Should You Open Or — Close Windows During A Tornado 'link'

Here is the definitive guide on why you should keep your windows closed during a tornado.

For decades, a persistent piece of folk wisdom has suggested that opening windows during a tornado will equalize pressure inside and outside a home, thereby preventing the building from "exploding" due to rapid pressure drops. This report analyzes historical and contemporary data from meteorological science and structural engineering. The conclusion is unequivocal: The practice is not only ineffective but dangerously counterproductive. Opening windows wastes critical survival time, weakens the structural integrity of the building envelope, and increases the risk of wind and debris ingress. The only safe course of action is to close all windows and doors immediately and seek shelter in a pre-designated safe room, basement, or interior, windowless ground-floor space.

When a tornado warning is issued, adrenaline spikes and time is of the essence. In the rush to secure your home and family, you may recall a common piece of folklore: "Open the windows to equalize the pressure so the house doesn't explode." should you open or close windows during a tornado

Some people believe that opening windows on the side of the house facing the tornado will help equalize the air pressure inside and outside the home, reducing the likelihood of the roof being blown off. However, this theory has been largely debunked. Here is the definitive guide on why you

While it is true that tornadoes have incredibly low pressure centers, the idea that a house will explode due to pressure differential is largely a myth.

The "open window" myth originated in the mid-20th century, based on a misunderstanding of the Bernoulli principle and atmospheric pressure dynamics. The theory posits that a tornado’s core pressure is significantly lower than the surrounding environment; if a house is sealed, the higher internal pressure will cause the roof to lift off and the walls to blow outward. This report will dissect this theory by examining three key areas: The conclusion is unequivocal: The practice is not

If a tornado is approaching, leave the windows alone. The risk of structural damage comes from the sheer power of the wind and flying debris, not air pressure.

While this advice is passed down with good intentions, meteorologists and structural engineers agree that it is not only incorrect but potentially dangerous.
