As you know, when hurricanes undergo CREC's or any form of eye generation causes storms to usually weaken. The dry air intrusion also supports this hypothesis. 6 hours is a relatively short time for an ragged eye to form, the storm to start strengthening again, and the dry air to be replaced. 30 + C waters, and an ideal amount of shear give you a good idea of how strong this storm can get!

Notice the latest retrival from the GOES cloud temp.

Bright banding around the center, suggests some form of eye development is taking place.
