Re: Possible Development in the Central / SW Caribbean
Insane scenario but it would require literally extremely favorable conditions without any sort of interference from dry air intrusion or shear at lower/mid/upper levels.

Re: Possible Development in the Central / SW Caribbean
0z GFS a bit further south, so it crashes into Central America and doesn't seem to get strong on the recurve... So far (out to 252 hrs).

Re: Possible Development in the Central / SW Caribbean
For the record, here is the 2 AM TWO:

An area of disturbed weather has formed over the eastern Caribbean
Sea. This system is expected to move westward during the next
several days, and environmental conditions appear conducive for
gradual development. A tropical depression could form late this
week when the system reaches the central or southwestern Caribbean
Sea.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...medium...40 percent.

Re: Possible Development in the Central / SW Caribbean
Over night trends shields up for the Conus but could be some flooding issues for Central America hopefully nothing to strong.

The GEFS ensembles on tropical tidbits still look a little more north of operational so I wouldn’t call it a strong trend. I think the best thing to do is to see if/where development occurs before we starting to rule out places.

Re: Possible Development in the Central / SW Caribbean
A trough of low pressure over the eastern Caribbean Sea is
associated with disorganized showers and thunderstorms. This system
is expected to move westward during the next several days, and
environmental conditions appear conducive for gradual development.
A tropical depression could form late this week when the system
reaches the central or southwestern Caribbean Sea.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...medium...50 percent.

Re: Possible Development in the Central / SW Caribbean
Some of the strongest members curve away earlier and seem to be Cuba-bound.

So far the GFS remains the only model showing a compact circulation forming. All the rest have a broad disturbance that fails to tighten up.

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.

One thing to note is that the Caribbean Sea is nearly 1.5c above normal, as long as this AOI remains in the Caribbean it'll have at least 30c ssts to work with. I think due to this there's a bigger risk for models outside the gfs/gefs to downplay the rate of intensification than usual.

Re: Possible Development in the Central / SW Caribbean
On the HAFS-B parent of Pilar you can see a near-cat 5 hurricane forming, which seems to come from the same origin that GFS is developing from.

Edit: you can also see it on the 96L HAFS-B parent where it intensifies to 924 mb/145 kt at +126 hrs.

Re: Possible Development in the Central / SW Caribbean
HAFS-B indicates we might just be 4 days removed from a hurricane and 5 days from a cat 5 with a TD/TS in as little as 3 days. Very curious to see whether models will jump on board of if HAFS/GFS will bust, because the timeline is quite close now.

Re: Possible Development in the Central / SW Caribbean
I wouldn't look at parents for other systems when looking to see what the HAFS is thinking for this system.

Re: Possible Development in the Central / SW Caribbean
There is a circulation starting to form up over the Caribbean that fits what the models have been predicting.
