Lightning is one of the most powerful weather forces to hit Earth. These huge electricity that strike (撞击;击打) during storms can cause destruction and death. Lightning can heat the air around it to temperatures five times hotter than the surface of the sun.
Lightning is very common. It is estimated (估计) that every second, about 100 lightning strikes hit the surface of the Earth.
Lightning can be deadly. It is difficult to keep exact records on how many people die from lightning each year throughout the world. Some experts estimate that about 2, 000 people die each year from lightning. Others say the number could be as high as 24, 000.
So how to stay safe during a lightning storm is important. Experts at the weather gov (政府) website, give tips on staying safe if lightning comes your way.
Outdoor lightning storm
If you are outside, you should take cover, which means finding a safe shelter for protection. During a lightning storm, no place outside is safe. If you hear thunder, lightning is close enough to strike you. Most lightning victims (受害者) are in open areas or near a tree.
Nowhere to hide
If you are outside during a lightning storm and there is no safe shelter, these actions may reduce your risk:
●Immediately leave high land areas, such as hills or mountains.
●Never lie flat on the ground.
●Never shelter under a tree sitting in the open.
●Immediately get out of any bodies of water and stay away from those areas.
●Stay away from objects that can conduct electricity, such as wire fences, tall buildings, power lines or windmills.
Indoor lightning storm
Stay off wired phones, computers and other equipment that can put you in direct contact with electricity.
●Avoid any areas with running water.
●Remain indoors but stay away from windows and doors.
●Do not lie on concrete (混凝土) floors or touch concrete walls.

My name is Lenny and I’m 16 years old. I grew up in New Orleans (新奥尔良). When Hurricane (飓风) Katrina hit, I was only 12. I was at my cousin’s house for the weekend and we were watching Saturday TV in his room. We didn’t know anything about it and then suddenly all the electricity went out. We looked out of the window and it was raining and it was really windy. The trees were bent over. There was so much water in the streets. We opened the bedroom door and saw that there was water everywhere. So we tried to climb onto the roof (屋顶). There were lots of people on roofs around our neighborhood.
When the Hurricane Katrina hit, 80% of the city was under water, so it was very difficult for people to leave. There were so many people that the city officials (官员) didn’t really know what to do with them. At last, a helicopter (直升飞机) picked us up and took us to another city.
