...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.
