Subject:  Two Operational Fire Weather Elements to be
          Added to the National Digital Forecast Database for
          the United States, including Alaska, Hawaii, Guam and
          Puerto Rico, Effective November 27, 2012

Effective Tuesday, November 27, 2012, at 1400 Coordinated
Universal Time (UTC), the National Digital Forecast Database
(NDFD) will add Daily Maximum and Minimum Relative Humidity (RH)
operationally to for the United States, CONUS and OCONUS,
including Alaska, Hawaii, Guam and Puerto Rico. These elements
are generated from computation of the existing hourly dew point
and hourly temperature grids.

These two fire weather elements will be in the NDFD for the valid
times shown:

- Maximum Relative Humidity (Days 1-7)
- Minimum Relative Humidity (Days 1-7)

More details regarding these elements are available in the
Product Description Document (PDD) in the online catalog of NWS
products and services.

http://products.weather.gov/

With this implementation, these forecasts will be available from
NDFD in the standard methods:

- GRidded Binary version 2 (GRIB2) files via Hypertext Transfer
  Protocol (HTTP) and File Transfer Protocol (FTP)
- eXtensible Markup Language (XML) via Simple Object Access
  Protocol (SOAP)
- Graphics via Web browser:  http://graphical.weather.gov/

Users who pull NDFD elements in GRIB2 format, either via the
internet or via the Family of Services server access service, may
need to update their procedures and scripts in order to access
these elements. The GRIB2 files are online at:

ftp://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/DF.gr2/DC.ndfd/

and

http://weather.noaa.gov/pub/SL.us008001/ST.opnl/DF.gr2/DC.ndfd/

Partners and users who use the NDFD in XML via Web service or the
online graphical NDFD images can use the same methods they
currently use to acquire these elements.

More information about accessing and using NDFD elements is
online at:

http://ndfd.weather.gov/technical.htm

If November 27, 2012, is declared a critical weather day, this
implementation may be postponed. In that case, users will be
notified of that decision via an updated Technical Implementation
Notice as far in advance as possible.
