Last Revision: November 16, 2008 by Ben Holcomb (WX8BEN) with help from Ron Harger (WD8BCS)

This document is aimed at providing a guideline of procedures to follow when activating and deactivating a Skywarn net from the Lansing EOC.


Opening Procedures
  1. Call the 911 operations center at 7606 and inform them you are starting a Skywarn net and will be monitoring Tri County P.
  2. Contact Lansing Emergeny Management Chief at 483-4186.
  3. Set Kenwood 2m Radio by phone to 145.390, set Dual Band radio to 145.270 and Ingham County public service radio to TRI CO P.
  4. Check in to the National Weather Service net on 145.270. The National Weather Service callsign is WX8GRR. Just let them know you activated the Lansing Area Skywarn net and that you are standing by.
  5. Turn 145.390 repeater to Skywarn Mode. Call Ben Holcomb or Ron Harger to have the repeater toned out
  6. Prepare a "Net Control Activity Log".
  7. Prepare a "Check In Log".
  8. Prepare a "Spotter Report Log".
  9. Activate the net. Read the following bulletin on air:


Standby Net Activation Statement


"This is WC8LAN, Lansing Area Skywarn net control. The national weather service has advised (Summarize NWS Watches/Warnings and expiration). The net is now active in Standby Condition as of (Current Time) on this frequency.

While the net is in standby condition, regular Amateur Radio traffic may continue. Statements from the National Weather Service will be read periodically, and in the event a warning is issued for our area, the net will go into full activation. If this repeater should fail, the backup is 146.940 with a PL Tone of 100 Hz.

All operators checking into the net are required to check out if they need to leave the net for any reason. At the conclusion of the net, there will be a checkout roll call for those operators still shown as active.

When checking into the net, please provide your call sign slowly and phonetically, your first name and your current location.

This is WC8LAN now standing by for check-ins from trained spotters in Ingham and Clinton Counties"


Full Net Activation Statement


  • Note the time of activation the Net Control Activity Log

"This is WC8LAN Lansing Area Skywarn net control. The National Weather Service has advised (Summarize NWS Warnings and expiration). The net is now in full operation as of (Current Time) on this frequency. This is a formal and directed net and all traffic must be cleared thru net control.

The National Weather Service requests reports only of severe weather including Tornadoes, Wall Clouds, Roll Clouds, Winds greater than 30 mph, hail of any size, flooding and any severe storm related damage. Please *DO NOT* report general thunderstorm conditions such as lightning, thunder, heavy rain, tornado sirens or sky conditions.

Please use the time-event-location format for all reports. Keep all transmissions as brief as possible. This is WC8LAN."


Updates (To be read throughout the net)


"This is WC8LAN Lansing Area Skywarn with an update. (Give a summary of the RADAR including where the strongest storms are located, which general direction the storms are moving, what speed the storms are moving, what towns they are currently impacting, etc). The National Weather Service still advises (Current watches/warnings for the area and expiration times). If you have any reports of severe weather, or would like to check in or out of the net, please call net control."


Net Closing & Checkout Roll Call


"This is WC8LAN Lansing Area Skywarn Net Control. Because severe weather is no longer a threat in our area, we will now do a checkout roll call. When you are called, simply reply with your call sign and you will be checked out. If you have damage to report, let us know you have traffic. (Go down the list of remaining check ins. Log the time each operator is checked out) (Once you have reached the bottom of the list, go back to any operators with traffic.)

The Skywarn net is deactivated as of (Time).

I would like to thank everyone for their participation in the net. The frequency will now be returned to general amateur radio use. This is WC8LAN clear."


Closing Procedures
  1. Return 145.390 to normal operation mode from Skywarn mode.
  2. Call 911 center and let them know the Skywarn net is closed
  3. Check out of 145.270 liaison net with WX8GRR
  4. Place the completed Net Control Activity Log, Check In Log, and any Spotter Report logs in the wire bin directly above the Kenwood 2meter radio.
  5. Turn off radios, lights and lock door. Leave EOC as you found it.


Watch & Warning Definitions


The appropriate definition to be read accompanying National Weather Service statements.

Severe Thunderstorm Watch
A Severe Thunderstorm Watch means that conditions are favorable for Severe Thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe Thunderstorms can and occasionally do produce tornadoes.

Severe Thunderstorm Warning
A Severe Thunderstorm Warning means that Severe Thunderstorms are occurring or imminent in the warning area. A Severe Thunderstorm is defined as having one or more of the following: Winds of 58 MPH (50 knots) or higher and/or hail 3/4 of an inch in diameter or larger.

Tornado Watch
A Tornado Watch means that severe thunderstorms and tornadoes are possible in and near the watch area. It does not mean that they will occur, only that they are possible.

Tornado Warning
A Tornado Warning means that a tornado is imminent. When a tornado warning is issued for your area, seek safe shelter immediately.
