What is the difference between a tornado watch and a tornado warning?

Here's the difference between a tornado watch and a tornado warning:

A Tornado Watch means that conditions are favorable for tornadoes to develop in a specific area. It indicates that atmospheric instability and wind shear are present, increasing the risk of severe thunderstorms that could produce tornadoes. A watch covers a larger geographical area and a longer period of time (usually several hours). During a tornado watch, you should:

• Stay informed by monitoring weather updates from reliable sources (e.g., NOAA Weather Radio, TV, internet).
• Be prepared to take action if a warning is issued.
• Review your safety plan.

A Tornado Warning means that a tornado has been sighted or indicated by weather radar and is imminent. It signifies an immediate threat to life and property. A warning covers a smaller geographical area and a shorter period of time than a watch. During a tornado warning, you should:

• Seek shelter immediately in a basement, storm cellar, or interior room on the lowest floor of a sturdy building.
• If you are in a vehicle or outdoors, find the nearest sturdy shelter. As a last resort, lie flat in a ditch or low-lying area and cover your head.
