The Sullivan Committee itself does not "own" any repeater equipment, but through the generous commitments of local repeater organizations, we have permission to use several machines in Sullivan's Coverage Warning Area. It is the cooperation of many groups that establishes the success of this program -- nobody can do it alone.


Backbone Net Description





Link to Backbone Net Description

Only a few special operators are authorized to be on the Backbone Net during a formal Severe Weather Net. These specially trained operators make up the Sullivan Weather Operators and the Relay Stations, who work together to handle traffic in a proper and efficient manner.

Local Net Description




Link to Local Net Descriptions

Local nets are the most important part of our system. Independent of Sullivan Committee control, these nets are comprised of local repeater systems and their associate spotters in the field.

While we do not directly control the operation of these nets, we do suggest an internal structure for them to follow. Please click the graphic on the left to find out more.


Net Interaction

How do our nets activate? What controls the process? These are very important processes to describe, as the successful allocation of resources requires us not to waste our participant's time, or the repeater airtime that independent clubs generously grant us. Please click the map on the left to follow the typical storm path from West to East. Please be warned that the page will take longer to load -- a necessary evil with all the graphics.
