I wouldn’t jump the gun on 95L just yet. I remember Bonnie ‘22 had some very aggressive Euro runs for a while showing a Caribbean Cruiser major, but the precursor wave was too far south and didn’t develop until it was finally past South America. I’d say there’s a non-zero chance that scenario is on the table for 95L too.

SHIPS, just why. A major is out of the question and in reality it’ll be falling apart by the end there after peaking at 60-70 kt.

Keep in mind SHIPS is a statistical model & does not directly take into account time for an invest to organize into a TC. The model treats this as it would your average tropical depression.

Did Elsa 2021 and Bonnie 2022 have such intense ensemble signals from the ECMWF? As in, numerous members reaching major strengths like that? Those recent 12z runs really got me wondering that.

18Z GFS is running and is the strongest GFS run since 0Z last night.

Happy Hour GFS, something is going to give as the euro and gfs were seeing things differently in the carib.

Bonnie, yes. The Euro was really trigger happy with that, only for it to bust. I forget what its forecasts for Elsa were like.

Speaking of Elsa, I’m expecting a very similar storm at the most: a Cat 1 passing through the Lesser Antilles before falling apart in the Caribbean.

GFS has a potent hurricane in 5 days with TC formation already within the 2 - 3 day timeframe.

[IcyTundra]

18Z GFS weakens 95L in the Caribbean which would make sense this time of year. It has a 2nd system behind 95L that the Euro doesn't have though. Not sure how a 2nd system like that would effect 95L.

Despite the E Car weakening on the 18z GFS, this run screams potential GOM trouble with improving conditions near the Yucutan, which ironically is where the Euro shows it to be.

18Z GFS has ridging along northern gulf coast, brings storm in across the Yucatan south of Cancun.
Significant shear from the south depicted this run all the way across the Caribbean.

Less shear would mean bigger storm probably more pole-ward track earlier.

If 95L is strong enough entering the E Car to survive the "graveyard" it could cause some trouble. The Euro also takes 95L further south in the Caribbean which there might be more favorable conditions in the far south Caribbean.

I believe the difference in intensity has more to do with orientation of upper level winds. The GFS has upper level winds out of the southwest, directly perpendicular to storm motion, undercutting the outflow layer and inducing shear. OTOH, the Euro maintains upper flow out of the southeast, generally aligned with the storm's motion (potentially even providing ventilation). It looks like the root cause might be difference in orientation of the TUTT far west of the system.

12z eps, very interesting (unlike the Nwpac)

[Hurricaneman]

The GFS is trending towards the Euro, might have something more significant in the western Caribbean than we may have otherwise have this time of year, but the Yucatán may have anything from a weak low to major hurricane so stay tuned and while I think this will be a 50mph TS at landfall in the western Caribbean this could be just a wave if TUTT shear stays but a stronger system is also possible but we won’t know until early next week
