Twister: Discussion Question Answers

1. Below ground level and better avoids flying debris

2. (From NSSL) If you see a severe thunderstorm approaching, use a weather radio or battery-powered radio to find out if a tornado is approaching. Go to an inside wall on lowest floor, and kneel on the floor facing the wall, and put your hands over your head. When in school, stay away from rooms with wide roofs that could collapse easily, such as gyms and auditoriums. Don't use your phone, as it may conduct electricity to you. If you are at your home, go to the basement and get under the stairs or a piece of heavy furniture. If you don't have a basement, get in a closet in the middle of the house. If advance warning of a Tornado is given: If you are outside, go to the safest looking place (i.e., a ditch, etc.) If you are in a car, get out. Tornadoes can outrun fast cars.

3. If a Tornado may form, a Tornado Watch will be issued. If a Tornado has been sighted, a Tornado Warning will be issued.

4. Thunderstorms, hail, rain, low pressure (answers will vary)

5.
