2026 Atlantic Hurricane Season

[TheDreamTraveler]

Every day is just another record broken for no hurricane formation which is just nutty honestly. Like normally when you beat records like this it's only maybe a few days but we're entering 5 days now since we broke the record back on September 11th. We do have that area of interest at 40% but I'm still not fully convinced it ends up developing into much of anything let alone a hurricane. But if it can take advantage of the good conditions that will be available in that small area of the Atlantic it could have a chance to spin up into something reasonable. Actually I was just checking that area of interest while writing this post just now and NHC went back down to 30% now lol

This is the most Niño Niño that ever Niño’d.

I think the latest date ever recorded for the formation of a hurricane since maritime shipping logs occurred in 1941. That date is September 17th. That record is toast.

While not calling for a September hurricane shutout at this point the lack of a hurricane for the 2026 season could easily go on for another week.  Pretty amazing honestly.  We almost made it with Edouard.  A track a little further offshore before landfall would have easily done it.  It was very close but no cigar.

What’s this on the 12Z UKMET? For the first time, it has a TC (TD) in the C Gulf late in the run with it moving slowly WNW and strengthening:

NEW TROPICAL CYCLONE FORECAST TO DEVELOP AFTER 150 HOURS

After having a central Gulf TD late on yesterday’s 12Z per the quoted post and then not on the 0Z, today’s 12Z UKMET at the identical time (18Z on 9/21) has a TD form albeit in the E Gulf rather than C Gulf and with it moving very slowly WNW just like yesterday’s run had:

Worth noting that despite the lower odds, Invest 98L has seen an uptick in support from ensemble guidance. I've always thought this one had a chance in this region, and tonight we're seeing a flare up of convection near the center. We'll see if that continues. 

Currently it is meandering into a region of significantly lower shear and warmer SSTs. Just enough of a window for something to pop...

Lol at tonight's GFS 00z operational. I made a post during the previous week that modeling of any potential CAG system was going to be rather chaotic until something actually resolved. That has definitely been the case. Still, if something develops and gets in the right position at the right time, potential exists for a powerful system given the potential favorable upper environment that should evolve over the GOM next week. If nothing else, it's something to watch. Mind you, though the UKMet and GFS suites continue flirting with a system, the Euro suites haven't been bothered yet. I should add it's not that Euro doesn't have the CAG there, it just transfers that energy or resulting vorticity into the EPAC instead of trying to resolve something in the WCARIB or GOM.

The off again, on again UKMET is now off again with a Gulf TC fwiw.

 Despite the Euro having something in the Gulf late, ironically the crazy GFS has no Gulf TC on its 6Z for the 1st run since way back at 18Z of 9/14! It just has one moving just N of Cuba (not in Gulf) at 384.

It still does have a system / vorticity breaking off of the CAG 130'ish hours into the 6Z run, it just fails to develop a fully fledged TC and bring that into the GOM. That could just as easily come back on the 12z today. Again, chaotic. Though, yes, it also breaks off vorticity and develops a hurricane late in the run. Meh, these simulations will remain complete choas until something actually resolves. If anything can be taken from these runs at this point, it's to say we should have a warbling surface trough gyre establish itself by this weekend over central America and we just need to watch for any pieces of energy and vorticity that may break off on either side of the landmass (EPAC or WCARIB) for potential development over the next few weeks.

The MJO is heading toward favorable phases for TCG at this time of year, which Joe Bastardi has been appropriately emphasizing in his call for activity:

Any idea what the record is for longest streak without a TC in the Atlantic in September?

I think it was last year, we didn't have a TC from August 28-September 16.

[The year before, we didn't have a TC from August 21-September 8.]

If you live in Fla, don't look at the GFS 12z. lol

12Z UKMET: again says no Gulf TC
