Posted two days ago that it is going west.
If it continues the course of the last few frames and does not turn west, it will cross the Keys and into the Gulf, hammering the Keys and raking south Florida. Other strong hurricanes have tended to take a parabolic path like the one Irma has generally followed until something else big enough changes it. With the bigger storms, it takes a bigger system. What I really wonder is if Jose has been fully taken into account.
After tracking WNW over the Cuban Keys, Irma just went due West and that took her inside the Cuban Keys and she will hit Cuban mainland right about now. If she keeps due West will go out over water again as Cuban coastline recedes a little in a Bay. Then back on land again.
How far west could it go?
