How to Prepare for a Thunderstorm
Weather Safety • Practical Guide • 6 minute read
Thunderstorms feel ordinary until one arrives at the wrong moment: you are on the road, at a cricket ground, on a rooftop taking in the washing, or halfway through a hike. They can turn a calm afternoon into a hazard within minutes, bringing lightning, damaging wind, hail and flooding. The good news is that most thunderstorm injuries are preventable. A little preparation, done before the first cloud darkens, makes a big difference.
Why Thunderstorms Are Dangerous
A thunderstorm is a storm that produces lightning, and thunder is simply the sound that lightning makes. Each storm can bring several hazards at the same time:
- Lightning: it can strike up to many kilometres away from the storm’s rain, sometimes even when the sky above you looks clear.
- Strong winds: sudden gusts can snap branches, topple billboards and lift loose roofing.
- Heavy rain and flash floods: streets, underpasses and low-lying areas can fill with water very fast.
- Hail: it can damage vehicles, crops, solar panels and skylights.
- Power cuts: falling lines and surges can leave a neighbourhood without electricity for hours.
Know When a Storm Is Coming
The earlier you know, the more time you have. Make forecast checking part of your routine, especially during pre-monsoon and monsoon weeks when afternoon storms are common in much of Pakistan.
- Look at the hourly forecast and the rain and cloud maps before leaving home.
- Pay attention to words like “thunderstorm”, “severe” and “warning” in the forecast.
- Follow alerts from your national or local meteorological authority, and treat them as more important than any general app.
- Watch the sky. Towering, dark clouds, a sudden drop in temperature, a gusty wind and a heavy, humid feeling are classic warning signs.
Prepare Your Home Before the Storm
- Secure loose items. Bring in chairs, pots, bicycles, washing and anything that can become a flying object. Tie down or weigh down items that cannot be moved.
- Check windows and doors. Close them firmly. Move furniture away from large glass panes.
- Trim risky branches. Dead or overhanging branches near your house, car parking or power lines should be dealt with during dry weather, not in a storm.
- Clear drains and gutters. Blocked water paths cause pooling and leaks.
- Charge your phone and power bank while electricity is still available.
- Protect electronics. Use a good surge protector, and unplug sensitive devices such as computers, televisions and routers when a storm is close.
Build a Simple Emergency Kit
You do not need anything fancy. Keep these items in one place that everyone in the house can find, even in the dark:
| Item | Why you need it |
|---|---|
| Torch and spare batteries | Safer than candles during power cuts |
| Power bank and charging cable | Keeps your phone alive for calls and updates |
| Drinking water and dry snacks | Useful if you are stuck at home for hours |
| First-aid kit and regular medicines | For minor injuries and daily health needs |
| Battery or hand-crank radio | Receives updates when networks fail |
| Important papers in a waterproof bag | Protects ID and documents from leaks |
| Emergency phone numbers on paper | Works even if your phone is dead |
What to Do When Thunder Starts
A well-known safety rule says: when thunder roars, go indoors. If you can hear thunder, you are close enough to be struck. Do not wait for rain.
- Go inside a solid building or a hard-topped vehicle with the windows closed. Open shelters such as picnic huts, tents, sheds and bus stops do not protect you from lightning.
- Stay away from windows and doors. Pick an inner room if possible.
- Avoid plumbing. Do not shower, wash dishes or touch taps. Lightning can travel through metal pipes and water.
- Avoid corded devices and wired equipment. Skip landline phones, plugged-in appliances and anything connected to the mains. Phones on battery power are fine.
- Do not lean on concrete walls or lie on concrete floors, as they may contain metal reinforcement that can conduct electricity.
If You Are Caught Outdoors
Being outside during a storm is the highest-risk situation, so act early and decisively.
- Head to a building or a closed vehicle as fast as you safely can. This is always the best choice.
- Avoid tall, isolated objects like lone trees, poles, flagpoles and towers. Sheltering under a tree is one of the most common causes of lightning injuries.
- Get off hills, ridges and open fields. Move to lower ground, but away from areas that may flood.
- Stay out of water. Leave lakes, rivers, pools and the sea immediately.
- Put down metal objects such as umbrellas with metal tips, fishing rods and sports equipment, and move away from fences and metal structures.
- Spread out in a group, so a single strike does not injure everyone.
- As a last resort, if you feel your hair stand on end and no shelter is available, crouch low on the balls of your feet with your head tucked in and your hands over your ears. This reduces risk slightly but is not a substitute for real shelter.
Driving in a Thunderstorm
A car with a solid metal roof is a reasonably safe place from lightning, but driving brings other risks.
- Slow down, switch on your headlights and keep a longer distance from the car ahead.
- If rain is too heavy to see, pull over somewhere safe, away from trees, billboards and power lines, and wait.
- Never drive through flooded roads. Just thirty centimetres of moving water can sweep a small car away, and the depth is hard to judge. Turn around and choose another route.
- If a power line lands on your vehicle, stay inside and call emergency services. Do not step out.
After the Storm Passes
- Wait at least 30 minutes after the last thunder before going outside.
- Stay away from fallen power lines and anything touching them. Report them to the electricity provider.
- Be careful around damaged trees, walls and roofs, which may collapse.
- Avoid floodwater, which can hide open drains and carry contamination.
- Check on neighbours, especially older people, children and anyone living alone.
- Throw away any food that has been warm for hours after a long power cut.
Helping Someone Struck by Lightning
People who are struck do not carry an electric charge, so it is safe to touch them. Call local emergency services at once, for example Rescue 1122 where available. If the person is not breathing, begin CPR if you know how and continue until help arrives. Move them to shelter only if the storm is still active and it is safe to do so.
Frequently Asked Questions
Can lightning strike the same place twice?
Yes. Tall structures can be struck many times, sometimes several times in one storm.
Is it safe to use a mobile phone during a storm?
Yes, a cordless or mobile phone is fine indoors. Avoid phones that are plugged into a charger or a wired landline.
Can lightning strike when it is not raining?
Yes. It can reach several kilometres ahead of or behind the rain, which is why hearing thunder is your signal to go inside.
Is it safe to stay in a car?
A hard-topped car is a good shelter from lightning, but convertibles, motorbikes and rickshaws with open sides are not.
Final Thoughts
Thunderstorms cannot be stopped, but their dangers can be managed. Check the forecast, tidy up your surroundings, keep a small emergency kit ready and follow the 30-30 rule. When thunder sounds, treat it as a clear instruction to move indoors. The few minutes you spend preparing now can protect you, your family and your home when the sky turns dark.
