It will all depend on timing. If the upper level trough backs up before its influence on Dean is felt, it will remain on a southerly track. If not, it will be pulled to the WNW or NW. we have come a long way since I worked at NHC, but forecasts beyond 72 hours are still dubious. Oceanic heat potential in the western gulf is as high now as it was for Rita and Katrina. A cat 4 or 5 landfall is possible several days from now. It appears that little in the way of features will weaken Dean significantly, except an encounter with land like the Yucatan. Eyewalls like to replace themselves every few days. This leads to temporary weakening. Some have been lucky enough to have this happen near landfall resulting in a system 1 or 2 categories weaker. In any event, I wish you guys the best. Take to heart the lessens of Sub Umbra and hope we never have to live them out.
