A lightning storm is caused by changes in atmospheric pressure. Thunderstorms are usually accompanied with heavy rains which lead to the occurrence of flood, strong winds, and the sound of thunder which can cause panic especially among children. As lightning always comes with thunder, this roaring sound is your danger signal: Don't be outside, when lightning could strike! Avoid contact with water, metal structures and electric applications.
Before a thunderstorm:
• Make sure that the roof gutters are fixed in place.
• Secure outdoor objects that could blow away or cause damage and keep necessary tools to repair the windows, such as wood panels and adhesive materials.
Postpone outdoor activities.
Unplug any electronic equipment well before the storm arrives.
During a thunderstorm:
• Stay inside the building or car • If you cannot go to open ground, squat low to the ground and minimize the contact by resting on the balls of your feet and putting your feet close to each other; place your hands over your ears and put your head between your knees.
• Avoid isolated tall trees or poles and high grounds.
• Avoid touching water surfaces and metal structures.
• If you are swimming get to land and find shelter immediately.
• Avoid contact with electrical equipment or cords. Unplug appliances and other electrical items such as computers and turn off air conditioners. Power surges from lightning can cause serious damage.
• Stay away from windows and doors, and stay off porches.
• If you are driving, try to safely exit the roadway and park. Stay in the vehicle and turn on the emergency flashers until the heavy rain ends. Avoid touching metal or other surfaces that conduct electricity in and outside the vehicle.
