All major meteorological and emergency management organizations explicitly advise against opening windows. The National Weather Service (NWS), the Federal Emergency Management Agency (FEMA), and the American Red Cross agree that residents should immediately seek shelter in an interior room on the lowest floor, away from windows and doors.

Stay in your safe zone until the official warning has expired. Summary of the Myth vs. Reality The Myth The Reality Opening windows equalizes pressure. do you open your windows during a tornado

Atmospheric pressure differences between the inside of a home and the center of a tornado are indeed significant, but they do not happen instantaneously. A tornado moves, meaning the pressure drop is transient. Even if a house were perfectly sealed (which most houses are not, due to vents, chimneys, and general air leakage), the structural integrity of wood, brick, and drywall is capable of withstanding the pressure differential. The explosion effect often seen in tornado aftermaths is caused by wind entering the structure, not by pressure vacuum alone. Summary of the Myth vs

It sounds logical. A tornado is a violently rotating column of air with extremely low pressure at its center. The idea is that if this low pressure passes directly over your home, the higher pressure inside will push the walls outward, causing the house to “explode.” Opening a window, the theory goes, allows the pressures to balance, saving the structure.
