Person1: There is a tornado warning on . My mother just told me she heard it on the radio .
Person2: What is a tornado warning ?
Person1: It means that a tornado has been seen somewhere in the area .
Person2: Really ? In New Berlin ?
Person1: No . Not necessarily in town . But in southern Wisconsin somewhere . A tornado has been spotted . They have two stages here.This is what is called a tornado watch . That means that the weather conditions are perfect for a tornado .
Person2: I understand . They think a tornado might come .
Person1: Yes . People should look out , because maybe there will be tornadoes coming.So it's called a watch .
Person2: And the second stage is called a tornado warning .
Person1: Yes . If a tornado has been spotted , they announce a tornado warning.So if there's a tornado warning on , it means a tornado is out there somewhere .
Person2: It's scary .
Person1: Well . Tornadoes can be dangerous , it's true.If we hear something like a loud train coming , then we have to go in the basement .
Person2: What do you mean a loud train ?
Person1: That is what tornadoes sound like . They sound like trains . They're very loud .
Person2: But if you hear them coming , isn't it already too late ?
Person1: Maybe . It depends on the tornado.Some can move across the ground at 200 miles an hour.That is very fast . Others aren't so fast .
Person2: Have you seen a lot of them ?
Person1: I've only seen one in my life . I was looking out the window . It was around two miles away . It was very interesting to watch.But it was heading toward my friend's house . So I quickly called them on the phone .
Person2: Did it hit their house ?
Person1: No , it didn't . But they are glad I called them .
Person2: What were they doing when you called ?
Person1: They were all sitting in the living room watching TV.They had no idea a tornado was coming toward their house.If it had hit them , they could have all been killed .
Person2: That's terrible . Do many people die in tornadoes ?
Person1: Not so many really . But a lot of houses are destroyed sometimes .
