Wow! Never thought we would see this towards the end of October/ early November! As the tropical system makes it's approach to New England, it should transition into a cold core then weaken. Either way it's going to be very strong. GFS has this storm down to 962mb for it's strongest approach to New England. Still far out but it should be interesting what the models do with this storm. ECMWF also has a similar track to the GFS.
Edit: Model Fantasy Land Predictions:
Long Island:
Winds: ENE 50-70mph G to 100mph
Precip: 1/2' to 2' of rain (That's not inches, that's feet)
Obviously this should change, but it's odd that most of reliable global models have similar tracks and strengths.
