8AM Yesterday:

11AM This Morning:

As you can see from the top two pictures the models seem to be coming into agreement. The 6z GFS and NAM did shift farther this morning. I think Danny will be more west than were Bill was and make it to a Cat. 1 hurricane when it's off the coast of the Outer Banks. It should stay off the coast but closer than Bill. I will have a full update tonight.
