There is some support for two potential systems:
1. A wave that leaves Africa around 10/2. Both GFS and Euro ensembles have moderate support for this to develop while on a NNW-NW recurve path. While most have a TS, some strong members make it a hurricane.
2. A wave that enters Caribbean around 10/9. There have been some sporadic signals in the Caribbean for a few runs, but as others noted above, 18z GEFS is perhaps the most bullish and most organized to date.
18z GEFS:
12z EPS (there's some signal for the Caribbean wave):
18z operational GFS today shows both systems for the first time:
