Debby's convection, as has always been the case, is largely weighted to one side (in the case of the past few days, on her northern half). Her convective "balls" have rarely been indicative of where her actual center of circulation is, but rather, just where the preponderance of most inclement weather is occurring at any given time.

As can be seen in the ASCAT pass below from earlier today, Debby has just about shed all of her frontal mesh, and has redeveloped a pretty well defined surface circulation.

The above image shows surface winds easily in the 35-40 knot range, especially considering that ASCAT has a well documented low bias.

Given that there is still arguably some meaningful frontal interaction, however lessened it has become this morning, it may be prudent for NHC to hold back on restarting advisories just yet, but it is probably getting to be a close call.
