SUBJECT    CHANGES TO 00 AND 12 UTC NCEP RUC MODEL PRODUCT
         DELIVERY ON THE TOC FTP SERVER...EFFECTIVE
         12 UTC MARCH 2 2004

AT 12 UTC ON TUESDAY MARCH 2 2004...THE NATIONAL CENTERS FOR
ENVIRONMENTAL PREDICTION /NCEP/ WILL BE MAKING CHANGES TO WAY WE RUN THE
00 AND 12 UTC RUC MODELS.  CURRENTLY WE RUN THE ANALYSIS TWICE AT 00 AND
12 UTC.  THE FIRST RUN IS AT THE STANDARD DATA CUT-OFF PERIOD OF T+25
MINUTES.  THE SECOND RUN STARTS AT T+70 MINUTES AND IS USED TO CREATE
THE RUC FORECASTS AT 00 AND 12 UTC.  ON THE ABOVE DATE WE WILL
DISCONTINUE THE EARLY RUN WITH DATA CUT-OFF OF T+25 MINUTES.

IF YOU ARE ACCUSTOMED TO DOWNLOADING THE RUC ANALYSIS AT 00 AND 12 UTC
BASED OFF OF THIS EARLY RUN, YOU WILL NOW HAVE TO WAIT AN ADDITIONAL 40
MINUTES FOR THIS PRODUCT TO BECOME AVAILABLE.  THIS CHANGE IS BEING MADE
AS THERE IS NO LONGER A NWS REQUIREMENT TO PRODUCE AN EARLY RUC ANALYSIS
AT 00 AND 12 UTC.  THIS WILL NOT AFFECT THE TIMELINESS OF THE 00 AND 12
UTC RUC FORECASTS, NOR THE OTHER 22 RUC ANALYSIS AND FORECAST RUNS THAT
ARE MADE DAILY.

THIS AFFECTS THE DATA IN THE FOLLOWING DIRECTORIES ON THE TOC FTP
SERVER:

ftp://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/MT.ruc_CY.00/RD.{YYYYMMDD}/PT.
grid_DF.gr1

ftp://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/MT.ruc_CY.12/RD.{YYYYMMDD}/PT.
grid_DF.gr1

WHERE YYYYMMD IS THE CURRENT YEAR, MONTH, AND DATE.  THE FOLLOWING FILES
WILL NOW ONLY BE SENT ONCE PER CYCLE:
