A tropical wave starting to interact with a mostly stationary front is producing vigorous showers and thunderstorms in the central to western Caribbean, and this feature has increasing odds of developing by the end of the week.
This disturbance has not yet been Invest tagged, but will likely soon be. Interests in the western and northwestern Caribbean may want to begin paying close attention, as even if tropical cyclone development does not occur before the end of the week, very heavy and flooding rains are almost a certainty, either way. Additional details and images to come.
At 7PM CDT Oct 2, TD25 has been named: Gamma

As of 11AM, 10/2, it is officially TD 25. It does not appear to be a threat to at the moment. Forecast to become TS Gamma by tomorrow.
Since we are now into October/November, this is the prime region for storm development.

GFS 12Z has a strong hurricane spinning up in the Caribbean, crossing Cuba, then impacting Florida peninsula in 2 weeks: https://www.tropicaltidbits.com/analysis/models/gfs/2020101212/gfs_mslp_pcpn_watl_60.png
Each of the last 3 model runs has been further west and stronger. 12Z was a bit slower bringing the system out of the Caribbean, consequently more time over warm/deep seawater allows pressure to bottom out around 941mb prior to Cuban landfall. While 2 weeks out is a hard sale for any model to pin on, the 12Z and the relative run to run consistency
