Glossary Of NWS Related Terms

Hello everyone!

In an effort to break down the long list of terms you may see in my discussions or in the discussions of others, here is a list of the terms you will find usedwhen talking about the National Weather Service. I hope to add the complete list of Watches/Warnings in here as well at some point.


AFD: Area Forecast Discussion. A product issued twice a day by the National Weather Service that gives a technical summary of the weather to come. Useful for weather geeks, not so much for everyone else.

FROPA: Frontal Passage. Used as shorthand especially by the NWS to convey the passage of any type of front.

NWS: National Weather Service. The official issuer of watches/warnings/advisories etc. ALWAYS consult with the NWS forecast to make important decisions and to get the best possible forecast.

WFO: Warning Forecast Office. Local NWS subsidiaries that provide forecasts for specific locations as well as issue warnings for their CWA (County warning area)
