Subject: Amended: Addition of RAP products to NOAAPORT: 
           Effective November 19, 2012
Amended to reschedule the addition of products that had been 
delayed. The original TIN 11-19 referred to this as the addition
of Rapid Update Cycle (RUC) products to NOAAPORT, but the RUC
model has since been replaced by the Rapid Refresh model (RAP).
The WMO headers remain the same as they were for the RUC.
Effective on or around Monday, November 19, 2012, the National 
Centers for Environmental Prediction (NCEP) will begin
disseminating additional products from the Rapid Refresh (RAP)
model on NOAAPORT and the Satellite Broadcast Network (SBN).
Currently, RAP products on pressure levels on a 13km grid are 
available out to forecast hour 12 for the 0, 3, 6 ... 21 UTC
cycles, and out to 9 hours for the 1, 2, 4, 5... 22, 23 UTC
cycles. Starting with this implementation, RAP 13km output out
to forecast hour 18 will be available for all 24 cycles of the
RAP.
The products will be available with WMO headers L*D*** 
KWBG.  More details of the WMO headers can be found at:
http://www.nco.ncep.noaa.gov/pmb/changes/rap13wmo_headers.shtml These RAP products are currently made available on the NCEP 
server and can be retrieved at:
http://www.ftp.ncep.noaa.gov/data/nccf/com/rap/prod/ 
  or
ftp://ftp.ncep.noaa.gov/pub/data/nccf/com/rap/prod
in files with names rap.tXXz.awp130pgrbfYY.grib2, where XX is 
the model cycle and YY is the forecast hour.
NCEP urges all users to ensure their decoders can handle changes 
in content order, changes in the scaling factor component within
the product definition section (PDS) of the GRIB files, and
volume changes. These elements may change with future NCEP model
implementations. NCEP will make every attempt to alert users to
these changes before implementation.
