Guide to Weather Advisories, Watches, and Warnings

Have you ever heard of a watch, warning, or advisory? The National Weather Service of the United States tells the community if severe weather is on its way by using a watch, warning, or advisory. Each one has its own meaning.

Advisories tell people about weather conditions that are less severe than a watch.

A watch means there is a greater chance for severe weather, but it is still not known if, when, and where the event will take place. A watch allows people to be prepared in case a warning is given.

Warnings mean that severe weather is happening or is likely to happen. It is very important to take action when a warning is issued.
