The models all show a general NW motion till Weds, then a run of nearly 24 hours DUE west, moving Gus thru the gap between Cuba and Jamacia. The models (and NHC) are very good within a 3 day window especially when all of them agree. Once again the water vapor loop shows a good push coming from the north of Gus's current position, so that will limits its northern movement. Basically it will hit a wall at about 20 N, then have no choice but to go more west. There is a weakness to the east of FL (in the Bahamas) that provides a window for northern motion but that window does not open till Gus gets to atleast 80 W which will take till Thursday at his current speed.
