When lightning threatens, quick, informed actions can protect lives and reduce damage. Understanding what you should do in the event of lightning helps you respond confidently and safely instead of reacting in panic.
This guide outlines practical steps, emergency priorities, and common scenarios so you know exactly how to behave before, during, and after a lightning event.
| Phase | Immediate Action | Key Priority | Common Mistake to Avoid |
|---|---|---|---|
| Approaching storms | Monitor weather, move indoors if thunder is heard | Seek substantial shelter early | Waiting until rain starts to act |
| Active lightning | Stay inside, avoid windows and conductors | Minimize contact with infrastructure and devices | Using landlines or plugged electronics |
| If struck or nearby | call emergency services, administer CPR if needed, keep victim warm and stillLife preservation and rapid medical response | Moving victim unnecessarily or delaying help | |
| Post event | inspect for injuries and damage, document for insurance, avoid flooded areasSafety, recovery, and claims readiness | Underestimating internal damage or risks |
Recognizing Lightning Risk and Warning Signs
Learning to read the sky and local alerts is the first layer of protection for what you should do in the event of lightning.
Darkening clouds, distant thunder, sudden wind shifts, and official warnings are clear indicators to move to safety immediately.
Environmental Indicators to Watch For
- Towering cumulonimbus clouds or anvil-shaped tops
- Sudden drop in temperature or pressure
- Metallic tastes, buzzing sounds, or hair standing up
- Official alerts from meteorological services or apps
Immediate Shelter and Indoor Safety Steps
Getting to a safe building or enclosed vehicle is the top priority when thunder roars.
Once inside, specific behaviors reduce the risk of injury from side flashes, ground currents, and conducted electricity.
Safe Indoor Practices
- Stay away from windows, doors, and porches
- Avoid contact with plumbing, corded phones, and desktop computers
- Use cellular or cordless devices only, and unplug sensitive electronics
- Do not lie on concrete floors or lean against concrete walls
Outdoor Actions and Avoidance Strategies
If you are outside when lightning is near, moving to safe shelter quickly can make the critical difference.
When buildings are not available, smart positioning and risk awareness are essential elements of what you should do in the event of lightning.
If Caught Outside
- Seek low areas away from tall isolated objects, but avoid shallow caves or dips that may flood
- Crouch low on the balls of your feet, minimize ground contact, and keep heels together
- Stay at least 15 meters apart in groups to prevent multiple casualties from a single strike
- Leave open areas, hilltops, and bodies of water immediately; do not wait for the storm to peak
Medical Response and Aftercare
Lightning injuries require fast medical evaluation even if no obvious burns or wounds are present.
Knowing how to provide initial care and when to escalate treatment is a vital part of what you should do in the event of lightning.
Emergency Care Priorities
- Call emergency services immediately, report suspected lightning strikes
- Check breathing and pulse, begin CPR if the victim is unresponsive and not breathing
- Treat for shock, keep the victim warm, elevate legs if there are no spinal concerns
- Monitor for delayed complications such as arrhythmias, neurological changes, or hearing issues
LongTerm Preparedness and Home Protection
Planning ahead reduces vulnerability and clarifies what you should do in the event of lightning when seconds matter.
Combining shelter strategies, device safety, and family communication creates a resilient approach to severe weather.
- Install and regularly maintain lightning protection systems for structures and critical equipment
- Create a household emergency plan with clear meeting points and roles for severe weather
- Keep emergency supplies, including first aid kits and charged communication devices, accessible
- Review insurance coverage for lightning-related damage and document valuable items in advance
FAQ
Reader questions
Should I keep using my laptop or charge my phone while thunder is nearby?
Avoid using laptops, phones plugged into wall outlets, or any equipment connected to wiring or plumbing, because lightning can travel through these lines and cause injury; use only battery-powered devices and maintain distance from outlets.
Is it safe to take a shower or wash dishes during a thunderstorm?
No, avoid all contact with plumbing, including showers, bathtubs, and sinks, since water and metal pipes can conduct lightning into the home; wait until the storm passes or use only precharged cordless devices.
What should I do if someone is struck by lightning and appears unresponsive?
Call emergency services immediately, begin CPR if the victim is not breathing or has no pulse, use an AED if available, and keep the person warm and still while waiting for help to arrive.
Can lightning strike the same place twice, and how close is too close to a struck tree?
Lightning commonly strikes tall or prominent objects repeatedly, and being near a struck tree or pole poses danger from side flashes and ground current; maintain at least 15 meters of distance and move to a substantial shelter instead of staying near isolated conductors.
