During a winter weather event, Charlotte Regional Skywarn usually activates an informal net. During these nets, normal operation of the repeater is allowed and a NCO is usually monitoring for reports. At the top of each hour we will usually break in and ask for stations with snowfall accumulation amounts to make reports to the NCO.
Here are the guidelines from the NWS in Greer, SC on how to measure snowfall, and report it VIA twitter. We also take these reports and pass them to the NWS VIA NWSChat.
