Why You Shouldn't Open Your Windows During A Tornado

Tornadoes are one of nature's most destructive forces, capable of causing significant damage in a matter of seconds.

As a result, it is crucial to understand the best safety practices when faced with a tornado threat. One common misconception surrounding tornado safety is the advice to open your windows during a tornado.

The Old Theory and its Evolution

In the past, it was believed that opening windows during a tornado could prevent your house from exploding. This theory was based on the idea that the drop in air pressure caused by a tornado hitting a building would create a higher pressure inside, leading to an explosion. However, this theory has since been debunked by scientific research and real-life observations.

Lessons Learned from Wichita Falls Tornado

One significant turning point in tornado safety occurred in 1979 when a massive tornado struck Wichita Falls, Texas. The damage caused by this tornado provided valuable insights into the behavior of tornadoes and their impact on structures. Researchers studying the aftermath of the Wichita Falls tornado made several key observations that challenged the old theory of opening windows during a tornado.

The Role of Reinforced Structures

One important lesson learned from the Wichita Falls tornado was the importance of staying in a reinforced structure during a tornado. Unlike automobiles, which can become steel death traps in a tornado, reinforced structures offer a higher level of protection. Homes with storm doors and shutters were found to be less damaged compared to those without these features.

The Science Behind Tornado Damage

To understand why opening windows during a tornado can be dangerous, we need to delve into the science behind tornado damage. Tornadoes generate extremely powerful winds that can exceed 200 miles per hour. These winds can exert tremendous pressure on structures, leading to structural failure.

Wind Pressure and Roof Lift

When a tornado approaches a building, wind blowing into open or broken windows can push up on the roof. At the same time, wind blowing over the roof can create a lifting force, similar to the wings of an airplane. If the roof is not properly secured, this lifting force can cause the walls to fall outward, creating the illusion of an explosion.

Debris and Projectile Hazards

Another factor to consider when opening windows during a tornado is the risk of debris and projectiles. Tornadoes can pick up and hurl objects at high speeds, turning them into deadly projectiles. Opening windows increases the likelihood of debris entering your home, posing a significant threat to your safety.

The Priority: Seek Shelter in Interior Rooms

Given the risks associated with opening windows during a tornado, it is essential to prioritize seeking shelter in interior rooms. When a tornado warning is issued, the most important safety rule is to take shelter in a sturdy building, away from windows.

Basement as the Safest Option

If you have a basement, it is the safest place to seek shelter during a tornado. Basements provide a natural barrier against the powerful winds and flying debris associated with tornadoes. If you don't have a basement, find an interior room on the lowest level of your home, such as a bathroom or a closet, to take cover.

Reinforced Structures and Safe Rooms

For those who live in areas prone to tornadoes, reinforcing your home or investing in a safe room can provide added protection. Safe rooms are specially designed to withstand the strong forces exerted by tornadoes and offer a secure space for individuals to seek shelter.

The Reality of Window Damage

While it's important to prioritize seeking shelter in interior rooms, it's crucial to acknowledge that tornadoes can still cause window damage. The strong winds and flying debris associated with tornadoes can break windows, leaving your home vulnerable to the elements. However, closing windows during a tornado is not the priority. Instead, focus on finding a safe place away from windows to protect yourself from the storm's immediate dangers.

Dealing with Broken Windows

If a tornado damages your windows, it's essential to take precautions to prevent injury from shattered glass. Cover broken windows with mattresses, thick blankets, or even sturdy furniture to minimize the risk of glass fragments flying into your shelter area.

Secondary Protection Measures

To further protect your home from window damage during a tornado, you can install impact-resistant windows or storm shutters. These protective measures can help reinforce your windows and reduce the risk of shattering during severe weather events.

Tornado Preparedness and Safety Tips

In addition to understanding the dangers of opening windows during a tornado, it's crucial to be prepared and follow safety guidelines to ensure your well-being during severe weather events.

Stay Informed and Have a Plan

Stay updated with the latest weather forecasts and warnings by monitoring local news, radio, or weather apps. Develop a tornado safety plan for your household and ensure everyone knows what to do in the event of a tornado warning.

Prepare an Emergency Kit

As part of your tornado preparedness, assemble an emergency kit that includes essential supplies such as non-perishable food, water, flashlights, batteries, a first aid kit, and any necessary medications. Keep your emergency kit easily accessible in case you need to seek shelter quickly.

Practice Tornado Drills

Regularly practice tornado drills with your household to familiarize everyone with the necessary actions to take during a tornado warning. Designate a safe meeting place within your home where everyone can gather after seeking shelter.

Be Mindful of Tornado Watch vs. Tornado Warning

Understand the difference between a tornado watch and a tornado warning. A tornado watch means that conditions are favorable for tornadoes to develop, while a tornado warning indicates that a tornado has been sighted or is imminent. Take immediate action when a tornado warning is issued.

In conclusion, the outdated advice of opening windows during a tornado has been debunked by scientific research and real-life observations. Tornadoes generate powerful winds and flying debris, which can cause significant damage to structures and pose a threat to personal safety. Instead of opening windows, the priority during a tornado warning should be to seek shelter in interior rooms away from windows. By understanding the science behind tornado damage and following tornado safety guidelines, we can minimize the risks and protect ourselves during severe weather events. Stay informed, be prepared, and prioritize your safety above all else when faced with a tornado threat.

Additional Information: Remember to stay tuned to local authorities and follow their instructions during severe weather events. Always prioritize personal safety and seek shelter in designated areas recommended by emergency management officials.
