Just like a fire, an earthquake or an automobile accident, a tornado is a low probability, high impact event. Chances are, you will never experience a tornado. Even if you live in the heart of tornado alley, the chances that your house will be struck by a tornado are small. However, you need to be ready just in case. Your tornado safety plan is your safety belt, your smoke detector, your plan to survive when dangerous weather threatens.

This website is designed to give you information to help you prepare for severe thunderstorms and tornadoes.
