west than Fiona, with models largely already sniffing out risks from the Caribbean to the Gulf.

The next two names on the list in the Atlantic this year are Gaston and Hermine.
