Fay has slowed down to a slow Jog over the past 1-2hrs. I do feel a NE movement will begin again. The Pressure still fell due to it tighting up its center overland, but along with that it had water inflow from the GOM and Atlantic and the glades aren't exactly land. Katrina did the same thing over the glades.
So it made the center tighten up, but as FAY moves NE the actual landmass will catch up and weaken her some. Matters where and how fast she gets off the east coast (if at all) to know how much weakening will take place.
