Subtropical declaration is quite fitting for this feature considering my own concerns recently posted in the 99L thread in the Storm Forum. It's interactions with the TUTT have led directly to its evolution in this regard, with additional aspect being a tremendous feed of dry air.

The question now becomes, will it complete phase transition and become purely tropical? Timing landfall will be critical in determing that... If it moves quickly toward the Coast and comes onboard than naturally it will only transition into a non-entity. If moves slower than modeled and remains seaward for long period of time, than it will be sitting over some of the hottest waters (Gulf Stream) in the Atlantic Basin and a transition will likely occur.
