The answer is no. Opening windows during a tornado will do nothing for you but waste precious time that you should be using to see... Tornado Alley Armor Tornado Myths - Missouri StormAware “Opening the windows in your house before a tornado will reduce damage by balancing the pressure inside and outside the structure. Storm Aware (.gov) Show all Wind, Not Pressure, Is the Enemy: Houses don't explode because of air pressure differences. Destruction is caused by violent, horizontal winds and flying debris. The "Wind Tunnel" Effect: Opening a window allows intense wind to rush into your home, creating internal pressure that can push up on your roof or outward on your walls. This can lead to structural failure much faster than if the house remained sealed. Flying Debris and Shrapnel: Keeping windows closed provides an extra barrier of protection. Opening them invites high-velocity debris, glass shards, rain, and hail directly into your living space. Every Second Counts: The time you spend running to unlatch windows is time you are NOT spending in your safe room. Tornadoes move quickly, and those precious seconds can be life-saving. The Origins of the Myth The "exploding house" theory was actually standard wisdom in many mid-20th-century emergency manuals. It wasn't until thorough research was conducted by the
The pressure drop inside a tornado is significant but relatively gradual—on the order of tens of seconds. The human body doesn’t even notice it (ears rarely pop). Modern homes are leaky enough (through vents, doors, soffits, and cracks) that pressure equalizes naturally without needing to open a window. do you open your windows during a tornado
The Myth of Open Windows: Debunking a Tornado Safety Fallacy The answer is no
No, you should never open your windows during a tornado. For decades, a common myth suggested that opening windows helps "equalize pressure" to prevent a house from exploding. Science has proven this false. In reality, opening windows wastes life-saving time and actually makes your home more dangerous by allowing high-speed winds and debris to enter directly. Why You Should Keep Your Windows Closed Storm Aware (
The idea that opening windows mitigates tornado damage is a meteorological urban legend. Physics dictates that structural failure is caused by wind force and debris impact, not barometric pressure explosion. Opening windows can actually exacerbate wind damage by directing air flow into the structure, creating uplift. Therefore, residents should ignore this myth and prioritize immediate shelter in a reinforced, interior space. Keeping windows closed saves time and saves lives.
Use pillows, blankets, or even a bike helmet to protect yourself from falling debris.
