The upper-level high pressure ridge has weakened over Florida and the eastern Gulf, while a strong upper-level disturbance is diving into eastern Texas. This will help to maintain a weakness in the upper-level wind flow over the central Gulf, and Dennis will turn northward ahead of this weakness. If the Atlantic high pressure ridge fails to build farther west, Dennis could track close to the west coast of Florida Saturday. If the upper-level high pressure ridge builds stronger to the west, then Dennis will be diverted more toward Louisiana. We should know soon what Dennis will do.
