Most of the REALLY intense storms I've seen in the past usually have a much larger eye when they complete an ERC. Thats when the bottom falls out as far as pressure goes. Katrina, Wilma, and other cat5 storms seemed to follow that trend. They were annular in nature I believe. I'm not seeing that kind of eyewall with Dean. It hasn't gotten much bigger during the ERCs. The pressure thing is weird. I would think it would rise a bit before dropping like that. Is it possible this happened in the short time recon wasn't in the storm?
