The National Weather Service (NWS) and NESDIS are implementing a change to the default Mesoscale Domain Sector (MDS) locations for GOES-17. On March 5, at 1500 UTC, MDS #2 will have its default location changed to Alaska, to better serve the Alaska region of the National Weather Service. The image above shows the approximate location of the new default, centered at 56º N, 150º W (versus 35.5º N, 101.5º W). (Link).
The default location before the switch for MDS #2 is shown in this image from AWIPS. The toggle below, using SIFT, shows the approximate locations of current and future default MDS #2.
Mesoscale sectors now and in the near future can be viewed at this site.
