I remember Cancun before and after Gilbert. My folks used to have a time share down there. One image isl still in my dad's head from their trip in 1989. "A new hotel on the beach was leaning at about a 15 degree angle," he wrote in an email. "Eventually it had to be torn down. I can imagine what is happening now that Wilma won't go away. I hope the fish still have heads."
As for Florida, Masters says that Wilma could stick pack category 3 hurricane winds when it makes landfall. Or it could be merely another tropical storm. It depends on how much time Wilma spends hanging out over the water.
Given all these factors, I don't see any reason to change the range of probabilities I gave yesterday for Florida. I'd give Wilma a 10% chance of arriving on the Florida west coast as a Category 3 or higher storm, 20% as a Category 2, 40% as a Category 1, and 30% as a tropical storm. On Florida's east coast, knock these value down by half a Category (10 - 15 mph).
