Watching vis sat loops can be deceiving, but if you use the NASA GOES sat pix loops, it certainly appears that ExTD2 hints of a rotation in the midlevels, with outflow being propelled clockwise. Best estimate of the possible center of the rotation is SE of the western tip of Cuba, and the system that is rotating, if it is rotation, is moving off to the NW, heading toward the GOM between Cuba and the Yucatan.. This system has been written off so manys times its probably a CFHC record. I don't think you can really ever write them off until the are well inland.... My opinion is that if it can at keep what it currently has till it gets to the GOM, it still has a shot at development....
