StrmTrckrMiami,
My suggestion is to be calm and get to work now.
Being ahead of the rush is a victory in itself.
Even if it misses you and you have minimal issues, you're prepared for the next one.
Plan as if you're going to be native camping for a few days, because if power goes out, you will be.
As stated, get a hurricane planner and follow the checklist.

But go now, do not wait. Every hour that passes, the more the rush goes and the more likely stores will run out.
I expect the 5pm advisory will be the starting gun

Good luck and remain calm
