First of all, I'm 100% certain we have Fabian out there now. I'm not sure what "multiple centers" the NHC was tracking overnight, but visible satellite imagery indicates a TS centered near 14.8N/37W.
For the first time, the GFS is concentrating on the REAL storm out east (TD-10) and not the disturbance to the north. As with the tropical suite, the 06Z GFS has a more westward track through 120hrs - just brushing the islands of the eastern Caribbean. But it REALLY gets interesting after 300 hours as high pressure begins blocking it after a NW turn. Note the southwest movement to Miami, stalling, then north to the Carolinas. It's indicating a pretty big/strong storm, too.
Also, the GFDL, for the first time, does NOT dissipate this storm within 24hrs. It carries it all the way out to 126hrs to near 19N/58W or so.
Now, obviously, the chances of this exact thing happening at 384 hrs is not high, but it does imply a greater threat to the east coast from FL to the Outer Banks of NC down the road.
Oh, and it also says that I will be working this coming weekend since we have customers in the NE Caribbean that may be brushed by it.
