When severe weather threatens, trained weather spotters provide crucial ground-truth observations that help meteorologists issue more accurate and timely warnings. These volunteers serve as the eyes and ears of the National Weather Service (NWS), reporting real-time conditions that might not be visible on radar.

If you’re fascinated by weather and want to contribute to public safety, becoming a certified weather spotter through NOAA’s SKYWARN program might be perfect for you.

What is SKYWARN?

SKYWARN is a volunteer program established by the National Weather Service (NWS) in the 1960s. The program consists of trained weather spotters who provide reports of severe and hazardous weather to help meteorologists and emergency managers make life-saving warning decisions. There are over 300,000 active SKYWARN spotters across the United States, coming from all walks of life – from emergency responders and amateur radio operators to everyday weather enthusiasts.

The program’s primary goal is to save lives and property through the timely reporting of dangerous weather conditions. Spotters help identify and track severe local storms, providing information that complements data from weather radars, satellites, and other technologies.
