Sometimes when I hear that people are thinking they can outfit their homes for a Category 4 or 5 storm, I despair. Do they not watch the Weather Channel and see pictures of the destruction these storms do?
Here in Florida, supposedly if you build to Miami/Dade code, and take precautions like boarding windows, etc. your home can withstand a Cat 4. Now that's never been tested yet, at least that I know of, but that's what they say.
