At this point, Ivan is at an intersection between influences from the ridge and trofs to the north. Generally, tropical cyclones are steered by the ridges south of 20 N, then as they drift north of 20 N, they encounter more trofs and sheer causing them to accelerate northward and eventually transition to extra-tropical systems. Ivan is still under more of an easterly flow regime right now, but it looks like that will be changing over the next 2 days. Continued westward movement to the northern tip of the Yucatan isn't out of the question however. Surface pressures still remain relatively high at Havana and Key West compared to Cozumel and Cancun.
