The fly in the ointment may be that trough. If my eyes don't deceive me the trough has in fact lifted NE but is leaving a deepening ULL in it wake and that is squarely where Hanna was two days ago. This is uncoupling the LLC from all the convection. Can Hanna survive that? Hanna has had that type of problem all along with an ULL shearing convection last week , then shear from Gustav, and now this. This new feature is more robust than the one she encountered while developing last week and is virtually on top of her. I would not be surprised to see Hanna continue to fade.
