This used to be a short strip mall on the Turnpike near Quail Roost Drive, on a site since razed and planted with palms. Note the toppled precast concrete roof support beams, with embedded rebar. Here, frontal winds of at least 120 knots blew out the east-facing plate-glass windows of the storefronts. The internal pressure forces then pushed the walls outward enough for the roof to fall in. This might have been prevented simply by firmly covering all the front glass with 3/4″ plywood.
