The NOAA Wallops Command & Data Acquisition Station (WCDAS), which 
provides the EMWIN data uplink service to the GOES-14 and 15 
satellites, will undergo a planned 48 to 60 hour facility power 
outage commencing 1200 UTC, April 3, 2018.  

Date/Time of Initial Impact:  April 3, 2018  1200 UTC

** NOTE: The EMWIN satellite broadcast outage may commence any time 
         after April 2, 2018  2045 UTC **

Date/Time of Expected End:  April 5, 2018  2359 UTC

Length of Outage: 48 to 60 Hours

The outage is required to perform maintenance and repairs on the 
station's electrical power system. The power outage can be 
expected to last as long as three days, although the goal is to 
complete the work within two days.  

It is likely there will be an outage of the 1692.7 MHz Emergency 
Managers Weather Information Network (EMWIN) broadcast for the 
duration that WCDAS is down for both GOES-14 and 15. If there is 
an outage, users are asked to utilize GOES-15’s LRIT broadcast,
