Severe Weather Awareness Week: Lightning
Monday begins Florida’s Severe Weather Awareness Week, when we will cover a different topic in weather safety every day. Stay informed by following Florida Storms, the Florida Division of Emergency Management and your local National Weather Service office on social media.
Often considered the country’s lightning capital, Florida experienced 285 lightning events per square mile in 2022. It’s a common hazard, especially following sea breeze storms typical during summer months.
“It’s one of those hazards that just about everyone experiences,” said John Jensenius, Lightning Safety Specialist with the National Lightning Safety Council.
He also said everyone is making the same safety mistakes, across the county.
“If you hear thunder, you’re already in danger,” he said.
Jensenius said the first thing to do to protect yourself is to check the forecast first. Being caught in unexpected bad weather can be avoided simply by checking the forecast before you leave for an outdoor activity.
When you arrive Jensenius said, make sure there is a shelter nearby you could access in case of lightning. That can be either any indoor shelter or a hard-topped vehicle. Open air shelters and convertible vehicles are not substantial enough to protect against lightning.
He stressed there is nowhere safe outdoors if caught in a thunderstorm.
While outside, continue to monitor conditions and be ready to act if conditions change. Unfortunately, Jensenius said his research shows too many people are harmed after waiting too long to get to shelter.
Amy Godsey is the Chief Meteorologist for the Florida Division of Emergency Management. On the other hand, she said, many people may be too eager to head back outside.
“Once that rain has passed, some people are too quick to resume outdoor activities,” she said.
Lightning tends to strike the tallest object, she said, so if caught outdoors do not stand under tree cover to escape the rain or wind.
She also said it’s a myth that you will be electrocuted if you touch the victim of a lightning strike. Godsey said to immediately administer first aid and call 911 if you think someone has suffered a lightning strike.
In Florida 83 people have died from lightning strikes since 2006. 19 people died just in 2022. About half of that number, Jensenius said, were involved in leisure activities such as fishing or boating. The other half were involved in work related activities like roofing and landscaping. Men account for 80% of fatalities.
About one in ten people will die from a lightning strike. While lightning fatalities may be rare, the remaining nine out of ten survivors may be left with lifelong neurological problem because of cardiac arrest and a lack of oxygen to the brain. Others may be left with numbness or memory issues.
Jensenius said its important to understand how lightning works to stay safe. For example, you don’t need to be directly struck by lightning to be harmed.
“Lightning is simply looking for a connection,” Jensenius said, and it will try and make contact with anything within 150 feet of where it touches down.
Tall objects like trees or poles are farther from the Earth and might be first to be struck, but a person can be harmed by the ground surface current made when lighting contacts the ground.
Contrary to popular belief, neither water nor metal “attracts” lightning.
“Nothing really ‘attracts’ lightning,” Jensenius said.
Water is a conductor, however, said Godsey. Which is why it is so important to get out of the water and avoid using running water indoors during a storm. Metal is also a conductor, so stay away from fences, railing and bleachers.
And neither will be rubber in your sneakers nor the rubber in your car’s tires protect you, she adds.
Godsey said that while the National Weather Service does not issue warnings specific to lightning, there are other weather apps (such as the Florida Storms app) that can tell you when there has been a lightning strike in your vicinity.
“It’s on each individual person to be alert,” said Godsey.
