On August 29, 2019, the NWS follow-on enterprise EMWIN (eEMWIN) services were placed into operations
following the release of a public notification issued on August 29, 2019, via Service Change Notice:
https://www.weather.gov/media/notification/scn19-53emwin_goesaab.pdf

-eEMWIN satellite broadcast service on the NESDIS GOES-East and GOES-West HRIT/EMWIN Broadcast

NWS will provide more than 90 days of parallel operations of the legacy EMWIN services and the
updated eEMWIN services before terminating the legacy EMWIN services on December 2, 2019. This
