A tornado "watch" means that conditions exist for the possible development of a tornado.

A tornado "warning" means go to cover - now.

There is a difference in the two. Where I live, we get a little too jaded over the tornado "watch" warnings. It means to stay aware.

a green sky? hail? debris ahead of the storm? -These may be signs that a tornado is coming. We have had a couple of them in our area over the years, and we have had to head for cover, but we have never heard one on its path. They say it sounds like a train.

If you are not familiar with tornadoes, you may want to Google around a bit and learn more about what to watch out for and what to do.
