Before
- Conduct tornado drills each tornado season.
- Designate an area in the home as a shelter, and practice having everyone in the family go there in response to a tornado threat.
- Discuss with family members the difference between a tornado watch and a tornado warning. Contact your local emergency management office or American Red Cross chapter for more information on tornadoes.
Have disaster supplies on hand, including the following:
ü Flashlight and extra batteries
ü Portable, battery-operated radio and extra
ü batteries
ü First aid kit and manual
ü Emergency food and water
ü Nonelectric can opener
ü Essential medicines
ü Cash and credit cards
ü Sturdy shoes
ü Cellular phone (if you have one)
- If family members are separated during a tornado (you might be at work and children might be at school), have a plan for getting back together.
- Ask an out-of-state relative or friend to serve as the “family contact.” After a disaster, it’s often easier to call long distance. Make sure everyone in the family knows the name, address, and phone number of the contact person. Have a backup “family contact” in case the first one is not available.
During
At home:
· Go at once to the basement, storm cellar, or the lowest level of the building.
· If there is no basement, go to an inner hallway or a smaller inner room without windows, such as a bathroom or closet.
· Get away from the windows.
· Go to the center of the room. Stay away from corners because they tend to attract debris.
· Get under a piece of sturdy furniture, such as a workbench or heavy table or desk, and hold on to it.
· Use your arms to protect your head and neck, or use a heavy blanket, pillow, etc., to help protect you and to cover your head.
· If you are in a mobile home, get out and find shelter elsewhere.
At work or school:
· Go to the basement or to an inside hallway at the lowest level.
· Avoid places with wide-span roofs, such as auditoriums, cafeterias, large hallways, or shopping malls.
· Get under a piece of sturdy furniture, such as a workbench or heavy table or desk, and hold on to it.
· Use your arms to protect your head and neck.
Outdoors:
· If possible, get inside a building.
· If shelter is not available or there is no time to get indoors, lie in a ditch or low-lying area or crouch near a strong building. Be aware of the potential for flooding.
· Use your arms to protect your head and neck.
In a car:
§ Never try to out-drive a tornado in a car or truck. Tornadoes can change direction quickly and can lift and toss your vehicle through the air.
§ Leave the car immediately, and take shelter in a nearby building.
§ If there is no time to get indoors, get out of the car and lie in a ditch or low-lying area away from the vehicle. Be aware of the potential for flooding.
After
- Help injured or trapped persons
- Give first aid when appropriate. Don’t move the seriously injured unless they are in immediate danger of further injury. Call for help.
- Turn on radio or television to get the latest information.
- Stay out of damaged buildings. Return home only when authorities say it is safe.
- Use the telephone only for emergency calls.
- Clean up spilled medicines, bleach, gasoline, or other flammable liquids immediately. Leavec the building if you smell gas or chemical fumes.
- Take pictures of damage to the house and its contents for insurance purposes.
- Remember to help neighbors who may require special assistance like people with infants, the elderly, and people with disabilities.

Tornado FAQ's
Tornadoes come from the energy released in a thunderstorm. As powerful as they are, tornadoes account for only a tiny fraction of the energy in a thunderstorm. What makes them dangerous is that their energy is concentrated in a small area, perhaps only a hundred yards across. Not all tornadoes are the same, of course, and science does not yet completely understand how part of a thunderstorm's energy sometimes gets focused into something as small as a tornado..
How fast can a tornado go?
We're not really sure what the highest wind speed might be inside a tornado. Since strong and violent tornadoes destroy weather instruments, we really only have measurements of the winds inside weaker tornadoes. Mobile Doppler radars can measure wind speeds in a tornado above ground level -- and the strongest was 318 mph measured on May 3, 1999 near Bridge Creek/Moore, Oklahoma.
People who study tornadoes are just research meteorologists. You may have heard another term - storm chaser - but that really refers to people who chase tornadoes for a hobby. Research meteorologists do science. They have to come up with questions they think they can answer by taking certain measurements.
Detailed statistics about the time a tornado is on the ground are not available. This time can range from an instant to several hours. The average is about five minutes.
