          System (GFS) Low-Resolution Products:
          Effective April 16, 2013

Effective Tuesday, April 16, 2013, with the 1200 Universal
Coordinated Time (UTC) cycle, the National Centers for
Environmental Prediction (NCEP) will stop producing some legacy
low-resolution gridded products from the Global Forecast System
(GFS), and stop disseminating them via NOAAPORT and the NWS ftp
server.

A Public Information Statement was issued on January 22, 2013,
requesting comments on the proposed termination of multiple
legacy GFS low-resolution products.

Based on responses received, NWS will terminate some of the
products proposed for removal. Listed below are the gridded
products available on NOAAPORT and the NWS FTP server that will
