Subject:  Changes in Offshore Waters Marine Zones for the

          New England and West Central North Atlantic,

          and for the Washington, Oregon and California Waters

          in the Pacific Ocean Effective April 1, 2014

 

Effective Tuesday, April 1, 2014, at 2:00 pm Eastern Daylight

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.

 

Currently there are 8 marine zones covering the OPC Atlantic

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.

 

Table 1 lists the current marine zones and corresponding UGCs

for which OPC issues forecasts and warnings.

 

Table 2 lists the marine zones and corresponding UGCs for which

OPC will issue forecasts and warnings effective April 1, 2014.

 

Table 3 lists all of the products issued by OPC that will be

affected by the marine zone changes. 

 

Table 4 lists future product headers for USCG voice broadcasts

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:

 

www.nws.noaa.gov/geodata/catalog/wsom/html/marinezones.htm

 

 

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.
