          New England and West Central North Atlantic,
          and for the Washington, Oregon and California Waters
          in the Pacific Ocean Effective April 1, 2014

Time (EDT) or 1800 Coordinated Universal Time (UTC), the Ocean
Prediction Center (OPC) of the National Centers for
Environmental Prediction (NCEP) will reconfigure its marine
zones for the offshore waters in the both the Atlantic and
Pacific Oceans. The Atlantic offshore waters include New England
and the west central North Atlantic. For the Pacific this
includes the offshore waters of Washington, Oregon and
California.

offshore waters and 5 marine zones covering the Pacific offshore
waters. These zones will be reconfigured into 18 for the
Atlantic offshore waters and 19 marine zones to cover the
Pacific offshore waters. Marine observations, local effects, and
customer feedback all indicate that the current marine zones are
too large to provide the necessary detail for the marine
community. This reconfiguration will serve to improve the
precision of marine warnings, forecasts and other services by
allowing forecasters to be more area specific.

Customers must reprogram affected hardware and software to
continue correctly processing the products listed in Table 3.

Also customers using a graphical representation of these zones
must download an updated marine zone map shapefile to correctly
depict the marine forecast areas for the Atlantic and Pacific
Ocean offshore marine zones.

An updated marine zone map shapefile containing the new zones
effective April 1, 2014 is available for download from the
following website:

To meet the time constraints for broadcast via U.S. Coast Guard
NAVTEX, the NAVTEX products will combine the forecasts for the
zones so are similar to the NAVTEX forecasts before
reconfiguration.

To meet the time constraints for voice broadcast via the U.S.
Coast Guard, four new products will be made available as listed
in Table 4.  These products will combine forecasts for the
18 zones in the Atlantic and 19 zones in the Pacific in such a
way that they will be similar to the Offshore Waters Forecasts
before reconfiguration.
