3.Usually,tornadoes(龍卷風(fēng)) are more common in the spring and summer months.Knowing what to do before and during a tornado can save your life and the life of your loved ones.When you hear that you are in a tornado watch,it means that tornadoes or other kinds of dangerous weather are on the way.You need to be ready to go to a safe shelter if tornadoes do happen or if there is a warning.Listen to local radio or TV programmes for the update so that you have information to make decisions about your safety.
Tornado warnings mean that a tornado has been seen,or that radar has shown there would be a tornado.When a tornado warning is issued for your town or county,take shelter immediately.Tornado sirens(警報器) warn people who are outdoors.Do not expect to hear sirens if you are indoors.Listen to weather reports and watch TV if you are indoors.Remember to have fresh batteries for your radios and flashlights.
Plan ahead for tornado watches and warnings.Talk to your family,friends and neighbours so that you know safe places to go to get out of danger.Here are some important tips:
? Take shelter in a basement,away from any windows.
If you are in a house or building with no basement,go to the lowest floor,a small centre room such as a bathroom or closet,under the stairs,or in an inside hallway with no windows.
? If you are in a mobile home or trailer,plan ahead and get out!
It is not safe to be in a mobile home or trailer during a tornado.You need to make plans with family,friends or neighbours to go to a safer,stronger home or another building to take shelter.
? It is very risky to be in a car or truck during a tornado.
Know if there are tornado watches in the area and avoid driving into dangerous situations.Instead,take shelter in a basement or strong building.
? Have an emergency kit ready and keep it in your safe area.
A few ideas for things to have in an emergency kit would be water,a flashlight,food (like crackers,peanut butter,granola bars),a radio that uses batteries,any medications you need,and a first-aid kit.
