Wish I had something to add, but Jeanne is a pathetic looking storm right now. All of the convection is sheared off to the east of the center, which is just hugging the north coast of Haiti. Neither the shear nor the landmass are helping it get any better organized, and I tend to think that the lower pressure & upgrading of the storm is more likely due to a convective burst than anything. I only give it fair odds of surviving long-term, but if it does then there is good potential for it to strengthen...or it could pull a Bonnie. I really don't know.
