Looked at the latest vapor loop a lot, here's my attempt to diagram some of the features.

A) Dry air, was diving southward toward the convection, but isn't wrapping or flowing eastward. Seems now to be moving as a mass westward, so the dry slot could reach the eastern islands and Abacos before the convection.
B) A cyclonic circulation, but I can't say at what level; swirl was prounced in vapor loop but without much convection.
C) Where I looked for wrapping convection, didn't see it yet. (D) is the direction of what looks like high outflow from this area.
Like to hear what the more experienced amateurs and pros see in the loop reagrding the development scenarios.
This is the loop I was using (zoomed in):
