What is a Storm Spotter?
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. If you would like to become a severe weather spotter for northeast or north-central Wisconsin, you must attend the training presented by NWS Green Bay.
Every spring, 20-25 classes are held across northeast and north-central Wisconsin. To remain a spotter in good standing, you must attend refresher courses at least once every four years--every one or two years is preferred. The 90 minute training seminar is fast paced and filled with information.
For additional information concerning the spotter program, contact your local emergency manager or NWS Green Bay Warning Coordination Meteorologist Jeff Last (jeff.last@noaa.gov).

Amateur radio spotters provide valuable weather reports to the NWS Green Bay office during severe weather. Volunteers, lead by Andy Nemec (KB9ALN) and Christian Reynolds (KC0ARF), staff the amateur radio desk at the NWS Green Bay office (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.
