What is SKYWARN?


In most years, thunderstorms, tornadoes and lightning cause hundreds of injuries and deaths and billions in property and crop damages. To obtain critical weather information, the National Weather Service (NWS) established SKYWARN® with partner organizations. SKYWARN® is a volunteer program with between 350,000 and 400,000 trained severe weather spotters. These volunteers help keep their local communities safe by providing timely and accurate reports of severe weather to the National Weather Service. Although SKYWARN® spotters provide essential information for all types of weather hazards, the focus is reporting on severe local thunderstorms. In an average year, the United States experiences more than 10,000 severe thunderstorms, 5,000 floods and more than 1,000 tornadoes.

Since the program started in the 1970s, the information provided by SKYWARN® spotters, coupled with Doppler radar technology, improved satellite and other data, has enabled NWS to issue more timely and accurate warnings for tornadoes, severe thunderstorms and flash floods. SKYWARN® storm spotters form the nation's first line of defense against severe weather. There can be no finer reward than to know that your efforts have given your family and neighbors the precious gift of time--minutes that can help save lives.


Frequently Asked Questions

How do I become a member of SKYWARN?

SKYWARN is not really something to be a member of. It’s the concept of using volunteer storm spotters to provide critical information to local communities and to the NWS, and that’s what has driven the storm spotter program since it began decades ago. It's a great idea to contact your local emergency manager to find out what formal spotter networks are in place near you and how you can get involved. We are also happy to provide help and guidance.

What is my spotter ID number? Do I get an ID card?

NWS Columbia does not issue ID cards or spotter ID numbers. After you complete training, you can register with us. You'll then be added to our roster of qualified SKYWARN Spotters.

Do I need an amateur radio license to be a storm spotter?

You don’t have to be an amateur radio operator to make a severe weather report, but many spotter networks are made up of dedicated amateur radio operators who use radio to coordinate their local network and to relay reports to the NWS. If you’re interested in learning more about amateur radio, visit this site. The only requirement for becoming a spotter is a desire to complete training, and to be a volunteer that can make a life-saving difference.

Do I need to be a storm chaser to be involved in SKYWARN?

Absolutely not! We do not ask our SKYWARN Spotters to chase tornadoes or severe weather. The idea behind the program is to report severe weather from where you are...whether at home, school, work or play. For safety reasons we do not train or ask our spotters to chase any severe weather, and to only send reports when it is safe to do so.

NWS Columbia's County Warning Area (CWA) & Amateur Radio Network


NWS Columbia utilizes the 2-Meter amateur radio network across Central SC and the CSRA to obtain severe weather reports. When a significant severe weather outbreak is anticipated, NWS meteorologists will ask for Net Control Stations to SKYWARN radio nets in areas threatened by severe weather. We may also call Amateur Radio Operators into our office to collect reports from the area nets, or establish one as well. The Call Sign for the NWS Columbia Office during an organized radio net is WX4CAE. When calling net control, simply call Columbia SKYWARN. It is not the intent of the net to provide the latest conditions and forecasts. The purpose of the net is to receive reports, not give them out. During an active weather net, the operator may monitor the following repeaters:

  • 147.210 MHz - Little Mountain Repeater
  • 145.490 MHz - Trenton Repeater
  • 147.105 MHz - Bishopville Repeater
  • 147.015 MHz - Sumter Repeater
  • 145.450 MHz - Savannah River Site (CSRA Backup)
