I hesitate to call it exploding... it's intensifying, but... what i think you're seeing is a system that was poised to strengthen, being held back by the interaction with the bahamas. It's free of that influence, and now it's simply gotten to the strength it probably woud have been without land interaction. (In otherwords, the disruption of the inner core has lessened, so the system is able to take better advantage of the positive environment.

Now, if they find it a cat 3 by 11pm, I might be more willing to say it's exploding

I know Katrina just happened, but can we avoid Katrina-like Comparisons for now? Just like Camille, I think Katrina should be the flhurricane equivalent of invoking "Godwin's Law"
