Don't expect quick intensification over the next 18-24 hrs or so, the Euro is still persistent in windshear getting low enough for quick intensification for at least 36 hrs before making landfall in a moist environment and over 30-31F SSTs.

Just like Jon Snow..."I know nothing" except what I know, and most of what I know is gathered by the fine people of the NHC

By Franklin tracking further west than forecasted earlier is definitely preventing the Caribbean ridge from building a narrow nose over the Bahamas that far north.

18Z GFS with the casual 2MB/hr pressure drops continuing for 24 hours straight. :eek:

Just my opinion. GFS was W global outlier during Ian and kept that NHC track offshore into Big Bend. It’s happening again, the GFS is an east bias model, something will give and maybe it will be right this time. I’m betting it won’t.

Does anybody believe the brief NNW movement by the GFS after Western Cuba before going back N to NNE? If it were not for that, it would match the Euro track. Could see more east shifts by the GFS in subsequent runs.
