CJan, that would be a good tacked post here.
As for storm proofing a House, There are a few things I didn't do, but can at least retrofit them later. To start after talking to a few local contractors....I was not happy with any of them. It was we build you house our way. I went with a manufactured house. It was built in a factory, kiln dried wood, no weather exposure, and more strength.
The house is built is boxes and they are stacked on site. Each box is one structural unit, they do not rely on another unit for their strength. Outer walls are 2x6 on 16 centers. The marriage wall (where the boxes join) is two 2x4 walls bolted together. The floor is 2x10 and ceilings are 2x8. I kept penetrations in the marriage wall to a minimum to enhance their strength. Since they are trucked to the site they have to be able to handle road vibration and bumps. I had far less sheet-rock cracks than houses I had toured prior to buying, I feel that since they had all 4 walls per box the strengthen it.
The house is also built to Rhode Island code which is stricter than NJ especially with snow loads. As NJ didn;t require me to bolt the marriage wall at the top, but I did that anyway. Also I went back and did many fasteners at closer intervals than required. One being the straps that fasten the boxes to the sill plate. one every 2' instead of 4'.
As designed at the manufacturer the house can handle a category 4 storm.
