At Stennis Space Center NASA uses the NHC forecasts for action...

my initial thoughs on Dennis is that I just don't think we'll have the same type climatological conditions that saw Charlie take that hard right to the NE and plow through Punta Gorda... my gut feeling, even if the ridge now protecting Fl were to weaken, the system will take a more classical route similar to what Georges, Frederick and Ivan took.... the ridge would really have to weaken significantly and you'd have to have upper air dynamics pushing the system off to the NE... of course I could be totally wrong and probably will be but right now everything looks to be setting up for a central or east central Gulf Coast event... as Jason Kelly says, look for the trends in the models, not just one or two runs... you need only to remember what the models did with Ivan... they basically stunk up the place and were way off 5-7 days out and I think only the Canadian was the western outlier and had the system moving towards the Gulf Coast...... anywho what the heck do I know.... my speciality if boarding up windows...
