The issue that's holding her up is models are forecasting a backing ridge falling in behind Gustov (stretching out from high pressure centralized in the Great Lakes region. In conjuction with this is a mid-Atlantic high about 70W, 30N that seems to be positioned fairly solidly. The backing ridge will hold up Hanna from moving west, and the mid-atlantic high will dictate her N component of motion.
I also noticed that the 1000-5000 THK [576] isopleth appears to be in play with respect to her motion. While its lattitudinally parallel, she's stagnant, but when it inclines SE-NW she begins to move.
Right now, once the backing ridge weakens, she'll begin to move NW. Presently its lookin' like Miami to Titusville will be spared most of the carnage. It looks like she may take a track just north of the Bahama Island chain.

Darkest streamlines are about 50kts.
Projected wave heights:
Darkest red shades zone >35'.
By 08090512z:
Darkest red zone >28' (<35').
How does Gustav compare with Camille so far? About the same or could it be even worse?
The latest models have Hanna turning and heading our way. I don’t much like that....
