...Software Upgrade Will Impact NOAA Weather Radio This Week...

The National Weather Service in Green Bay, Wisconsin will be
conducting a required, scheduled update to their Advanced Weather
Interactive Processing System (AWIPS) system from around 8 AM CDT
Tuesday, May 13 through approximately the evening of Thursday May
15, 2025. 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, forecast operations will be conducted
by our service back-up office in Milwaukee, Wisconsin 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:

NOAA Weather Transmitters: All NOAA Weather Radio transmitters
maintained by NWS Green Bay will be off air through 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=GRB.

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/grb/.

Local graphical forecast maps that are hosted in numerous places on
www.weather.gov/grb will not be updated. This includes all maps on
the Graphical Hazardous Weather Outlook page
(https://www.weather.gov/erh/ghwo?wfo=grb).

The KGRB radar will remain operational and its products will
continue to be distributed as normal. The NWS Green Bay 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.

Please contact us at NWS.GreenBay@noaa.gov with any questions.
