What is a Tornado Watch?

A tornado watch is a precautionary alert issued by the National Weather Service (NWS) when atmospheric conditions suggest that tornadoes could form. It does not mean a tornado has been spotted, but rather that the ingredients for severe weather—such as instability, wind shear, and moisture—are present.

When a tornado watch is in effect, people in the designated area should stay vigilant, monitor weather updates, and have a safety plan ready. This includes knowing where to seek shelter, such as a storm shelter, safe room, or basement.

A tornado watch typically covers multiple counties and lasts for several hours. It is different from a tornado warning, which is issued when a tornado has been sighted or detected by radar.

Understanding the difference between a tornado watch and a tornado warning is crucial for staying safe during severe weather. A watch means “be prepared,” while a warning means “take action immediately.”
