If a Tornado Warning is issued, follow this door protocol:
This feature explores the science behind wind dynamics, the origins of the dangerous "open door" myth, and the specific structural benefits of keeping doors shut during a wind event.
Tornadoes cause extreme pressure drops. When a tornado breaches an exterior wall or window, the sudden pressure inside a single room can cause that room’s roof or walls to blow outward. Closed interior doors limit the volume of air that can rush in, reducing the force exerted on the structure.
In the event of a tornado warning:
Tornado winds turn household items into missiles. An open door acts as an open invitation for debris to travel through the home. A closed door acts as a shield. While an interior hollow-core door may not stop a 2x4, it will stop flying glass, small debris, and loose items that could cause injury to occupants sheltering in an interior room.
The persistence of the "open doors" advice is a case study in scientific lag.
