You should invest in Hurricane shutters when it's all done and over, back home in Florida almost everyone has either shutters or impact windows
When Irma was going to full impact hit Ft Lauderdale it was supposed to be a cat 5 but it ended up wobbling to the left and it missed us thank god. We still got a cat 2, some people lost power, a lot of boil water warnings. Also, if you're going to evacuate now is probably too late as everyone and their mother is doing that.
Good luck, and be prepared to live without AC for a while.
