Thunder & Lightning

All thunderstorms are dangerous. Every thunderstorm produces lightning. In the United States, an average of 300 people are injured and 80 people are killed each year by lightning. Although most lightning victims survive, people struck by lightning often report a variety of long-term, debilitating symptoms. Other associated dangers of thunderstorms include tornadoes, strong winds, hail, and flash flooding. Flash flooding is responsible for more fatalities—more than 140 annually—than any other thunderstorm-associated hazard.

Dry thunderstorms that do not produce rain that reaches the ground are most prevalent in the western United States. Falling raindrops evaporate, but lightning can still reach the ground and can start wildfires

"If thunder roars, go indoors."

No place outside is safe when lightning is in the area. Stay indoors until 30 minutes have passed after you hear the last clap of thunder.

Lightning Safety Tips for Inside the Home

• Avoid contact with corded phones
• Avoid contact with electrical equipment or cords. If you plan to unplug any electronic equipment, do so well before the storm arrives.
• Avoid contact with plumbing. Do not wash your hands, do not take a shower, do not wash dishes, and do not do laundry.
• Stay away from windows and doors, and stay off porches.
• Do not lie on concrete floors or lean against concrete walls.

If a Thunderstorm is Likely in Your Area

• Postpone outdoor activities.
• Get inside a home, building, or hard top automobile (not a convertible). Although you may be injured if lightning strikes your car, you are much safer inside a vehicle than outside.
• Remember, rubber-soled shoes and rubber tires provide NO protection from lightning. However, the steel frame of a hard-topped vehicle provides increased protection if you are not touching metal.
• Secure outdoor objects that could blow away or cause damage.
• Shutter windows and secure outside doors. If shutters are not available, close window blinds, shades, or curtains.
• Avoid showering or bathing. Plumbing and bathroom fixtures can conduct electricity.
• Use a corded telephone only for emergencies. Cordless and cellular telephones are safe to use.
• Unplug appliances and other electrical items such as computers and turn off air conditioners. Power surges from lightning can cause serious damage.
• Use a battery-operated NOAA Weather Radio for updates from local officials.

Stay away from:

• Natural lightning rods such as a tall, isolated tree in an open area.
• Hilltops, open fields, the beach, or a boat on the water.
• Isolated sheds or other small structures in open areas.
• Anything metal—tractors, farm equipment, motorcycles, golf carts, golf clubs, and bicycles.
