National Warning System (NAWAS) DTRS Talkgroup/TGID 2797

[ScannerSK]

Is there anyone who takes an interest in monitoring or would like to monitor the National Warning System (NAWAS) along the front range of Northern Colorado?

Although the primary purpose for NAWAS is to warn of national and/or state emergencies most often what is heard is severe weather information.

The NAWAS talkgroup is one of my favorite things to monitor during severe weather. Reports of severe weather such as hail, flooding, funnels, tornadoes, etc. are conveyed between Colorado counties and the National Weather Service offices (Pueblo, Denver/Boulder and Goodland). In addition, severe weather watches and warnings are read aloud over the air to the various counties that have NAWAS connections.

Personally, I have heard NAWAS on the following DTRS sites:
Site 108 - 853.7750 (Lookout Mountain)
Site 112 - 853.9875 (Mead)
Site 314 - 853.6625 (North Greeley)
Site 315 - 853.8000 (Point of Rocks)
Site 361 - 853.6375 (Bald North)
Site 362 - 853.8875 (Horsetooth Mountain)

Typically, NAWAS broadcasts are only transmitted from a single tower at any given time. I believe this is due to only one station (Weld county) along the front range (Denver and areas North) that has a "radio" connection to the NAWAS system.

A daily roll call typically occurs between 10:00-10:30 a.m. each morning and 8:00-8:30 p.m. each evening. The roll call assists with determining what tower the NAWAS system is broadcasting out of when the affiliation has changed to a different tower.

Part of the challenge in monitoring NAWAS is determining what tower is currently affiliated with the NAWAS system. If anyone else is interested possibly we could collaborate our efforts.

Currently, the NAWAS system (TGID 2797) is on the Horsetooth Mountain repeater (DTRS Site 362) 853.8875 as of this evening.

NAWAS

They were quite active in the last week communicating with the NE CO LE agencies to advise of WX warnings and watches as the storms rolled through our area (Larimer - Weld). They make contact with the dispatch centers shortly after the warnings go out over the WX Radio system (162.450 in FTC).

It is good for them to have the direct contact and also good that the NAWAS is being used for WX and not any national emergencies for now.

There was some interesting monitoring on NAWAS this evening including tornado warnings north of Sterling and an unconfirmed tornado touchdown south of Dacono.

This TG has been very active this evening on Lookout. A few minutes ago I heard the roll call, there was over a dozen "stations" checking in. Does anyone know if each of the "stations" were dispatchers at various dispatch centers? Is a "station" simply someone with a phone circuit connection or radio patch to the Denver or Pueblo Weather Centers?
