SUBJECT: Changes to the NWS Production Suite 1. Due to the declaration of critical weather Monday throughWednesday of this week (02-04 August 2004), several of the changes advertised in last weeks JIF memo were either implemented on Thursday of this week (05 August 2004) or moved to next week. The items moved to next week are highlighted in the synopsis section below.
2. Installation of the CCS Phase II system has begun. Thetransition of NCEP operations to the Phase II system is expected to begin in mid September 2004, with the system expected to become
operational on or about 18 January 2005. Based on the currentinstallation schedule, the moratorium on changes to the Production Suite is expected to begin on or about 1 October and end in January 2005. Changes required to correct operational failures will continue to be made during the moratorium.
Major implementations scheduled prior to the moratorium are:
Aug 17 - SREF diversity upgrade
Aug 24 - Coupled-Climate Forecast System (CFS)
Sept 21 - Hi Res Window WRF ensemble
3. The transition in the file naming convention for the Global
Forecast System (GFS) has begun. On 14 June 2004, a duplicate file structure was
established on both the TOC and NCEP FTP servers. All file structures containing
AVN now have a duplicate link containing GFS. These duplicate file structures will
remain in place for six months. On approximately 18 January 2005, all file
structures containing AVN will be eliminated. Additional details about this
transition can be found at the following web site:

4. NCEP Central Operations is implementing a new DNS solution for World Weather
Building (WWB), Camp Springs, MD. The deployment of the new DNS solution is
scheduled to commence 23 August 2004. A component of the DNS solution is the
retirement of the "wwb.noaa.gov" and "fb4.noaa.gov" DNS domains. The domain
"ncep.noaa.gov" is and will be supported in lieu of the "fb4" and "wwb" domains.
Scripts that access NCEP hostnames using the "wwb.noaa.gov" should have been changed to "ncep.noaa.gov" by 1 August 2004. For example, if accessing "ftpprd.wwb.noaa.gov", change to "ftpprd.ncep.noaa.gov". This will allow time to address problems before the deployment of the new DNS system. For internal NCEP users, a separate communications will provide further instructions. If there are any questions or concerns, please
email ncep.helpdesk@xxxxxxxx and copy Luis.Cano@xxxxxxxx.
