It's peak season now and look at the satellite images, basin is being squashed by sinking air. However with fronts coming down quick spinups can happen along these boundaries.
I wouldn't focus on any specific GFS but the general signals. Also, as our friend srainhoutx mentions on the KHOU forum, there is some suggestion that a convectively coupled Kelvin wave along with favorable MJO would enhance what we are seeing in the GFS and Euro ensembles about generally lower surface pressures in the Western Gulf and Carribbean.
We are currently in the strongest supressive kelvin wave of the Atlantic season and will persist for at least another week. Hints are showing another suppressive phase continuing. EPAC is where supression effects are less.
Don't mean to belabor a point but you're referring to a suppresive Kelvin wave which is impacting the Atlantic between Africa and the islands. It is not impacting the area of the western Caribbean and western Gulf. And that is my point ... THAT is the area to watch.
