This probably has nothing to do with it. But it was something I noticed, and having been through a few hurricanes now...

Wilma seemed very gusty. There were gusts in all hurricanes, but Wilma seemed... I dunno... gusty. <img src="/images/graemlins/smile.gif" alt="" />

I wonder if that had anything to do with it if true. I mean, sudden and frequent loads from gusts are probably harder on structures than sustained winds, right?
