When you are outside, there is an easy way to tell if a storm cloud is approaching. There are three signs that storm clouds are approaching. “A black cloud is approaching”, “I hear a rumbling thunder” and “Suddenly a cold wind blows.” If you feel any of these changes, you should evacuate to a safe location immediately, as heavy rain and thunder may soon occur.
When a storm approaches, the best place to evacuate is in a nearby solid building or car. Taking shelter from the rain under a tree is dangerous because lightning strikes the tree can jump people. If there is nowhere to evacuate, squat with your feet together and your head down and cover your ears with both hands.
