Criteria for a Skywarn
An active severe weather net
WILL be brought up:
- When a severe thunderstorm or tornado warning
is in effect in Cass County.
- When there is a weather watch in Cass and
severe weather is threatening to move into the area from a surrounding
- During non-declared severe weather or at the
discretion of a club officer or trained spotter.
- At the discretion, request or order of EMA.
A Standby net CAN be brought
- During weather watch condition in Cass County
and conditions could change rapidly.
- If there is a warning in the western portion
of a surrounding county and conditions appear to be moving in our direction.
- At the discretion of EMA, an officer or
- A standby net would be for the purposes of
having spotters on standby with potential activation to an active net in the
NCS is in control and ALL communications
MUST go through NCS
Spotters report ONLY what you observe NOT
what you’ve heard no matter the source!
Confusion becomes part of the problem. We
MUST be part of the solution!
Net script may be referred to for
assistance and to keep things sounding professional.
NCS will give a situation report to include
the systems being watched, direction and speed if known, areas in the current
path. This should be given at least every 10 minutes or so.
- Rumors, inaccurate info, hearsay, and
unverifiable info can cause alarm and can cast a bad light on us as an
organization and amateur radio as a whole.
NCS call sign and notification of a weather
net in progress ex: “This is K9ABC with the Cass County Skywarn Net” WILL be
given at least every 5 minutes, preferably every 3 minutes for the purposes of
inviting more check ins and information of a net in progress. This can be
included with regular traffic.
- Spotters on the ground have no radar and
depend on NCS for info.
- Home receivers depend on us for immediate
ACCURATE information not only on the ground but also from NCS viewpoint.
- Note: Please keep the repeater active as
much as reasonably possible, a silent repeater gives no notification to someone
tuning in that there is a weather net in progress.
- Change the repeater controller to the
severe weather macro to assist in this.
