I think too much emphasis is put on the gulf stream effect on average storms. The gulf stream has always been there and the only way it affects storm development is if the storm has already become volatile and just needs the extra dynamics to go to the next category level. The other thing that I have noticed is that sometimes the storms get caught over the gulf stream due to conflicting air masses but if they do they usually ride it up to the northeast coast and come in around North Carolina or further north. Although computer graphics and data are very entertaining, they are after all just replicated information that has happened in the past. The liklihood that something entirely different than we have seen in our life time has a 50 -50 chance of occurring each hurricane season.
