Lightning Safety During Heat Waves: Essential Guidelines

Heat waves and thunderstorms are common in the United States, especially during summer months. Understanding lightning safety during these events is crucial to protect yourself and others.

What Are Heat Waves and Thunderstorms?

Heat Waves: Extended periods of abnormally hot weather, typically lasting more than two days, can lead to heat-related illnesses and strain infrastructure. (weather.gov)

Thunderstorms: Storms characterized by lightning, thunder, heavy rain, and sometimes hail. They can develop rapidly and pose significant risks, including lightning strikes.

How Do Heat Waves and Thunderstorms Relate?

Heat waves can create conditions conducive to thunderstorms. The intense heat causes air to rise, leading to cloud formation and potential storm development. This combination increases the likelihood of lightning activity.

What Are the Risks of Lightning During Heat Waves?

Lightning is a leading cause of weather-related fatalities in the U.S., averaging 47 deaths annually. (weather.gov) During heat waves, the risk is heightened due to increased outdoor activities and the rapid development of thunderstorms.

How Can You Stay Safe During Heat Waves and Thunderstorms?

1. Monitor Weather Conditions:

Regularly check local forecasts and stay informed about potential heat waves and thunderstorms. Use reliable sources like the National Weather Service for updates.

2. Seek Shelter Promptly:

At the first sign of a thunderstorm, move indoors. The safest places are substantial buildings with wiring and plumbing or hard-topped vehicles. Avoid open structures like sheds or pavilions. (weather.gov)

3. Avoid Water and Electrical Appliances:

Do not use corded phones, electrical equipment, or plumbing during a thunderstorm, as lightning can cause electrical surges. Cell phones and cordless phones are safe to use. (weather.gov)

4. Stay Away from Windows and Doors:

Keep away from windows and doors to prevent injury from potential glass breakage due to strong winds or hail.

5. Wait 30 Minutes After the Last Thunder:

Remain indoors for at least 30 minutes after the last clap of thunder before resuming outdoor activities. (weather.gov)

Fact: Heat lightning is simply lightning from a distant thunderstorm; it still poses a risk if you're within range. (weather.gov)
