National Weather Service Forecast Office

The Weather Forecast Office in Grand Junction, Colorado currently has 6 operational NOAA Weather Radio (NWR) transmitters that broadcast continuous weather information 24 hours a day, 7 days a week across portions of Western Colorado and Eastern Utah. In Colorado, the transmitters are located near Grand Junction, Montrose, Durango, and Glenwood Springs. In Utah, transmitters are located near Vernal and Moab. In the future, NWR will be expanding, with potential listening areas in Cortez, Craig, and Steamboat Springs.

The following is a summary for each current transmitter that includes their respective listening areas and tone alert coverage. The tone alert represents an area that will receive both the SAME alert and 1050 Hz tone when any weather warning is issued from the Weather Forecast Office in Grand Junction. This does NOT mean that other counties/areas within the listening zone will not hear the warning. It will be broadcast on NWR; however, the broadcast cycle will not be interrupted by the 2 tone alerts.

The programming schedule consists of taped messages which run continuously and are routinely revised and updated to keep western Colorado and eastern Utah listeners informed of the latest weather information affecting the region. The entire broadcast cycle typically runs from 4 to 6 minutes in length, but may vary as conditions warrant. Routine products broadcast on the radios include, but are not limited to:

1. Regional Weather Synopsis - an overview (in layman terms) of the synoptic weather patterns affecting, or expected to affect western Colorado and/or eastern Utah within the 5-day forecast period, with emphasis given to the first 48 hours. Updated 3 times a day or as needed.

2. Hazardous Weather Outlook - A daily product, issued early each morning but updated as needed. This outlook extends across a 7-day period, alerting the public to any weather, hydrologic, or no-precipitation even that has a significant chance of creating a harmful impact on people over the next week. These evens may include, but are not limited to, lightning, heavy rain, significant snowfall, very dry conditions associated with fire potential and behavior, strong winds, dense fog, bitter cold, and extremely hot temperatures. The outlook will be appended with a spotter statement, expressing whether or not weather spotters will be needed that day.

3. Local Forecasts - a 7-day forecast for sky condition, temperatures, precipitation, and wind.

4. Current Regional Weather Conditions - updated hourly, this product gives complete hourly weather observations for selected cities in western Colorado and eastern Utah on the respective radios, as well as additional regional cities across the western U.S.

5. Nowcasts - a short term forecast, concentrating on the next 1 to 3 hours, typically for a specific area or location. The forecast will incorporate current Doppler radar, satellite and automated/manned surface observations, to provide accurate and descriptive short-range outlooks.

Also, educational and promotional recordings covering various topics of interest to the general public are broadcast occasionally.

When severe weather threatens a location within the County Warning Forecast Area (CWFA), the routine broadcast cycle will be interrupted in order to activate the warning alarm. This alarm triggers specially-built weather radios to sound, letting the listener know that important live weather information will be broadcast immediately. Tests (during clear weather) of this warning alarm feature are normally conducted every Wednesday, between the hours of 11 am and noon.

Some new NOAA Weather Radio models have a SAME (Specific Area Message Encoding) alarm capability. To learn more about it:
