I think they are being cautious at this point because they don't know what the data correction is going to do to the models.

What I read between the lines in Stewart's discussion is that it is possible that the model consenus will shift further south and west. If this shift is significant, they will have to go with Hurricane Warnings for areas that a few hours ago were thought to be on the left edge of the cone, or outside it, and are now in the middle of it.

I have great respect for the folks at the NHC, and it is times like this that I am very glad I don't work there.
