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 Alaska
         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:

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.
