SUBJECT: Corrected: Changes in Offshore Waters Marine Zones

         For the Caribbean and Southwest North Atlantic

         and the Gulf of Mexico Effective April 3, 2012


NWS created an Offshore Marine Waters shape file for the Gulf of

Mexico, Caribbean, and Atlantic waters that incorrectly

eliminated the NWS Eastern Region (ER) coastal marine zones, 

20-40 nautical miles (nm) from shore, from the shape file. These

20-40 nm zones extend from Weather Forecast Office (WFO)

Charleston, SC, marine area of responsibility northward to WFO

Caribou, ME, marine area of responsibility.  This incorrect

shapefile was implemented operationally on April 3, 2012. 


The corrected zone map shape file is available for download from

the following web site:



NWS ER WFOs issue short term warnings for these 20-40 nm zones. 

For long term warning and forecast purposes, these areas are

shared with the NWS Ocean Prediction Center (OPC) offshore marine



graphic locations of these 20-40 nm zones from shore:


for graphic images of the offshore marine zones.


If you have any questions or comments about this shape file

please contact:
