A tornado warning is worse. It means that a tornado has been detected or the threat of one is imminent. A tornado watch means the overall conditions are favorable to form in a general area.
Watches Versus Warnings. Many people confuse the meaning of a tornado watch and tornado warning when they are issued by the National Weather Service. Here's the difference: Watch: Tornadoes are possible in your area. Remain alert for approaching storms. Warning: A tornado has been sighted or indicated by weather radar. If a tornado warning is issued for your area and the sky becomes threatening, move to a pre-designated place of safety.
