Re: Possible SW Caribbean Development
Per the climo/history of TCs on record with genesis in the 2nd half of Oct that went on to hit FL since 1851, there have been 7 that formed in the Gulf vs 5 in the W Car. So, don't be surprised if this ends up first becoming a TD in the Gulf as opposed to W Car and that it then comes back E to NE into the stretch from the Panhandle to Tampa area. These 7 that did just that:
- Love of 1950 (Big Bend)
- #6 of 1904 (Panhandle')
- #9 of 1892 (Tampa)
- #16 of 1887 (Tampa)
- #7 of 1877 (Big Bend)
- #5 of 1872 (Tampa)
- #8 of 1859 (Tampa)(only H landfall of these 7 as other 6 were TS at landfall)

926 mbar from GFS-P!
Zeta goes further west due to the lack of a weakness in the ridge from Epsilon, but eventually it starts to turn to the N/NE.

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.

12z GFS-P is pretty much nearly identical to the 06z run just south of Cuba instead of north. Goes east and then back west through 270hrs.

Re: Possible SW Caribbean Development
GFS 2.0 goes East, just south of Cuba, then building ridge shoves it back West with some resistance.

Re: Possible SW Caribbean Development
Noticable difference between the 12z and 06z is that the ridge almost looks like an Omega block.

GFS 2.0 doesn't know what to do - as it should.

I think several of the northern members are the subtropical system, which recurves close to Bermuda’s longitude around that time on several runs.

921 mbar on the 12z GFS-P run. Today’s Happy Hour run is going to be absolutely insane...
