Looking at the latest GFS model (about 11 hours old...should be a new one soon, I think), it shows TD9 remaining weak throughout the 6 days, and has it following Harvey north almost exactly on the same old track.

However, a more intersting point is what it does to that wave behind 09. It is pulling it into a rather strong vortex within 3-4 days.

Also, it shows that low off the FL/AL coast strengthing its vorticy and another swirl coming up in the gulf and heading toward central America (though not strong).
