I just watched TB's News. They are on at 11am. John Winter said, "We need to be CAUTIOUSLY optimistic. Do NOT let your guard down in any way, shape or form. Things can change, and as we've seen with Ivan, anything is possible. Even a couple hundred---or even a 100mile change in track to the right --- will make a huge difference in our weather."
He's concerned about that inverted ^ over the western U.S. pushing Ivan further north and east, and at the slow rate he's moving, it is important to pay attention. At the rate this things moving, we might still be looking at Ivan when we're handing out Halloween candy.
I would also add this as a people-watcher: he is not as comfortable as he was yesterday with Ivan's projected path. You can read it in his body language.
