The Dangers of Hiding Under an Overpass During a Tornado: Why You Shouldn’t Wait for a Better Shelter

Tornadoes are nature's most violent storms, characterized by a rotating column of air extending from a thunderstorm to the ground. Seeking shelter during a tornado can save your life, but it's crucial to know where true safety lies. One common misconception is that hiding under an overpass can provide protection. However, this practice is incredibly dangerous and can lead to serious injuries or even death. This article will explain why hiding under an overpass during a tornado is a risky strategy and provide better alternatives.

Why Shouldn’t You Hide Under an Overpass?

Wind Tunnel Effect

Underpasses and bridges can create a wind tunnel effect, squeezing wind into a smaller space and increasing its speed. The wind can reach speeds that exceed 200 mph, making even a small space highly dangerous. Vehicles parked under these structures are not safe; they can also be lifted and carried by the powerful winds. The confined space under the overpass is an even more perilous location as it concentrates the force of the wind, acting as a funnel for debris.

Debris and Flying Objects

The most immediate danger from a tornado is debris. Powerful winds can pick up and carry objects at incredible speeds, causing severe injuries or fatalities. Venturing into the narrow space under an overpass places you directly in harm's way. Even if the winds are not powerful enough to lift your vehicle, the debris can still pose a significant threat. The smaller the space, the faster the wind can send debris through it, increasing the risk of injury.

Wind Direction and Speed Changes

During a tornado, the wind direction and speed can change dramatically. Climbing up to seek shelter under an overpass exposes you to higher wind speeds and more flying debris. The overpass acts as a funnel, channeling the wind into a smaller passage, which further intensifies the wind speeds. This setup is inherently dangerous and can lead to serious injuries or death.

Lack of Protection

Most overpasses lack the structural integrity to serve as a safe refuge during a tornado. There are no handholds or support beams to help you hold on during strong winds. The narrow passage under the overpass can also cause an increase in wind speed, making it an even more treacherous location.

What Should You Do Instead?

The best alternative to hiding under an overpass is to seek a sturdy shelter. If you are in a vehicle, staying in your car with the seatbelt on, lying down with your head below the window, and covering your head with a blanket offers some protection. If you can safely get lower than the roadway, exit your vehicle and lie in a small ditch or lie down in a doorway or basement, protecting your head with your hands. However, if none of these options are available, your best bet is an underground shelter, a basement, or a small windowless interior room in the lowest level of a sturdy building.

Conclusion

The safety during a tornado is paramount, and the location of your shelter is crucial. Hiding under an overpass during a tornado can be extremely dangerous. Opt instead for a sturdy shelter, a vehicle with safety measures, or an underground shelter. Remember, the safest place to be during a tornado is underground, and the next best option is indoors, preferably in a small, windowless room. Stay informed, prepare, and stay safe!
