Understanding Weather Forecast Terminology: Watches, Warnings, and Advisories

When it comes to weather forecasts, understanding the terminology used by the National Weather Service (NWS) is crucial for personal safety and preparedness. The NWS employs a system of watches, warnings, and advisories to communicate the severity and immediacy of weather events.

What Are Watches, Warnings, and Advisories?

The NWS uses specific terms to indicate the likelihood and severity of weather events:

  • Watch: Indicates that conditions are favorable for a hazardous weather event to develop. Watches are issued when the risk of a hazardous weather or hydrologic event has increased significantly, but its occurrence, location, and/or timing is still uncertain. (weather.gov)

  • Warning: Issued when a hazardous event is occurring, imminent, or has a very high probability of occurring. Warnings advise of a threat to life or property. (weather.gov)

  • Advisory: Issued when a hazardous event is occurring, imminent, or likely. Advisories describe events that cause significant inconvenience and, if caution is not exercised, could lead to situations that may threaten life or property. (weather.gov)

Common Weather Watches, Warnings, and Advisories

The NWS issues various specific watches, warnings, and advisories based on the type of weather event:

  • Severe Thunderstorm Watch: Issued when severe thunderstorms are possible in and near the watch area. (weather.gov)

  • Severe Thunderstorm Warning: Issued when severe thunderstorms are occurring or imminent in the warning area. (weather.gov)

  • Tornado Watch: Issued when severe thunderstorms and tornadoes are possible in and near the watch area. (weather.gov)
