I dunno about a Cat 5, solid Cat 4 or Cat 3 sounds more likely. If she can stop replacing her eyewall every 12 hours then possibly because there is very little shear and lots of warm water, and high heat content near the Northern Bahamas and off the coast of Fl. I dunno about rapid deepening though, usually storms that blow up before landfall are small, compact hurricanes ie. Charley, Andrew. But ya never know. Just have to keep watching. Thoughts anyone???
