An Opal like scenerio is in play. If you go back and look at Opal's track, she formed ON the center of the Yucatan Peninsula, moved North, then WSW into the North BOC, took a turn toward the North and Northeast.
Conditions will be ripe. Isidore's pressure is still very low. Rapid intensification could occur.
