What are warnings of a tornado?

Answer:
Look for a wall/funnel cloud. A wall cloud is a dark cloud that appears very close to the earth. The color of the sky is also sometimes used to tell whether a tornado is coming or not. If there are warm drafts of wind mixing with cold ones, there is a chance a tornado could form.

I agree as well, but sudden Thunderstorms could also be a sign of a tornado.
