Important Note About Spotter Numbers:


NWS Greenville-Spartanburg has discontinued the issuance and use of spotter ID numbers. Spotters who wish to obtain some sort of identification number are encouraged to consider becoming a CoCoRaHS observer to supplement their SKYWARN service.


What is the SKYWARNTM Spotter Program?


SKYWARN is the National Weather Service (NWS) program comprised of trained volunteer weather spotters. Storm spotters come from many walks of life, including fire fighters, law enforcement, amateur radio operators, and the general public. SKYWARN spotters coordinate with local emergency management officials and send reports of weather based phenomena to the NWS. Skywarn spotter training is FREEopen to any member of the public, and sometimes based on location spacing, may require registration.

Storm spotters not only serve the community, but they provide important information to warning forecasters who make critical warning decisions. SKYWARN storm spotters play a critical role of giving the NWS vital ground truth data, which helps the NWS perform our primary mission, to save lives and property.
