eastern carrib even in peak season is rare.

this has towers developing and starting wrap to the west ans SW side now.
LLC is quickly trying to develop.

This will develop way before reaching the western Caribbean.


HWRF parent has been showing for a few days now.. at the tale end of the ZETA runs.

I don’t like how this is being frequently compared to Mitch, Wilma, and Paloma this early, combined with its rapid organization.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

Reminds me of Wilma.


Thought that was gonna happen with Delta but then that unexpected mid-level shear showed up. Once again, all we can say is the potential is there...


I haven't seen an anticyclone depicted like this all season long.
One huge updraft across the entire W Carib
This is not an ARWB with a displaced anticyclone that creates a mid-level or upper-level jet over the CoC.

If this develops early, I see no reason why this can't become something big with that environment. Would a stronger Eta (i.e. a major hurricane) be more or less likely to get buried into Central America?

I would certainly think so in terms of early development hence euro ensembles. Gfs slowly coming around to this idea

Interesting...I thought the stronger runs would be those that kept it offshore and awaiting the trough and the weaker runs send it inland faster, but I wasn't sure if that was the case.

This is scary potential, no one needs a cat 4 or 5 in central America, Cuba, Yucatan or Florida\Bahamas so this will have to be watched as the potential is higher than any hurricane this year based on conditions modeled

The only analog I can think of is the 1932 Santa Cruz del Sur hurricane...

It seems like the only inhibitor we can foresee right now will be the potential for land interaction with CA, but even that is starting to look less likely :roll:

It needs to slow down, looks like it's pacing to the point where it will have some trouble trying to consolidate, unless the gif is sped up.

Pretty much every 18z Global model run has a storm moving into CA in the 96–120 hr timeframe regardless of strength, some with weak TS and others with hurricane.

Yeah it's some user who uses the "eek" emoji a lot when he posts noodle runs. Pretty smart guy. :wink:

Ah... :ggreen: It’s pretty clear a low level circulation is trying to develop but to me it might be still in the mid levels. Only a matter of time

I think it’s sped up or an illusion. Normal radar shows it’s not moving slow but not too fast to inhibit development clearly :lol:

I'd bump the probabilities up to 60/80 at the next update personally. Clearly developing but need persistence. Probably should consider setting up Recon for Saturday.
