The spotter network is usually activated whenever there is a threat of Severe Weather. This is usually preceded by the issuance of a Severe Thunderstorm Watch, Tornado Watch, Flood Watch or some other type of watch.

Skywarn will be activated under any of the following conditions:

  • Watch or Warning in Genesee County
  • Watch or Warning in NEIGHBORING Counties (Shiawasse, Livingston, Lapeer, Saginaw)
  • At the request of the National Weather Service

  2. Within a reasonable amount of time the control operator shall notify the the SKYWARN Director, Deputy Director, or Assistant Deputy Director and inform them of the activation and what part of the county is included in the watch or warning
  3. Establish a NCS.  As operators check in to the net the NCS should log their location. The NCS shall also follow the SKYWARN procedures that are listed on the website.
