...NOAA WEATHER RADIO TRANSMITTER NEAR MINOT TO EXPERIENCE
NUMEROUS POWER INTERRUPTIONS INTO LATE NOVEMBER...

Power to the transmitter will be turned off from time to time
while a new communications tower is being constructed. The
tower is expected to be finished by November 28th.

If the power is off when a weather warning or weekly test is
sent it would not pass through the transmitter site. Be sure
to have alternate ways to receive emergency messages, like
the National Weather Service web page at www.weather.gov/bis,
through NWS social media, or through other local media outlets.
