Yes, we are painfully aware of Wilma's effect on Cozumel (I've been there three times since). My post was a tongue-in-cheek reference to the over-pessimistic post-Wilma threads in here.
Wilma's wasn't a simple hurricane passage, though. She stalled over the island and slowly dragged her southern eyewall with its devastating onshore winds up most of the western coastline. This made the damage a lot worse and more widespread than it otherwise would have been. Wilma was very much the "perfect storm" for Cozumel, much as Katrina was for New Orleans. A repetition of that type of hit from Dean is pretty unlikely.
I certainly am not making light of the impending storm, but there will be life after Dean irrespective of what path it takes. My thoughts and prayers are with all of you who are there, and to Don - it's time to get the heck outta Dodge, my man!
