A temporary replacement (Aqua) for Frost and Snow is scheduled to be on line on Thursday, 1 June. Aqua will be the same Power5+ architecture as the CCS replacement systems.

As soon as the moratorium on changes at the NWS Telecommunications Operations Center (TOC) is lifted, NCEP will begin the transition from GRIB1 to GRIB2, by placing duplicate GRIB2 files on the TOC FTP server. Both sets of data will remain on the TOC FTP server for a minimum of 180 days to allow users to transition to the GRIB2 data sets. More information will be provided once the TOC moratorium has ended.
