MEMORANDUM FOR:   Distribution E

FROM:             John H. Ward
                 Chief, Production Management Branch

SUBJECT:          Changes to the NWS Production Suite


    The grid configuration of the GFDL hurricane model will be
modified on Tuesday, 21 May 2002.  Under the new two-nest grid
configuration, the region covered by 1/6 degree resolution will
be increased from a 5 degree domain to 11 degrees.  This area
corresponds to the region previously covered by the 1/3 degree
resolution middle grid.  In addition, the resolution of the outer
most grid will be changed from 1 degree to 1/2 degree.  Details
of the new model configuration can be found at:

    New disks will be added to the NFS and the GPFS on both ASP
and BSP during the months of May and June.  While this work is
occurring, users should be aware that the development machine may
be unavailable.  In addition, there will be lengthy periods when
production will be running on the development machine.  The
complete schedule for these upgrades can be found at:

available, links will be added on the change summary page.
