Most South Florida houses can be strengthened fairly easily. Have a family plan and rehearse it. DO NOT wait until the hurricane is approaching to decide who is going to be responsible for which task to prepare your home. A garage is best, right next to the house is second best. Plan to move your boat early.
People die in every hurricane trying to save their boat.
DO NOT let that happen to you. Decide NOW who will be responsible for your water supply. You DO NOT need bottled water from the supermarket. Have containers on hand to hold tap water. You'll need enough for drinking, bathing, and to flush the toilet.
