Weather Spotters
Latest News: - A recorded version of our 2020 Spotter Talk is available! |
Storm spotters are volunteers who help their community and NOAA's National Weather Service by keeping an "eye on the sky" during severe weather. Our spotters contact the NWS via phone, amateur radio, or the internet, keeping our forecast staff updated with the latest weather information from their location. Anyone over the age of 15 years old can become a spotter. If you would like to become a severe weather spotter for northeast or north-central Wisconsin, you must either attend training presented by NWS Green Bay or take the three online courses in the "Training Online" section below. To remain a spotter in good standing, you must either attend a refresher course or retake the online courses (see "Training Online" section below) every 2-4 years.

Amateur Radio Operations at NWS Green Bay - WX9GRB
Amateur radio spotters provide valuable weather reports to the NWS Green Bay office during severe weather. Several volunteer net controllers, led by Christian Reynolds (KC0ARF), staff the amateur radio desk at the NWS Green Bay office--WX9GRB (above, left)--and stay in contact with spotters across northeast and north-central Wisconsin. The 80 ft tower (above, right) is home to the antennas.
