Subject: Implementing improved marine zone coverage for
 coastal waters along the Florida Panhandle effective
 December 5, 2017

Effective Tuesday December 5, 2017 at 200 pm Eastern Standard
Time (EST), 100 pm Central Standard Time (CST), 1900 Coordinated
Universal Time (UTC), NWS will realign marine zones within
Weather Forecast Office (WFO) Tallahassee and Mobile areas of
responsibility for coastal waters along the Florida Panhandle
to better align with the National Hurricane Center (NHC)
breakpoints. The changes involves the following marine zones:

The first change moves the westernmost edge of GMZ750 and GMZ770
from Destin to the Okaloosa and the Walton county line where the
new NHC breakpoint is defined.

The second change splits Coastal Waters from Apalachicola to
Okaloosa-Walton County Line out to 20 NM into two zones. The
zones will now be Coastal Waters from Okaloosa-Walton County
Line to Mexico Beach out to 20 NM, zone 750, and Coastal Waters
from Mexico Beach to Apalachicola out to 20 NM, zone 752.

The third change splits coastal waters from Apalachicola to the
Okaloosa-Walton County Line, 20 to 60 NM, into two zones. The
zones will now be coastal waters From Okaloosa-Walton County
Line to Mexico Beach ,20 to 60 NM, zone 770, and coastal waters
from Mexico Beach to Apalachicola 20 to 60 NM, zone 772.

The marine zone code and name GMZ635, Choctawhatchee Bay, will
be split into two sections: the western portion of the new
Choctawhatchee Bay marine zone on the Okaloosa county side will
be GMZ635, Western Choctawhatchee Bay. The eastern portion of
the new Choctawhatchee Bay marine zone on the Walton County side
will become GMZ636, Eastern Choctawhatchee Bay.
