Functioning as the Primary Gateway to the National Weather Service Through the Collection and Distribution of Critical Weather Data and NOTAMs

The Weather Message Switching Center Replacement (WMSCR) system was the first Harris FAA program, awarded in 1988.  WMSCR was an important element of NAS Plan modernization. Located in Salt Lake City, Utah, and Atlanta, Georgia, the system collected and distributed weather data and NOTAMs to NAS users. It functioned as the primary gateway to the National Weather Service’s (NWS) National Centers for Environmental Prediction—the principal source of NWS products for the NAS.
