A protective shelter includes an enclosure having at least a floor, at least one sidewall coupled to the floor, a door, and a roof coupled to the at least one sidewall. The roof includes an aperture located proximate the shelter's point of minimum static air pressure during a high-velocity wind event. The protective shelter includes one or more members that elevate the floor above a substrate, a substantially enclosed sub-floor region bounded by the protective shelter and the substrate, and an air duct providing airflow communication between the substantially enclosed sub-floor region and an exterior region of the enclosure via the aperture.
