Current storm models place Hurricane Dorian entering South East Florida as a Category 4 Hurricane at 8 am on Monday. At the time of writing, the storm models suggest that, by the time this storm hits Orlando, if it does hit Orlando at all, it will be a Category 1 or less.
Disney has its own water treatment facilities and power grid. All buildings at Disney are built far above building and construction codes and can withstand more than Category 5 storms. In the over 4 decades the resort has been in operation I do not believe they have ever once lost power or water. They have enough food and supplies to feed everyone for weeks upon weeks. Not only that, but they have their own police and fire rescue teams.
At this point, Disney may possibly be the safest place to be in Florida during a major storm. If you are at Disney do not panic. Do exactly as the Cast Members instruct you and you will be safe.
Everyone please be kind to your Disney Cast Members this week, and understand they are working while they are trying to prep their own homes for this storm. Instead of being with their families, they are with you. Please respect that there will be folks who will be working tons of extra hours to assist you. They will be tired and they will be worried about their own homes and families. Give them extra kindness and understanding. Thank them as much as you can.
If you are going to be at Disney, we suggest you keep checking Disney's Weather Information page. Disney is currently operating normally, although Blizzard Beach waterpark will be closed on Sunday. You can view Disney's Hurricane Policy here.
Finally, a reminder that things could change, so if you are going to be traveling to Orlando or any other area affected by Hurricane Dorian, we suggest that you bring extra prescription medication with you, just in case your return home is delayed.
It is also important to notify the hotel if you use a medical device that requires electricity: they will do everything they can to help, but the more information they have, the better they will be able to assist you.
