I suggest you use this website:
http://skeetobiteweather.com/ the first page that pops up will have any named storms that are in or expected to be near the Atlantic side of the US. It will show not only the official paths of the storms that are being used by local meteorologist but will also show you the all the main computer models. If you prefer a more difficult to understand source you can also use
http://www.tropicalstormrisk.com/ it will also give you the highlights along with forecast for all of August that is pretty much what most experts would use as a source... When I was working in a gas trading company that was concerned with hurricanes in the Gulf region those were two of the most popular sources that traders would use. Frankly I suggest you just stick with the skeetobiteweather but I included the other just so you could see that they basically show you the same information only skeetobite is more to the point and leaves out a lot of the really long term stuff that is more guess than anything else.
