Public Information Statement
National Weather Service Bismarck ND
1231 PM CDT Fri Apr 25 2025 /1131 AM MDT Fri Apr 25 2025/

...PUBLIC INFORMATION STATEMENT...

The National Weather Service office in Bismarck, ND will be
conducting a required, scheduled update to their Advanced Weather
Interactive Processing System (AWIPS) system from approximately
7:00 am Monday, April 28 through approximately 5:00 pm Wednesday,
April 30. The NWS uses the AWIPS computer system to display and
integrate weather and water information, and to send life-saving
information, such as weather and water warnings, to the public.

During the time of the update, some forecast operations will be
conducted by our service backup back-up offices in Grand Forks,
ND and Aberdeen, SD to minimize any potential interruption to
services. No impacts to our core services of forecast products and
weather watches, warnings and advisories are expected during this
period. However, limited impacts will occur to the following
services:

All NOAA Weather Radio transmitters maintained by NWS Bismarck
will be off the air during the time of the install. A listing of
NOAA Weather Radio transmitters that will be impacted can be found
at weather.gov/nwr/wfo_list?WFO=BIS.

The KBIS radar will remain operational and its products will continue
to be distributed as normal. The NWS Bismarck office will remain
open and staffed at all hours throughout this update period to
answer public and partner phone calls, and additional functions
that can be completed while our AWIPS is upgraded.

During periods of planned or unplanned outages it is important to have
multiple ways to receive warning information. These alternative
sources include: local television/radio, weather apps on your
mobile device, such as the FEMA or Red Cross App, and at the NWS
website at weather.gov/bis/.

Local graphical forecast maps that are hosted in numerous places on
www.weather.gov/bis will not be updated. This includes all maps
on the Graphical Hazardous Weather Outlook page
(https://www.weather.gov/erh/ghwo?wfo=bis) and graphics on the
Cold Advisory For Newborn Livestock page
(https://www.weather.gov/bis/canl).

The forecast office in Bismarck, ND will remain open and staffed
throughout this period for public and partner phone calls and
additional functions that can be completed without AWIPS.
