Skywarn

The Yellow Thunder Amateur Radio Club, in cooperation with Sauk County ARES, is committed to providing accurate weather spotting information to the National Weather Service. Our repeater has been chosen by the National Weather Service Forecast Office at Milwaukee-Sullivan for this area and region for Skywarn activity. During any severe weather event, if you have severe weather to report, feel free to check into our net to pass your traffic. We encourage all participants to have proper Spotter Training.
