The main reasons Louisiana experiences a high number of tornadoes is its location and its weather conditions. The mixture of cold air from the Gulf of Mexico and warm air from tropical thunderstorms make Louisiana highly susceptible to tornadoes.
Tornadoes form when cold and dry air collides with warm and stable air. The cold and dry air mainly comes from the Gulf of Mexico, of which Louisiana shares a coastline. The warm and stable air comes from the tropical thunderstorms that shift toward Louisiana. Once the air collides, it becomes unstable, and a tornado breaks out.
How To Stay Safe During Tornadoes
Since Louisiana homes usually don’t have basements, its citizens have to follow different procedures to stay safe during tornadoes. The most important things to do are go to the lowest floor of the building and have an emergency kit prepared.
Before you take shelter, make sure you have a prepared emergency kit on hand. A few things to put in the emergency kit include:
- Water and food rations
- Battery powered radios or televisions
- Fresh batteries for the radio/TV
- A plan to follow for evacuation, if necessary
The emergency kit should be kept somewhere that’s easy to remember, such as a closet or supply room.
Louisiana houses typically don’t have basements because of the damp and unstable soil the land has. Since Louisiana citizens don’t have this shelter option, the tornado safety steps are to go to the lowest part of the building and avoid windows. If you can’t make it to the lower area of a building, a few other good places to take shelter from a tornado include:
- A closet or bathroom
- Under a stairwell
- An interior hallway with no windows
Once you find somewhere to take shelter, you can protect yourself from falling debris by covering yourself with something heavy and soft. The most effective covering from falling debris is an emergency blanket since they are thick and heavy. If you don’t have access to an emergency blanket, then a mattress or thick blanket is suitable.
The final step is to listen for updates on where the tornado is and how intense it is. You should not leave your shelter until the local weather service gives a complete all clear for the tornado.
Lafayette Parish, Louisiana, experiences the most tornadoes out of anywhere else in the state. Because of the frequency and how quickly tornadoes can appear, it can sometimes be hard to predict when one will hit the area. This is why it’s important to make sure you are prepared with an emergency kit and a plan to take shelter, just in case a tornado strikes.
