June 18, 2026 · The Clime Team

Thunderstorms are powerful natural events that can pose significant risks, including lightning strikes, strong winds, hail, and flash floods. Understanding and implementing safety measures can greatly reduce the dangers associated with these storms.

What Are Thunderstorms and Their Risks?

A thunderstorm is a rain-bearing cloud system that produces lightning and thunder. While they can occur at any time, thunderstorms are most common in the spring and summer months. The primary hazards associated with thunderstorms include:

Lightning Strikes: Lightning can cause fires, power outages, and injuries.
Strong Winds: High winds can uproot trees, damage buildings, and create flying debris.
Hail: Hailstones can damage crops, vehicles, roofs, and windows.
Flash Floods: Heavy rainfall can lead to rapid flooding, especially in low-lying areas.

How Can I Protect Myself During a Thunderstorm?

Indoors:

Stay Inside: Remain indoors during a thunderstorm.
Avoid Water: Do not bathe, shower, wash dishes, or have any other contact with water during a thunderstorm because lightning can travel through a building’s plumbing. (cdc.gov)
Avoid Electronics: Do not use anything connected to an electrical outlet, such as computers, laptops, game systems, washers, dryers, or stoves. (cdc.gov)
Stay Away from Windows and Doors: Stay away from windows and doors, and stay off porches. (cdc.gov)
Use Cordless Phones: Corded phones are NOT safe to use during a thunderstorm. However, cordless or cellular phones are safe to use during a storm. (cdc.gov)

Outdoors:

Seek Shelter: When you hear thunder, seek shelter inside a sturdy building or a hard-top vehicle. (cdc.gov)
Avoid Water: Get out of boats and away from water. (cdc.gov)
Stay Away from Trees: Do not shelter under trees. (cdc.gov)
Avoid Open Areas: Stay away from open spaces such as golf courses, parks, playgrounds, ponds, lakes, swimming pools, and beaches. (cdc.gov)
Avoid Electrical Appliances: Avoid using electrical appliances during a thunderstorm. Cell phones, laptops, and devices that aren’t plugged in are OK. Don’t use a phone with a cord. (tdi.texas.gov)

What Should I Do If Someone Is Struck by Lightning?

If someone is struck by lightning, call 9-1-1 immediately. Give first aid, including CPR, if the victim is not breathing. You can touch the victim; the lightning’s charge will be gone. Move the victim someplace safe; lightning can strike the same place twice. (tdi.texas.gov)

How Can I Stay Informed About Thunderstorms?

Monitor Weather Alerts: Pay attention to weather alerts and local information. Postpone outdoor activities if the forecast calls for thunderstorms. (redcross.org)
Use Reliable Sources: Use battery-operated devices such as flashlights to listen to weather updates. (tdi.texas.gov)

What Are Some Common Myths About Thunderstorm Safety?

Myth: Lightning never strikes the same place twice.
Fact: Lightning can strike the same place multiple times, especially if it's a tall, isolated object.
Myth: Rubber tires protect you from lightning while in a car.
Fact: While rubber tires may provide some insulation, the metal frame of the car conducts electricity, protecting you from lightning.
Myth: You can outrun a thunderstorm in a vehicle.
Fact: Thunderstorms can move quickly, and it's unsafe to try to outrun them.

How Can I Prepare My Home for Thunderstorms?

Secure Outdoor Items: Bring in or secure outdoor furniture, decorations, and anything else that could become a projectile.
Check Windows and Doors: Ensure all windows and doors are closed and secure.
Install Surge Protectors: Use surge protectors to safeguard electronic devices from power surges caused by lightning.

What Are the Signs That a Thunderstorm Is Approaching?

Darkening Skies: The sky may turn dark or greenish.
Increased Wind: Sudden gusts of wind can precede a storm.
Distant Thunder: Hearing thunder from a distance indicates a storm is nearby.

How Can I Educate My Family About Thunderstorm Safety?

Discuss Safety Plans: Talk about where to go and what to do during a thunderstorm.
Practice Drills: Conduct family drills to ensure everyone knows the safety procedures.
Stay Updated: Keep informed about weather forecasts and alerts.

By understanding and following these safety guidelines, you can significantly reduce the risks associated with thunderstorms and protect yourself and your loved ones.
