The GFS now takes Emily further to the east. Of far more interest is that the movement in the past 6 hours has been just about due west at 12 knots. Water vapor indicates about 9 degrees of separation between the base of the trough and the center of the tropical storm - and that is still quite a bit. The trough may dig a little further south, but not much. The NHC forecast places the center of Emily onshore the Dominican Republic in about 19 hours - which is going to be a bit of a stretch if the western motion continues tonight. ED
0z GFS is slightly west and slower of the 18Z or even though 12Z GFS.
Be interesting how far west this gets. I still say the main factor will be where it makes landfall in Hispaniola.. if it can get past 71.5W on the Haiti side.. then it will be further west in days 3-4 and might make 80W. Short term movement over the next 24hrs will be key.
