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 .

I understand . They think a tornado might come .
neutral
assistant
Yes . People should look out , because maybe there will be tornadoes coming.So it's called a " watch . "

And the second stage is called a " tornado warning " .
neutral
assistant
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 .

It's scary .
neutral
assistant
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 .

What do you mean " a loud train " ?
neutral
assistant
That is what tornadoes sound like . They sound like trains . They're very loud .
neutral
user
But if you hear them coming , isn't it already too late ?
neutral
assistant
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 .

Have you seen a lot of them ?
neutral
assistant
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 .

Did it hit their house ?
neutral
assistant
No , it didn't . But they are glad I called them .
neutral
user
What were they doing when you called ?
neutral
assistant
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 .
neutral
user
That's terrible . Do many people die in tornadoes ?
