2025 Atlantic Hurricane Season

[WxWatcher007]

I don’t see anything possible other than homebrew/hybrid off the east coast in the next week or so.

Interesting write-up about google's deepmind model, and how it did for erin: https://arstechnica.com/science/2025/08/googles-ai-model-just-nailed-the-forecast-for-the-strongest-atlantic-storm-this-year/

Told you DeepMinds is the way to go

 Today’s Euro Weekly run not only has the most active 9/15-21 ACE yet, it is the 1st run with 9/22-8 and that is even more active than 9/15-21! It has the quietest Sep week as the 1st one and the noisiest week as the 4th one. That resembles Sep of 2024 somewhat because then the quietest weeks of ACE in Sep were the 1st (0) and 3rd (0) while the 4th had the noisiest by far with AN ACE (18.1). The 2nd had 6.1.

Today’s EW ACE Sep progs vs very active 20 yr climo
1-7: 4.5 (.3)
8-14: 11.3 (.7)
15-21: 20.4 (1.3)
22-28: 22.4 (1.6)

 So, today’s vs climo is despite a very quiet 1st week and still BN 2nd week progging the 1st 4 weeks of Sept at 58.6, which compares to only 24.2 in 2024 and is ~the active 30 year climo of ~60.

To compare, look at what I posted on 8/27/24:

Today’s Euro Weeklies could be nicknamed “A Tale of Two Seasons”:

- Weeks 1-3 (9/2-22): remain only at ~50% of climo overall. These haven’t changed much for days other than a gradual decline.

- Week 4 (9/23-29/new week “on the block”): the first forecast for that week is for 120% of climo and it follows the prior week’s modest 70%. So, it’s seeing some kind of sudden change. If it were a reversion to climo, it would be only at 100%, not 120%. Also, this is the first time there has been any week at 120%+ since the 8/16 run. Will be interesting to follow.

That means gabby should pack it up

I know SSTs are still plenty warm obviously as we approach peak season, but sea temps have fallen across all of the western Atlantic and Caribbean and most of the gulf. A lot is due to Erin in the Atlantic but a lot is due to the train of fronts making very far south for this time of year. In NC many areas woke up to 50s this morning and 60’s made it down to the gulf coast. With more fronts on the way it begs the question of whether SSTs have already peaked in the western Atlantic and whether if a storm approaches that this will help mitigate high end intensity. It is quite literally a 180 from the start of season

 Not that I want H hits in the SE because I don’t as I’d love a boring shutout! But keep in mind that the lowest August temp since 2001 in RDU, GSO, ATL, and most major stations in TN/NC/SC/GA and some in AL was in early to mid August of 2004. That month had a 2-3 week long stretch of BN temps. The very next month had 3 bad hurricanes hit FL.

Oh I am not saying a devastating storm won’t happen, it’s way too early to make that assumption, I am just stating the SW Atlantic and really now almost the entire western Atlantic has gone from the highest departures above normal to solidly below normal. From a sensible weather perspective with repeated fronts, there doesn’t appear to be anything that would brings those temps back up to where they were a few weeks ago. The gulf is still a bathtub but it is only running slightly AN now and most of the Caribbean is near normal now. If we keep the troughiness going in the east and with decreasing sun angle, it seems unlikely ocean temps in western Atlantic will recover to where they were earlier this season. Plenty warm for hurricanes, yes, but there may be a bit more of a limiting factor now than we had. Erin’s upwelling certainly played a huge role but these fronts and nor Easter’s are not typical of this time of year either. Something to watch during this tropical dead period

Feels like the kind of year for some kind of wonky subtropical landfall
