Removal of HTTPS access on ftpprd.noaa.com #427
Description
The used mirror ftpprd for GFS and NAM access will be removed soon:
Effective May 20, ftpprd.ncep.noaa.gov and ftp.ncep.noaa.gov will become FTP ONLY. All https traffic must switch to nomads.ncep.noaa.gov. The identical directory structure and filenames are available on nomads. Users should switch to using nomads prior to May 20.
