Conduct periodic drills, so everyone remembers what to do when a tornado is approaching. Go to safety immediately. Listen to local radio and TV stations for further updates. Be alert to changing weather conditions. Blowing debris or the sound of an approaching tornado may alert you.
Many people say it sounds like a freight train.
If you are inside, go to the safe place you picked to protect yourself from glass and other flying objects. The tornado may be approaching your area. If you are outside, hurry to the basement of a nearby sturdy building or lie flat in a ditch or low-lying area. Watch out for fallen power lines and stay out of the damaged area. Listen to the radio for information and instructions.
