I've been looping the satellite and I think you may be seeing an illusion of a circulation based on cirrus movement. Look like quite strong southwest shear through the western Caribbean. Actually, the disturbance looks more ominous on still images than in the loop (where the shear is so evident). There's no central point of convection, it's just firing here and there. Since it appears the GFS was incorrect about the decreasing shear, I drop my estimate of development potential to 10-15% again. Can't rule it out, but that shear needs to drop off a lot. Probably just a rain-maker for Florida and maybe the southeast U.S. Not much to push it westward.
