Excellent observation...center has reformed to just barely offshore Appalachiacola, FL...visible imagery has the tiniest of centers there.

I believe the center is now moving S or SSW, unless it is a wobble or being elongated. We'll have to wait and see for the next fix, I guess. Below is a link to the radar.
Please correct if I see this wrong.

I have a question. it's one of those murky areas ...some years there is much discussion and other years not though mostly related to west bound tropical waves.
Why is this not considered a decoupled system... she definitely seems to have two centers... upper or mid level and another lower level. I've seen waves and depressions where the waxed poetic on this... but this storm that hovers just off of the coast seems to fit that basic... example.
Watching a long loop of the visible floater you can see one part moving consistently and the other anchored back below barely moving. Not just blow ups but what seems to be the storm moving. I know... "seems" isn't fact.

Trying to understand this difficult to understand storm.

I will take a crack at answering your questions - 1) West moving tropical waves have their weather "behind" the wave and not in front of them; whereas with shortwaves and troughs generally have their weather in front relative to movement. 2) Debby is not decoupled for a couple of reasons; one she's not vertically deep but is depicted on upper air analysis with a circulation to at least 500 millibars or 18,000 feet MSL as she currently is this evening; two, looking at the water vapor imagery this evening, Debby isn't much more vertical than depicted at 500 millibars; there is no cyclonic or anticyclonic rotation evident. What is evident is the deepening trough along the Eastern Seaboard as heights continue to fall along the coast and winds aloft at 300 millibars or 30,000 feet MSL depict winds coming around at Charleston, SC from ESE to NW. The 26/03Z discussion has indicated that the low level center is subject to re-define itself dependent upon where convection fires so expect more vortices and a jumping of coordinates.

Well TD Debby is now moving more to southeast is located right over Cedar key and this is reflected by 997mb pressure there. After coming just barely ashore in Dixie county.
