Folks this looks like we might have an Annular Hurricane here as was Isabel (image attached) at some point as was Katrina
http://en.wikipedia.org/wiki/Annular_hurricane
if you have questions about what one is...but this is looking like a classic one...might even already be Cat5...wish we had a pressure reading...its 'L O W' I am sure.

"An annular hurricane is a tropical cyclone in the Atlantic or Eastern Pacific Oceans that features a large, symmetric eye surrounded by a thick ring of intense convection. This type of storm is not prone to the fluctuations in intensity associated with eyewall replacement cycles, unlike typical intense tropical cyclones. Annular hurricanes also tend to persist, even when encountering environmental conditions which easily dissipate most other hurricanes. Forecasters have difficulty predicting the behavior of annular hurricanes; they are a recently recognized phenomenon, and as such, little is known about their tendencies. Because of this, they can be more dangerous than typical hurricanes."
