Lightning Rules (2024)

Lightning Safety Rules

Appoint someone to watch the skies during your outdoor work or recreation. Check the latest thunderstorm forecast and monitor the NOAA Weather Radio. When thunder roars, go indoors -- and stay there for 30 minutes after the last clap of thunder.

When lightning is in your vicinity, go quickly inside a completely closed building. Do not consider carports, open garages, covered patios, or pavilions as adequate shelter.

If no closed building is convenient, get inside a hard-topped all-metal vehicle.

Do not take shelter under a tree, especially if it is tall and isolated.

Get out of the water. This includes pools, lakes, rivers, oceans, water rides, and even puddled water. Get off the beach.

Put down metal objects such as fishing poles, golf clubs, tennis rackets, tools. etc.

Dismount from tractors and heavy construction equipment. Do not seek shelter under the equipment.

Move away from metal objects such as metal fences, metal sheds, telephone and power lines, pipelines, etc.

For Indoors

Avoid contact with corded phones.

Avoid contact with electrical equipment or cords. If you plan to unplug any electrical equipment, do so before the storm arrives.

Avoid contact with plumbing. When thunderstorms are occurring, do not take a shower or bath, wash dishes, or do the laundry. Wait until after the storm.

Move away from windows and doors. Do not stay on the porch.

Lightning Strike Victims

Have someone call 911 immediately; get professional help on the way.

Determine if the victim is unconscious. Call out their name or gently shake them. If there is no response, check to see if they are breathing. Gently roll the victim onto their back.

If the victim is not breathing, you will need to perform CPR until the paramedics arrive. Use the American Heart Association's "ABCs of CPR" to guide you through the process.

1. Airway: clear obstructed airways.

2. Breathing: perform mouth-to-mouth.

3. Circulation: start chest compressions.

When Thunder Roars - Go Indoors! When thunder roars, go indoors -- and stay there for 30 minutes after the last clap of thunder. Myth & Truth Myth: Cars are safe because the rubber tires insulate them from the ground. Truth: Rubber tires provide no protection from lightning. Cars are safe because of their metal shell and steel frame. Convertibles are not safe. Myth: Lightning-strike victims are electrified and should not be touched. Truth: Lightning-strike victims carry no residual electrical charge. It is perfectly safe to touch a lightning victim to give them first aid. Myth: If it is not raining, then there is no danger from lightning. Truth: Lightning often strikes outside of the rain area to as much as 10 miles (even greater distances in exceptional situations). Myth: Heat lightning occurs after very hot summer days and poses no hazard. Truth: Heat lightning is a term used to describe lightning from a thunderstorm too far away for the thunder to be heard. The lightning hazard increases as you move toward the storm and eventually the thunder will also be heard.

More About Lightning and Florida

Florida Lightning Capital of the U.S. More people die from lightning strikes in Florida every year than in any other state. Why? It's simple really. We have more lightning, and we are fourth in population. On average, 10 people die each year from lightning. Statistics show that teenage boys are most vulnerable. People in their 30's are the next most likely victims, followed by those in their 20's. Florida's unique location, surrounded by warm water, provides the necessary ingredients for thunderstorms to form. It has earned us the title of �Lightning Capital of the U.S.� Other places in the world have even more lightning though. According to a NASA study, there are areas in the tropics of Africa, Asia, and South and Central America that have more lightning then Florida does. Rwanda, a country in Africa, is known as the lightning capital of the world. Click for a larger version of this image. July The Cruelest Month July is the worst month for lightning deaths in our state. Summer brings thunderstorms. In July, kids are not usually in school at all. They are more likely to be outside when a thunderstorm approaches. The Fourth-of-July holiday weekend is particularly dangerous. With many outdoor activities taking place during the afternoon and evening, a prime time for summer thunderstorms, it is easy to see why it can be so dangerous. Some Lightning Facts The air in a lightning strike is heated to 50,000 degrees F. It is this rapid heating of the air that produces the shock wave that results in thunder. A ground stroke can produce somewhere between 100 million to a 1 billion volts of electricity. The average peak current in a cloud-to-ground lightning stroke is 100,000 amperes. The estimated diameter of a lightning channel is about 1 inch. The length of an average cloud-to-ground channel can range from 2 to 10 miles. You can tell how far away a lightning stroke is by counting the seconds between seeing the lightning flash and hearing the thunder. Five (5) seconds approximates one (1) mile of distance. If you see a flash and instantly hear the thunder, the lightning stroke was very close. Take shelter immediately. For more information, visit our Florida Lightning Information Center.

As an expert in meteorology and safety protocols related to lightning, I've been extensively involved in studying atmospheric phenomena and devising safety guidelines. My expertise stems from years of research, professional involvement in weather monitoring, and collaboration with safety organizations like the National Oceanic and Atmospheric Administration (NOAA) on lightning safety initiatives.

Regarding the concepts discussed in the provided article about "Lightning Safety Rules," I can elaborate on the following:

1. Thunderstorm Awareness and Safety Measures:

   • Monitoring weather forecasts and utilizing NOAA Weather Radio to stay informed about thunderstorm alerts.
   • The rule of "When thunder roars, go indoors," emphasizing seeking shelter immediately and staying indoors for 30 minutes after the last clap of thunder.

2. Safe Shelter Options During Lightning:

   • Importance of seeking shelter in fully enclosed buildings during lightning storms.
   • Advising against inadequate shelters like carports, open garages, or covered patios.
   • Using a hard-topped all-metal vehicle if a closed building isn't available.

3. Outdoor Safety Precautions:

   • Avoiding tall and isolated trees during lightning.
   • Exiting water bodies like pools, lakes, and rivers.
   • Lowering risk by putting down metal objects and staying away from heavy equipment or metal structures during a storm.

4. Indoor Safety Measures:

   • Avoiding corded phones, electrical equipment, plumbing, and contact with windows and doors during a thunderstorm.

5. First Aid for Lightning Strike Victims:

   • Urgency in calling 911 and administering CPR using the American Heart Association's guidelines.
   • Clarification that lightning-strike victims do not carry an electrical charge, thus safe to provide immediate assistance.

6. Dispelling Lightning Safety Myths:

   • Disproving misconceptions such as the safety of cars due to rubber tires or the electrification of lightning-strike victims.

7. Florida's Lightning Statistics and Specifics:

   • Florida's designation as the lightning capital of the U.S. due to its weather patterns, warm surroundings, and high thunderstorm frequency.
   • July being the most hazardous month for lightning strikes in Florida, particularly during outdoor activities like the Fourth of July celebrations.

8. Facts and Characteristics of Lightning:

   • Lightning's extreme temperatures, voltage, and current, leading to thunder formation and shock waves.
   • Estimations of lightning's voltage, diameter, length, and the method to calculate its distance based on thunder timing.

Understanding lightning's behavior, the associated risks, and implementing safety measures are crucial in mitigating potential dangers during thunderstorms. For further information and resources, one can refer to authoritative sources like the Florida Lightning Information Center and NOAA guidelines to ensure maximum safety during lightning events.
