Operating Procedures

There will be a DOUBLE BEEP & VOICE ANNOUNCEMENTS on the Weather Net Repeater ( 146.640) when there is an active SKYWARN WEATHER NET.

This Skywarn Weather Net is a CONTROL WEATHER NET and all stations should check into net control with their call and location (mobiles should give their current location). Check-ins should be as brief as possible as others will be trying to check in also.

What to Report:

  • Tornadoes
  • Funnel Clouds
  • Rotating Wall Clouds
  • Hail – 1″ (Quarter Size) or larger
  • Wind Gusts > 50 mph (estimated or measured)
  • Flooding
  • Any weather related damage
  • Any life threatening event
  • Do NOT report heavy rain or lighting

When Reporting:

  • Identify Yourself
  • Report event location, and be as specific as possible
  • Report the time of the observa tion

If you are monitoring the public services frequencies such as Police, Fire Departments or Sheriff’s Departments, and hear of severe weather from one of these departments please contact net control with the information.

We ask that you follow this reporting procedures so we can keep unnecessary transmissions off the net so we can get the important information we need as quickly as possible to the Weather Service.

The Net Control Operator may at times ask for weather information from counties that might be experiencing severe weather at that moment or will have a storm approaching any moment.

The Net Control Operator will be giving out information to our mobile spotters so they can get to a severe weather area as quickly as possible and as safely as possible.
