We don't really keep an eye out for hurricanes but in all our 43 trips, mostly early fall, we have incurred 2 hurricanes, really nipped WDW. WDW is all about safety and if I had to ride out a hurricane it would be at WDW. Structures are built for the winds and rains and CM's are prepared.
Our big problem came when it was time to go home and the hurricane did damage to the rails, we come and go by Amtrak. We had to extend our stay 3 nights before Amtrak was up and running. Disney property is safe but you must watch out on how you're going to get out, especially the route home, if damage was incurred along your route it may not impact you at WDW but somewhere along your route home. By car, train or plane you must be vigilant.
