When I lived in Florida, (Homestead AFB) and we went under Hurricane watch, we filled the Tub, and all containers we had with water. Bottled water was unheard of back in those days. I took my boat off the trailer, chained it between two trees and filled it with water. Not to use, but to hold it down. Then we went to the shelter, (Base Gym). Luckily we just got a side swipe by that one. That was back in the mid 70s. I went back to visit Homestead after Andrew. The entire housing area I lived in was gone. Only the concrete slabs left. All those houses were stapled together, no nails, just staples. Shoddy construction.
My buddy living in Ft Lauderdale, gets his batteries and water stocked up before the season starts. He likes to be prepared. In the center of his house is a room of steel reinforced concrete. A very large bathroom normally. When hurricane hits they all just go into that room and hunker down to wait it out. He feels they are better off there than in the local shelter.
The reason my Sister-in-law is in such a panic, she does not have enough sense to do anything on her own. Her husband always takes care of everything for her. He was away at a golf tournament. We talked to him last night, after he arrived back home. On his way home he stopped at a store and stocked up on batteries and water. Also canned goods they could use if it gets bad. I respect him, he is always calm, cool, and got it together. Why he married such a dingbat I'll never know. She was a school teacher for over 30 years. Poor students.
