What makes lightning so dangerous?
Lightning can strike several miles away from a storm, even when skies overhead appear clear. Meteorologists say if thunder can be heard, lightning is close enough to pose a threat.
A lightning bolt can reach temperatures of 50,000°F, five times hotter than the surface of the sun, and carries enough energy to cause cardiac arrest, burns and nervous system damage.
When is lightning most likely to strike?
Lightning is most common during the spring and summer months, especially in the afternoon and evening when thunderstorms are more likely to develop.
However, it can occur at any time of year when thunderstorms are present.
What is the safest place to be during a lightning storm?
The safest place is inside a substantial building with wiring and plumbing, or inside a hard-topped vehicle.
Small shelters, dugouts, tents and open structures do not provide adequate protection.
What should you avoid during a thunderstorm?
Meteorologists recommend avoiding:
- Open fields, hilltops and elevated areas
- Isolated trees or tall objects
- Bodies of water, including pools and lakes
- Metal objects such as fences, bleachers and golf clubs
Indoors, people should avoid using corded electronics, plumbing and electrical appliances, as lightning can travel through wiring and pipes.
What is the “30-30 rule”?
The “30-30 rule” is a simple way to gauge lightning danger:
- If the time between seeing lightning and hearing thunder is 30 seconds or less, seek shelter immediately
- Wait at least 30 minutes after the last thunder before going back outside
Is it safe to use a phone during a lightning storm?
Cordless and cell phones are generally safe to use.
However, using corded phones is not recommended because they can conduct electricity if lightning strikes nearby.
What should you do if you are caught outside?
As a last resort, if no shelter is available:
- Crouch down with your feet together, head tucked and ears covered
- Stay away from tall objects and water
- Spread out if in a group to reduce multiple injuries
The priority is to find a proper shelter as quickly as possible.
Can lightning strike the same place twice?
Yes. Lightning frequently strikes the same tall or isolated objects multiple times, especially buildings, towers and trees.
What should you do if someone is struck by lightning?
Call 911 immediately.
People struck by lightning do not carry an electrical charge and are safe to touch. Begin CPR if the person is not breathing and continue until help arrives.
How can you prepare before storms develop?
- Check weather forecasts and alerts before heading outdoors
- Have a plan to reach shelter quickly
- Monitor warnings through the News On 6 Weather App
