According to the Nat'l Hurricane Center, 99L has been encountering dry air and some wind shear. Looking at GOES infrared, it looks very disorganized. Nevertheless, if conditions improve along with the very warm water it will be traveling over, it could intensify rapidly. OTOH, it's moving at a decent speed and it will soon be influenced by high pressure currently located over the Carolinas. Also, the islands it will be passing over will interfere somewhat with it's development. Although it could become a major hurricane, I'm thinking the chances for that are pretty slim. I hope I'm right!
