Severe thunderstorms
Experiencing a thunderstorm at a safari lodge in the bush, however, is an totally different experience. It can only be described as mind-blowing! Just as special as the stars under the African sky, so special is the bolts of lightning flashing thorough the air, lighting up the darkness.
A severe thunderstorm can cause flooding, fires, power failures and electrocution, and result in serious damage.
You can limit the dangers during a severe thunderstorm:
- Be prepared
- Take shelter as soon as you hear thunder
- Follow safety rules
- Do not rely on inadequate shelter
- Act immediately if a person is struck by lightning
- Make your environment safe and take note of the damage
Be prepared
Find out about weather alerts in effect in your region or the area where you are going. Take those alerts into account when planning your activities and travel.
Take shelter as soon as you hear thunder
To find out the distance separating you from the thunderstorm, count the seconds between the flash of lightning and the thunderclap. One second represents approximately 300 metres. For example, if five seconds elapse between the lightning and the thunder, the thunderstorm is about 1500 m (1.5 km) from where you are. You must take shelter if the thunderstorm is less than 10 km away.
Follow safety rules
Follow the safety rules wherever you may be. In the case of severe thunderstorms forecast, follow the instructions provided by the authorities.
Indoors
To stay safe when indoors, do as follows:
- Disconnect electrical devices.
- Close doors and windows securely.
- Find shelter in a room at the centre of the building, as lightning can go through outside walls, windows and doors.
- Stay away from objects that conduct electricity, such as household appliances, sinks, bathtubs, radiators and metal pipes.
- Do not use televisions or computers because they can be seriously damaged by lighting surges.
- Use battery-operated devices instead.
- Avoid using phones connected to landlines because lightning travels along electrical wiring and cords. Use wireless or cell phones instead.
- Wait about 30 minutes after the last rumble of thunder before going outside.
In a vehicle
A vehicle with a hard-topped roof (not a convertible) can serve as shelter and protect you from lightning. It is preferable not to drive during the thunderstorm and to stay far away from power lines. If a power line falls on your vehicle, remain inside the vehicle and wait for help.
Outdoors
If you are outdoors during a thunderstorm, the following advice will enable you to reduce the risks related to lightning:
- Seek shelter in the lowest area that you can find, for example a ditch.
- Squat down.
- Put your head against your knees and cover it with your arms.
- If possible, put insulating material such as a plastic bag between the ground and yourself.
- Be ready to move in the event of flash flooding.
Stay away from:
- Trees
- Telephone poles
- Power lines
- Objects that conduct electricity, such as motorcycles, lawnmowers, golf clubs or umbrellas
- Water
- Hills or any elevated places in a open area
If you are in the woods, seek shelter under a thick growth of small trees or bushes.
If you are in a boat, head for shore immediately.
Avoid barns with a sheet-metal roof that is supported by wooden beams. In addition, avoid open constructions, such as bus shelters.
Act immediately if a person is struck by lightning
If a person near you is struck by lightning, it is a medical emergency. Call 911 or go to the closest hospital centre. Be aware that:
- You can touch or transport the person to a safe location without any danger, as he or she does not carry an electrical charge.
- You can administer artificial respiration or CPR until help arrives.
- Anyone who is struck by lightning must consult a physician, even if there is no apparent injury and the person feels well.
