Thunderstorms are more than just loud and flashy—they can be deadly. Lightning strikes, flash floods, and high winds cause thousands of injuries and deaths every year. Yet, many people still make dangerous mistakes when storms roll in.
Here are 10 things you should NEVER do during a thunderstorm—and what you should do instead to stay safe.
1. Stand Under a Tree for Shelter
Many people instinctively run under trees when it starts raining. Bad idea.
Why it’s dangerous: Trees are lightning magnets. If lightning strikes, the current can jump to you, or falling branches can crush you.
Instead, seek shelter indoors or in a hard-top car. If no shelter is available, crouch low in an open area away from trees. You’ll get wet, but at least you won’t get fried or crushed.
2. Use a Landline Phone
If you are one of the dozens of people who still have a corded landline phone, using it during a thunderstorm is a major risk.
Why it’s dangerous: Lightning can travel through phone lines, electrocuting anyone holding the receiver.
Instead, use a cell phone or cordless phone, but avoid charging them during the storm.
3. Take a Shower or Use Plumbing
Why it’s dangerous: If lightning strikes your home, the electric current can travel through plumbing, electrocuting anyone using the shower, sink, or even flushing a toilet.
Instead, try to wait until the storm passes before using water. If nature is calling, at least try to wait for a quiet moment.
4. Stay in an Open Field
Being the tallest object in an open field makes you an easy target for lightning.
Why it’s dangerous: Lightning tends to strike the highest point—if that’s you, you could be in serious trouble.
Instead, crouch low with your feet together and minimize contact with the ground. Do NOT lie down!
5. Drive Through Flooded Roads
Flash floods can turn roads into rivers in minutes.
Why it’s dangerous: Just six inches of water can knock you off your feet, and 12 inches can float a car. Two feet of water can sweep away even large vehicles.
Instead, remember: “Turn around, don’t drown.” Find another route or wait for water to recede.
6. Play Outdoor Sports or Swim
If you can hear thunder, you’re already in danger.
Why it’s dangerous: Lightning can strike before rain even starts. Water conducts electricity, so swimming during a storm is extremely deadly.
Instead, get indoors immediately. Wait at least 30 minutes after the last thunderclap before resuming outdoor activities.
7. Stand Near Windows or Glass Doors
Watching a storm up close can be fascinating, but lightning can shatter glass.
Why it’s dangerous: High winds can blow debris into windows, and lightning can travel through metal window frames.
Instead, stay away from windows and doors. Sit near the center of the house until the storm passes.
8. Lie Down on the Ground During a Storm
If you’re caught outside, lying down might seem safer—but it’s not.
Why it’s dangerous: Lightning spreads across the ground when it strikes. Lying down increases your contact with the ground, making you more likely to be electrocuted.
Instead, crouch low with feet together and minimize contact with the ground.
9. Use Electronics That Are Plugged In
If lightning strikes nearby power lines, it can send a surge through electrical outlets.
Why it’s dangerous: Electronics plugged into wall outlets can be fried, and anyone using them could be electrocuted.
Instead, unplug electronics before a storm arrives. Use battery-powered devices instead.
10. Ignore the 30/30 Lightning Rule
Some people think as long as it’s not raining, they’re safe.
Why it’s dangerous: Lightning can strike miles away from a storm. The 30/30 rule helps gauge when it’s safe to go outside.
The 30/30 Rule:
- If you hear thunder within 30 seconds of seeing lightning, seek shelter immediately.
- Wait at least 30 minutes after the last thunderclap before going back outside.
Thunderstorms can be deadly, but smart choices save lives. Avoid these common but dangerous mistakes, and always respect the power of nature. Have you ever had a close call with lightning? Share your story in the comments!
