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 this update, forecast and warning operations will be conducted by our back-up NWS offices to minimize any potential interruption to services. No impacts to our core forecast products and weather watches, warnings, and advisories are expected during this period. The KARX radar will remain operational, and its products will continue to be distributed as normal. NWS La Crosse will remain open and staffed throughout the update period to conduct all other functions that can be completed without AWIPS. However, the update will impact NOAA Weather Radio broadcasts originating from NWS La Crosse for the following 10 transmitters (www.weather.gov/nwr/wfo_list?WFO=ARX): * Withee, WI - KZZ77 - 162.425 MHz * Black River Falls, WI - WNG564 - 162.500 MHz * Tomah, WI - KE2XKP - 162.525 MHz * Richland Center, WI - WWG89 - 162.475 MHz * Prairie du Chien, WI - WWG86 - 162.500 MHz * Decorah, IA - KXI60 - 162.525 MHz * St. Ansgar, IA - KXI68 - 162.450 MHz * Rochester, MN - WXK41 - 162.475 MHz * Winona, MN - KGG95 - 162.425 MHz * La Crescent, MN - WXJ86 - 162.550 MHz NOAA Weather Radio broadcasts for these transmitters are expected to resume sometime on Wednesday, May 21. However, the weekly NOAA Weather Radio test, normally conducted on Wednesdays, will be postponed to Thursday, May 22 between 11 AM and noon, pending no hazardous weather. During this planned NOAA Weather Radio outage, it is important to have multiple ways to receive warning information.
