Understanding Weather Watches, Warnings, and Advisories

Weather-related events can pose significant risks to life and property. In the United States, the National Weather Service (NWS) issues specific alerts to inform the public about these hazards: Watches, Warnings, and Advisories. Understanding these terms is crucial for effective preparedness and response.

What Is a Weather Watch?

A Watch is issued when the risk of a hazardous weather or hydrologic event has increased significantly, but its occurrence, location, or timing is still uncertain. It serves as a preliminary notification, allowing individuals to set plans in motion and stay alert for further updates. For example, a Severe Thunderstorm Watch indicates that conditions are favorable for severe thunderstorms to develop. (weather.gov)

What Is a Weather Warning?

A Warning is issued when a hazardous event is occurring, imminent, or likely. Warnings advise of a threat to life or property, urging immediate action. For instance, a Severe Thunderstorm Warning means that severe thunderstorms are imminent or occurring, and people should take protective measures. (weather.gov)

What Is a Weather Advisory?

An Advisory is issued when a hazardous event is occurring, imminent, or likely, but conditions are less serious than those requiring a warning. Advisories are intended to inform the public of significant inconveniences that, if caution is not exercised, could lead to situations that may threaten life or property. For example, a Wind Advisory is issued when sustained winds of 31 to 39 mph are expected for an hour or more, or wind gusts of 46 to 57 mph are anticipated. (weather.gov)

How Are Watches, Warnings, and Advisories Issued?

The NWS issues these alerts based on specific criteria:

• Watches: Issued when there is a 50% confidence that warning criteria will be met, generally within 36-48 hours.

• Warnings and Advisories: Issued when there is an 80% confidence in the event's occurrence, typically within 24-36 hours. (weather.gov)
