FORBES: Better Than Fab: Your Very Own Style Graph

Well, hurricane strikes are actually a really poor measure of hurricane activity, since whether major hurricanes hit land or stay out at sea or hit some other country is pretty random (the only metric that is worse is hurricane damage numbers, which are biased over time and geography with large variations in coastal development value).
