...NOAA weather radio transmitter in Chadron is down...

The KCOW radio antenna tower located in Chadron State Park that
held the NOAA Weather Radio (NWR) transmitter (KXI-20), collapsed
on Saturday, 30 November. A significant weekend winter storm
impacted the area and the combination of freezing fog, freezing
drizzle, and heavy snow together with observed winds of 50 to 60
mph, likely resulted in significant ice accretion, weight load,
and ultimately, structure failure. A blizzard warning was in
effect at the time of the tower collapse. A return to service is
unknown at this time. NWS electronic technicians and private radio
company engineers are actively assessing the situation to determine
an expedited course of action for service restoration. The
transmitter coverage area includes the northern Nebraska Panhandle
counties of Sioux, Dawes, Box Butte, and Sheridan.

The NWS Cheyenne office has worked closely with NWS Rapid City, SD
and NWS North Platte, NE to transfer NOAA weather radio warning
products and services to neighboring transmitters to increase
broadcast coverage for the affected area.

In lieu of the Chadron, NE NOAA weather radio transmitter, if you
are located in the following affected areas below, please change
your NOAA weather radio to the transmitter and frequency noted.
Please note, there may be some degraded audio quality at farther
