Subject: Experimental U.S. Arctic Offshore Marine Zones to be added to the National Digital Forecast Database (NDFD)
and changes to existing NDFD parameters in other
Offshore zones effective May 18, 2011
Effective Wednesday, May 18, 2011, at 1800 Coordinated Universal
time (UTC), three new arctic marine zones will be added to the
NDFD on an experimental basis over the Alaska Region. NWS will
continue to produce the experimental text forecast for these
zones labeled PKZ500, PKZ505 and PKZ510. These marine zones will
be part of the larger experimental Alaska NDFD suite of graphical
forecasts currently available.
An updated map of all Alaska Region Marine Zones can be found at:
http://www.arh.noaa.gov/offshore.php
A compressed shapefile of the new Offshore Marine Zones can be found at:
http://weather.gov/geodata/catalog/wsom/data/oz02jn09.zip
The five weather elements that will be forecasted within these offshore
marine zones are Surface Wind, Surface Wind Gusts, Significant Wave
Height, Hazards, and Weather.
The production of NDFD data for the Offshore Marine Zones in the Gulf
of Alaska (PKZ310, PKZ351-352) and Bering Sea (PKZ411-414) will
continue but contain only the same five experimental elements available
in the new NDFD Arctic Offshore Marine Zones.
More details regarding these elements are available in the Product
Description Document in the online catalog of experimental NWS
products and services are available at:
http://products.weather.gov/PDD/AK_ExperimentalPDD_100630.pdf
With this implementation, forecasts for these new zones will be
available from NDFD in the following 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
AccessProtocol (SOAP)
- Graphics via web browser
All users can use the same methods they currently use to acquire
these forecasts.
Information on accessing and using NDFD elements is online at:
http://ndfd.weather.gov/technical.htm
Comments and feedback on these experimental Arctic Offshore
NDFD elements are welcome at:
http://www.weather.gov/survey/nws-survey.php?code=aondfd
GRIB2 users:
http://www.weather.gov/survey/nws-survey.php?code=ndfd-grids
Users OF XML SOAPservice:

These new Arctic Offshore Marine elements will remain
experimental until NWS assesses feedback and completes a
technical analysis. At that time, the NWS will determine
whether to move these experimental elements to operational
status, discontinue them, or revise and retain them as
experimental elements.
If May 18, 2011, is declared a Critical Weather Day this
implementation date will be postponed. Users will be notified
of that decision via another Technical Implementation Notice
and a new implementation date will be established.
