The Importance of Practicing Lightning Safety

by Suzanne Wiley, volunteer contributor


Are you the type that gets a kick out of rubbing a balloon on your younger sibling’s head to watch their hair stand up on end? No matter your age, it always looks hilarious, right? 

Have you ever experienced that same charge without rubbing a balloon on your head or after shuffling on the carpet and touching something metal? Way back when I was a silly little girl whose main concern was fun in the sun, my friend and I were swimming in a resort pool at the Lake of the Ozarks. Foreboding gray clouds had formed in the distance. We failed to realize we were putting ourselves in great danger. You see, a severe thunderstorm was brewing and the static electricity in the air was so intense, our hair was standing up on end just as if we had rubbed a balloon on each other’s heads. 

The clouds in the sky that day were statically charged with electricity—a clear sign to get out of the water and go inside. Luckily, we did become alarmed and went inside. Our child wonderment and amusement could have been cut short that day; lightning kills more Americans a year than tornados and hurricanes. The only other weather event that causes more fatalities is flooding. Indeed, NOAA isn’t wrong when they say that lightning is the most “underrated weather hazard.” 

Lightning Facts


Scientists and weather specialists are still trying to figure out lightning, but what we do know is that the mixture of a storm cloud’s water droplets and ice, air currents and ground evaporation cause turbulence inside the cloud, polarizing the cloud’s structure. Positive charges form in the upper part of the cloud, while negative charges form in the bottom. This reaction causes an electric charge not only in the cloud, but also on the ground below. When these two electrostatic charges meet, a lightning bolt strikes. 

A lightning bolt can hold up to 300 million volts of electricity and can heat the air around it five times hotter than the sun’s surface. Every day around the world there is an estimated 2,000 thunderstorms. All thunderstorms produce lightning. On average, that is eight million lightning strikes a day. 

It does not necessarily have to be cloudy and rainy for lightning to strike, either. Lightning has the capability to strike 10 miles away from its originating thunderstorm. If you hear thunder—the sound lightning makes—you can be struck. (We see lightning before we hear it, because light travels faster than sound.) Even 30 minutes after a storm passes, you can still be struck by lightning, so stay indoors or in your shelter 30 minutes after you hear the last round of thunder, or see the last lightning strike. 

There are many myths floating around about lightning safety. Did you know that many victims of lightning strikes were either standing under a tree or in their garage? Though lightning is not attracted to any certain item, like a metal fence, there are many good conductors for electricity—water, concrete and metal being the top conductors. There are three factors that go into where lightning strikes—height, space and isolation. One thing that is true about lightning—it tends to hit the tallest thing around.

Even though only about 10 percent of the 400 Americans hit by lightning a year die, more than half suffer long-term devastating effects such as brain damage, memory loss, and severe burns. Over your lifetime, you have a one in 3,000 chance of being struck by lightning. But here is the good news: most lightning strikes are completely avoidable! Don’t wait too long to seek shelter like I did as a kid. If clouds form and it turns dark, you see lightning or hear thunder seek shelter right away—not “just after this inning.” 

When Thunder Roars, Go Indoors! 


Whatever you do, do not stay out in the soccer field or baseball diamond. When storm clouds form, you hear thunder or see lightning seek shelter indoors. Baseball dugs out, concrete bathrooms or picnic table shelters and shades are not safe. Lightning travels through concrete. Your best bet is to seek shelter in a building with electricity and plumbing. Like I said above, it is true what you have always been told, lightning will strike the tallest thing, so don’t be the tallest thing, nor stand under the tallest thing. The second leading cause of lightning strike fatalities is due from standing under a tree. If your only option is trees, do not pick a large, isolated tree. Seek shelter under a small cluster of shorter trees. And for goodness sake’s put down your umbrella! That metal tip at the top might just as well be Benjamin Franklin’s lightning rod! 

Bring your pets inside, as well. Doghouses will not protect your pet. While inside, do not shower, bathe, wash dishes, or use a corded phone. Lightning can travel through wires. Stay away from windows and go all the way inside if you are in the garage. Cell phones and battery-operated electronics are safe to use during a lightning storm. Listen to the weather, turn on your NOAA-approved emergency weather alert radio, or download the American Red Cross app to stay current on when it is safe to go back outside. It is definitely not the time to fly a kite, raise a flagpole, or wear your 5-inch heels. 

If you are outside and nowhere near home, your car, as long as it is not a convertible and the windows are rolled up is a safe place to seek shelter from a lightning storm. If no inside shelter or vehicle is accessible, do not remain in an open field, try to pick a wooded area and assume the “lightning position.” This position will not guarantee you will not be hit, but you have a better chance of remaining safe. To assume the lightning position, squat or crouch down on your feet. Roll up with your feet together, head down and wrap your arms around your knees. Do NOT lie down. 

Get off and out of the water immediately if you are swimming or boating and seek shelter indoors. If you happen to be too far out from shore, stop all activities such as tubing, skiing, or swimming, and go into the cabin of the boat. For boats without cabins, crouch down in the bottom. Do not touch any of the electronics in the boat. If you do not have a lightning protection system, remove or lower all metal poles, like the antenna or lights. Do not touch two different metal things at the same time. 

It is safe to touch someone hit by lightning. You will not get shocked. They need immediate help. Perform CPR if necessary and call 911. 

Because of the frequency of thunderstorms and increase in outdoor activities, summer is peak season for lightning. To be safe, always pay attention to the weather, and cancel any outdoor activities if there is any threat of thunderstorms.

National Weather Service Urges Preparedness as Second Storm Season Approaches

by Anita Foster, Chief Communications Officer, American Red Cross North Texas 

As we saw with the tornadoes and storms that hit the Great Plains this past weekend, severe weather isn't just for spring. In fact, we're entering into what’s known as the second severe storm season of the year. Yes, there really is a second storm season! To learn more about this topic and others, I sat down with Tom Bradshaw, Meteorologist in Charge, at the National Weather Service in Fort Worth, Texas for a conversation about—well, the weather. 
Tom Bradshaw, Meteorologist in Charge, NWS

Winds & Floods

“People need to plan now for upcoming storms that can be just as strong as what we see in the spring,” said Bradshaw. “Typically, we hit a second storm season around September and October. While the storms aren’t as frequent, they can have the same deadly results as we saw this year in Granbury and Moore, Oklahoma.” 

Bradshaw points out that one of the biggest concerns during the fall severe storm season, in addition to wind and hail, is flooding. “We tend to see the biggest flood events happen in the fall, especially when we’re in drought seasons, which we are in now here in this area. Unfortunately, most droughts end in floods.” Stay flood safe this season by following these tips

An Unusual Pattern

Coming from western Oklahoma, Bradshaw is accustomed to communities being ready for big supercell thunderstorms, but here in North Texas, the past two years have been eye-opening. 

“We’ve had everything from large hail, damaging winds, even 10-20 tornadoes at a time here in North Texas just in the past two years,” Bradshaw reflected. “The images of 18-wheelers flying through the air and the neighborhood in Granbury pretty much leveled—that’s the kind of weather that hits this area about once a decade so it’s been unusual.” 

Because Mother Nature has a mind of her own, it’s critical that North Texans do make severe weather plans while the sky is blue. One area to talk about ahead of time is what to do if you’re kids are at school and severe weather is approaching. 

Schools & Preparedness

“After seeing what happened when the tornadoes hit the schools in Oklahoma, it’s clear there aren’t easy answers about what parents should do,” said Bradshaw. “But 99 out of 100 times, schools are safer than most places.” 

Bradshaw encourages everyone to think through what they would do if their kids are in school before the storm approaches. “Talk to the schools ahead of time, be sure they have a tornado plan. Comfort yourself with that information because it will help you to know that the school has your kids best interests at heart and that they know what to do to keep them safe.” He goes on to say that chaos can actually be created if everyone rushes to schools to pick up their kids. “If everyone descends on the schools, suddenly there’s a massive traffic back-up with a storm coming. You don’t want to lose those precious moments to stay safe.” 

If you’re kids school isn’t as prepared as you would like, point them to this reference page to help them be even better prepared before the next storm. 

Driving & Tornadoes

One frequently asked question we get at the Red Cross is if you should get in your car and drive somewhere if a storm is coming and you don’t have a safe shelter. Bradshaw gave great advice on the subject: 

“If you don’t feel safe where you are, and you are confident you have time, get in your car and drive to a safe place.” But he also warns that you should never leave during the storm. Once a tornado warning has been issued, it’s too late to make an alternate plan. “Identify, in advance, exactly where you’re going to go. But when in doubt, stay put.” 

CASA Radar Initiative

While we’re busy preparing as families during National Preparedness Month, the National Weather Service is doing the same as an organization with the new CASA Radar Initiative. In a nutshell, this complex radar system moves radars closer to the ground so that meteorologists can see the evolution of rotation. “We’re hoping to have about four of these new radars by the fall,” said Bradshaw. “By seeing the rotation closer up, we have better tools to warn the public.” 

If you’ve got six minutes to spare and like us, have a fascination with the weather, check out this awesome video about the new CASA radars. It features some of our favorite meteorologists including Rebecca Miller, David Finfrock and Larry Mowry. 

It’s Not “If,” But When

It was eerie to hear Bradshaw state the same thing we do every day at the Red Cross, and it’s why we talk to you so often about preparedness….it’s not a matter of “if” the Metroplex will be impacted by a storm system like the one that hit in Moore, Oklahoma, it’s just a matter of when. 

“The toll that a storm system like that would take on this densely populated Metroplex is immeasurable,” said Bradshaw. “We have well over six million people in the metropolitan area. The impact of an EF-4 or EF-5 tornado would be massive.” 

Before an emergency, work with your family to develop your comprehensive tornado safety plan

Prepare Now

Whether tornadoes, floods, heat waves or the unknown, we can all do our part to prepare. Take some time to create a checklist of things that you and your family should do in the event of an emergency. Things like packing a disaster supplies kit or talking about your family communication plan. If you’re getting ready for work or school in the morning and you hear that severe weather may be possible during the day, stick close to your radio, internet connection or mobile device. Follow @RedCrossDFW, @NWSFortWorth and your favorite meteorologists on Twitter for real-time information during storms. Think about what you’ll do if you’re in a mobile home, caught out on the road or separated from your family. 

The American Red Cross has a wealth of information on how to prepare at www.redcross.org. You can also visit the National Weather Service to check out the daily weather at http://www.srh.noaa.gov/fwd

It Happens in a Flash: Lightning Safety Tips

by Cathryn Homier, volunteer contributor


Take a minute, and think of someone you know who buys lottery tickets. Maybe it’s no one close to you. Maybe it’s just someone you’ve seen buying tickets the same time you’ve been inside a convenience store. Now consider this: that person is more likely to get struck by lightning once in their lifetime (1 in 10,000 over 80 years) than win the mega millions jackpot.

Despite the odds, people still play the lottery. But, what about lightning safety? With potentially far greater stakes at risk, all of us, including you – yes, you, even if you don’t play the mega millions – should brush up on the best ways to stay safe when lightning is near. 

While we can all be thankful that summertime thunderstorms keep scorching heat at bay, they also mean lightning is present. Summer is when most of lightning injuries occur: the amount of time people spend outdoors is at its highest, as is lightning activity. Don’t gamble with your safety. If you hear thunder, you are within 10 miles of a storm, and potentially in danger from lightning. Wait 30 minutes from the last thunder clap before venturing back outside.

Plan ahead. If you’re going to be outside, check the weather. Do whatever you can to not be caught outside during a thunderstorm. If you are, remember the only truly safe action is to get inside a safe building or a vehicle. Baseball dugouts, tents, and open sided picnic shelters are not completely safe during lightning activity.

Don’t shelter under an isolated tree. Lightning tends to strike the tallest object in its path, making trees or lightning rods especially susceptible to being hit. If you have no safe building nearby, it’s best to stay near a lower stand of trees. Never lie flat on the ground if you’re caught outdoors. 

Don’t touch electrical equipment or cords. This also goes for corded landline phones. Cell phones or cordless phones are safe to use, though. Lightning can enter a building through wires, and then travel through electrical and phone systems.

Avoid plumbing. Pipes that extend outside of a safe building can be struck by lightning and conduct it through plumbing. 

While you may never be a lottery jackpot winner, the odds that you experience a close encounter with lightning are entirely up to you. So make your own luck.
