As noted by Kevin on the Main page, the Navy has decided to classify this system as a TD (this means that NHC will probably do so at 5pm). At 18Z I had the center at 29.0N 88.6W. Movement was toward the northwest or north northwest, but rather slowly. Best outflow is in the northeast quad. Buoy 42040, which is near the center at 29.2N 88.2W, reporting East wind at 21kts gusting to 25kts, pressure 29.94, sea temp 84.7F, wave height 6 feet. Organization is quite good and getting better. TS strength is still possible - a slow mover in the north Gulf can still wrap up - even those that are close to shore. I'd anticipate more of an eventual turn to the north - perhaps toward Mobile Bay. Here is a link to the buoy:
NDBC Station 42040

5:40pm Update: Mid-level circulation center near 29.3N 88.2W seems to be stronger than the LLCC. Greatest pressure falls are taking place in the Pensacola area - no doubt associated with the closer proximity of the mid-level center.
Cheers,
