Although lighting can happen at any time of the year, lightning strikes most often during summer months. So far this year, there have been 26 people reported to have been struck by lightning; 12 of those people died.
It might be cool to look at from a safe distance, but lightning kills more than 20 people each year in the United States and injures hundreds more — with some survivors suffering lifelong neurological damage. One thing that is for certain: No place outside is safe during a thunderstorm.

What else should you know about this electrical wonder of nature? We debunk 5 popular myths with science-backed facts about this dangerous and often misunderstood phenomenon.
Myth #1: A tree can act as sufficient shelter during a thunderstorm.
Fact: No. Standing underneath or near a tree is the second most dangerous place to be during a thunderstorm; the most dangerous is being outside in an open space. An enclosed building with wiring and plumbing is the safest place to be during a storm. Remember: Trees, sheds, picnic shelters, tents or covered porches will not protect you from lightning.
Myth #2: Lightning victims carry an electrical charge. If you touch them, you can be electrocuted.
Fact: Not true. The human body does not store electricity. If you are able to, you should give a lightning victim first aid and/or immediately call 911. This is the most chilling of lightning myths because it could be the difference between life and death.

Myth #3: If you are trapped outside during a thunderstorm, crouching down will reduce your risk of being struck by lightning.
Fact: No. Crouching down will not make you any safer. If you are stuck outside during a storm, keep moving toward a safe shelter.

Myth #4: Lightning never strikes in one place twice.
Fact: Actually, lightning can, and often does, strike the same place repeatedly — especially if it’s a tall and isolated object. For example, the Empire State Building is hit about 25 times per year.
Here’s more from the National Weather Service:
Myth #5: Lightning cannot strike in an area if it is not raining and skies are clear.
Fact: Not true. Do not wait until a thunderstorm is immediately overhead and for rain to begin to act. If you can hear thunder, lightning is close enough to pose an immediate threat, even if the sky above you is blue. If thunder roars, seek shelter immediately.
Bottom line: NOAA debunks five popular myths about lightning.
