Warnings, often issued minutes before a tornado hits, are urgent calls to seek shelter immediately. They also differ by who issues them.

Is a tornado watch the same as a tornado warning?

A tornado watch is typically issued hours in advance by NOAA’s Storm Prediction Center (SPC). It means that conditions are ideal for a tornado to form. A warning means that either a tornado has been spotted or a radar has picked one up. If you are in an area with a tornado warning, it’s time to act immediately.

How are you warned of a tornado?

What causes a tornado watch?

The tornado watch outlines an area where an organized threat of severe thunderstorms capable of producing tornadoes are expected generally during a three- to six-hour period. If you are outdoors, develop a Weather Ready plan that includes directions to the nearest tornado shelter.

How do tornadoes form?

Tornadoes form when warm, humid air collides with cold, dry air. The denser cold air is pushed over the warm air, usually producing thunderstorms. The warm air rises through the colder air, causing an updraft. When it touches the ground, it becomes a tornado.

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

A thunderstorm watch, which can be in effect for several hours, means weather conditions exist where severe thunderstorms can easily develop. A thunderstorm warning means current storm conditions can turn worse, including heavy rain and strong winds.
