Stay safe everyone!
Definitely board up all windows, even the new ones.
In addition to what MK listed....Be sure to refill any meds etc that you all may need as well.
Stock up on batteries, water, juices, and non-perishable foods.
If you have and plan to use a generator, please please DO NOT run it inside your house or near areas that can get inside your home (carbon monoxide fumes).
ETA: Another item we keep stocked in hurricane season is a portable outdoor cooker with several re-fill-able tanks filled. Can't for the life of me think what it's called atm. Butane, propane. But you get the idea. Something to cook on if needed in power outage areas.
