How to survive a tornado
It is often said that tornadoes are nature's most violent storms. When a tornado strikes, your every choice can mean the difference between life and death.
Surviving in a building
Move immediately to an underground shelter, whenever possible. At the first sign of a tornado, or if a tornado warning has been issued, stop whatever you're doing and seek appropriate shelter immediately, even if you don't see a tornado. A warning means an actual tornado has been sighted or indicated by radar.
Sample
While writing
Stay in a windowless room on the lowest level, if you can't go underground. In a building with no basement, avoid windows and go to the lowest floor. Alternatively, seek shelter in a small room that is located near the center of the house, under a stairwell, or in an interior hallway with no windows. Regardless of where you are, crouch low to the ground or lie down, face down and cover your head with your hands and arms. Take cover under a strong table if possible, and cover yourself with a mattress, cushions, or blankets.
While writing
Know where not to seek shelter. Not all hiding spots are created equally. The following locations should be your absolute last resort during a tornado, as they all have the potential to be severely damaged by high winds.
Surviving out in the open
Know the warning signs of potential tornadoes. Being able to quickly determine your risk is one of the key steps to finding shelter and surviving. Unfortunately, there are few proven ways to stay safe in the open if caught in a tornado, and the number one advice is to find shelter as soon as you see these warning signs. Most tornadoes are accompanied by thunderstorms, hail, and, of course, high winds, but there are other things to look out for as well.
While writing
Drive, if possible, to the nearest shelter. If you hear the warning and it is still safe to drive, get to the closest building you can find. Keep your seat belt on and get off the open road as soon as you can. Turn on your high beams and move immediately to some sort of structure, preferably with a basement. You are almost always better off in a building than in your car.
Preparing for a tornado
Pay attention to tornado watches and warnings. A tornado watch means that there is a threat of tornadoes within your area and that you should keep an eye on the news. A tornado warning is much more serious. Tornado warnings mean that a sign of rotation has been detected and that you should take immediate action depending on the tornado's location and its predicted track.
While writing
Craft an emergency plan in your house. Make a plan for where to go during a tornado. Have this plan in place and practiced before you need it. Everyone you live with should know exactly which room of the house to go to in the event of a tornado. Make sure that this room is stocked with all necessary provisions.
