In a couple days we should know if Issac is going to make a reappearance in the Gulf. Right now they are giving him a 30% chance of reforming. Currently he has very little convection over the low level circulation center. There is an area of moderate convection about 150 miles to the South West of the center that is just starting to get drawn in. As of sunset the low level center was easily visible on sat images, and fairly well defined. Most models do have him back up to tropical storm strength around Sunday afternoon.
