A turn toward the north is forecast to occur by late tonight, followed by a north-northeastward motion by Friday afternoon or Friday night.

On the official NHC forecast track, the center of Delta will move over the central Gulf of Mexico today and move inland within the hurricane warning area Friday afternoon or Friday night.
