have led to a lot better understanding of how and why homes “fail”
in storm winds.
A few years back, I visited the sites of both the La Plata, Maryland,
tornado and Hurricane Katrina immediately following those storms,
so I got a first-hand look at why things fall apart. In extreme winds,
homes typically go to rack and ruin because of either wind uplift
or pressure differentials as air enters the home.
