If you're going to live aboard one plan may be to run. Getting just 50 or 100 miles from a storm is a big deal as far as conditions go. You can run to Stuart and have 3 ways to go, North, South or West if you stay far enough ahead.
Andrew in 92 went through Homestead South of Miami. My boat was in Dusenbury Creek in the mangroves in Key Largo and I lived in Miami Lakes in NW Dade (Miami). Boat and House came through no problems, Andrew went right between, about 25 miles from boat and house.
