Stay tuned for storm watches and warnings
When there are thunderstorms in your area, turn on your radio or TV to get the latest emergency information from local authorities. Listen for announcements of a tornado watch or tornado warning.
Local warning system
Learn about the tornado-warning system of your county or locality. Most tornado-prone areas have a siren system. Know how to distinguish between the siren's warnings for a tornado watch and a tornado warning.
A tornado watch is issued when weather conditions favor the formation of tornadoes, for example, during a severe thunderstorm.
During a tornado watch:
- Stay tuned to local radio and TV stations or a National Oceanographic and Atmospheric Administration (NOAA) Weather Radio for further weather information.
- Watch the weather and be prepared to take shelter immediately if conditions worsen.
A tornado warning is issued when a tornado funnel is sighted or indicated by weather radar. You should take shelter immediately.
Because tornadoes often accompany thunderstorms, pay close attention to changing weather conditions when there is a severe thunderstorm watch or warning.
- A severe thunderstorm watch means severe thunderstorms are possible in your area.
- A severe thunderstorm warning means severe thunderstorms are occurring in your area.
Keep fresh batteries and a battery-powered radio or TV on hand. Electrical power is often interrupted during thunderstorms – just when information about weather warnings is most needed.
Important measures to take
- Take a few minutes with your family to develop a tornado emergency plan. Sketch a floor plan of where you live, or walk through each room and discuss where and how to seek shelter.
- Show a second way to exit from each room or area. If you need special equipment, such as a rope ladder, mark where it is located.
- Make sure everyone understands the siren warning system, if there's such a system in your area.
- Mark where your first-aid kit and fire extinguishers are located.
- Mark where the utility switches or valves are located so they can be turned off – if time permits – in an emergency.
- Teach your family how to administer basic first aid, how to use a fire extinguisher, and how and when to turn off water, gas and electricity in your home.
- Learn the emergency dismissal policy for your child's school.
- Make sure your children know:
- What a tornado is
- What tornado watches and warnings are
- What county or parish they live in (warnings are issued by county or parish)
- How to take shelter, whether at home or at school
Extra measures for people with special needs
- Write down your specific needs, limitations, capabilities and medications. Keep this list near you always – perhaps in your purse or wallet.
- Find someone nearby (a spouse, roommate, friend, neighbor, relative or co-worker) who will agree to assist you in case of an emergency. Give them a copy of your list. You may also want to provide a spare key to your home or directions to find a key.
- Keep aware of weather conditions through whatever means are accessible to you. Some options are closed-captioning or scrolled warnings on TV, radio bulletins or call-in weather information lines.
Practicing your emergency plan
Conduct drills and ask questions to make sure your family remembers information on tornado safety, particularly how to recognize hazardous weather conditions and how to take shelter.
Writing down important information
Make a list of important information. Include these on your list:
- Make a list of important information. Include these on your list:
- Names, addresses and telephone numbers of your insurance agents, including policy types and numbers
- Telephone numbers of the electric, gas and water companies
- Names and telephone numbers of neighbors
- Name and telephone number of your landlord or property manager
- Important medical information (for example, allergies, regular medications and brief medical history)
- Year, model, license plates and identification numbers of your vehicles (automobiles, boats and RVs)
- Bank's or credit union's telephone number, and your account numbers
- Radio and TV broadcast stations to tune to for emergency broadcast information
Storing important documents
Store the following documents in a fire- and water-proof safe:
- Birth certificates
- Ownership certificates (autos, boats, etc.)
- Social-security cards
- Insurance policies
- Household inventory
- List of contents of household; include serial numbers, if applicable
- Photographs or videotape of contents of every room
- Photographs of items of high values, such as jewelry, paintings, collection items
Purchase a first-aid kit so your supplies will be easy to carry and be protected from water. Inspect your kit regularly and keep it freshly stocked.
Drugs and medications
- Hydrogen peroxide to wash and disinfect wounds
- Antibiotic ointment
- Individually wrapped alcohol swabs
- Aspirin and non-aspirin tablets
- Prescriptions and any long-term medications (keep these current)
- Diarrhea medicine
- Eye drops
NOTE: Important medical information and most prescriptions can be stored in the refrigerator, which provides excellent protection from fires.
- Clean sheets, torn into strips
- Elastic bandages
- Rolled gauze
- Cotton-tipped swabs
- Adhesive tape roll
Other first-aid supplies
- First-aid book
- Writing materials
- Bar soap
- Paper cups
- Plastic bags
- Safety pins
- Needle and thread
- Instant cold packs for sprains
- Sanitary napkins
- Pocket knife
- Splinting material
Reducing household hazards
The following suggestions will reduce the risk for injury during or after a tornado. No amount of preparation will eliminate every risk.
Inspect your home for possible hazards, including the following:
- Are walls securely bolted to the foundation?
- Are wall studs attached to the roof rafters with metal hurricane clips, not nails?
- Do you know where and how to shut off utilities at the main switches or valves?
- Are chairs or beds near windows, mirrors or large pictures?
- Are heavy items stored on shelves more than 30" high?
- Are there large, unsecured items that might topple over or fall?
- Are poisons, solvents or toxic materials stored safely?
Securing your home's structure
No home is completely safe in a tornado. However, attention to construction details can reduce damage and provide better protection for you and your family if a tornado should strike your house. If an inspection using the "Home Inspection Checklist" reveals a possible hazard in the way your home is constructed, contact your local city or county building inspectors for more information about structural safety. They may also offer suggestions on finding a qualified contractor to do any needed work for you.
Shutting Off Utilities
After a tornado, DO NOT USE matches, lighters or appliances, and do not operate light switches until you are sure there are no gas leaks. Sparks from electrical switches could ignite gas and cause an explosion.
If you smell the odor of gas or if you notice a large consumption of gas being registered on the gas meter, shut off the gas immediately. First, find the main shut-off valve located on a pipe next to the gas meter. Use an adjustable wrench to turn the valve to the "off" position.
After a major disaster, shut off the electricity. Sparks from electrical switches could ignite leaking gas and cause an explosion.
- Water may be turned off at either of two locations:
Attach a valve wrench to the water line. (This tool can be purchased at most hardware stores.)
Label the water mains for quick identification.
- At the main meter, which controls the water flow to the entire property
- At the water main leading into the home: If you may need an emergency source of fresh water, it is better to shut off your water here, because it will conserve the water in your water heater.
Arranging and securing household items
- Arrange furniture so that chairs and beds are away from windows, mirrors and picture frames.
- Place heavy or large items on lower shelves.
- Secure your large appliances, especially your water heater, with flexible cable, braided wire or metal strapping.
- Identify top-heavy, free-standing furniture, such as bookcases and china cabinets that could topple over.
- Secure your furniture by using one of two methods.
Install sliding bolts or childproof latches on all cabinet doors.
Store all hazardous materials such as poisons and solvents:
- "L" brackets, corner brackets or aluminum molding, to attach tall or top-heavy furniture to the wall.
- Eyebolts, to secure items located a short distance from the wall.
- in a sturdy, latched or locked cabinet
- in a well-ventilated area
- away from emergency food or water supplies
