Changed my mind a bit since my earlier post. Looking at the larger sat image of the Caribbean and Western ATL instead of the floater, it is easy to see now that the ridging has moved a little further SE and the boundary is more well-defined, so that may factor into the movement. I don't think the high in the GOM has moved significantly though. At first I thought it had tucked itself a little into the BOC and then moved a little bit to the east, but now I can't that clearly. Looking at the EastPac sat was helpful in seeing that it is just staying put. Also, I think the inertia of the strong convection to the SSW, which is now getting sheared to the SW (she moved to an area with more shear), was possibly pulling Wilma a bit to the SW in lieu of strong steering currents.
