Subject: Implementing Improved Marine Zone Coverage

         for the Mobile/Pensacola Coastal Waters:

         Effective October 2, 2012

 

Effective Tuesday, October 2, 2012, at 2:00 PM Eastern Daylight

Time (EDT) or 1200 Coordinated Universal Time (UTC) the NWS

Weather Forecast Office (WFO) in Mobile, Alabama, will

reconfigure its current marine zones for the Mobile/Pensacola

area. This reconfiguration will provide better forecast services

by realigning the coastal zones for climatological, geographical,

and bathymetric effects.

 

This change will provide enhanced forecasts for Mobile Bay; the

Mississippi Sound; Perdido Bay; Pensacola Bay, including the

Santa Rosa Sound; and Choctawhatchee Bay.

 

All current zones will be maintained except GMZ630 (Mobile Bay),

which will be divided into two zones: one for North Mobile Bay

and one for South Mobile Bay, split using a line between the

mouth of the Fowl River eastward to Point Clear.  In addition to

a new zone for Mobile Bay, four additional new zones will be

added, all separated out of GMZ650 and GMZ655 (see Tables 1 and

2), including one for Perdido Bay, which will incorporate Wolf

Bay into the zone.

 

Table 1 lists all the current marine zones and corresponding

Universal Geographic Codes (UGC) for which WFO Mobile issues

forecasts and warnings. 

 

Table 2 lists all the marine zones and corresponding UGCs for

which WFO Mobile will issue forecasts and warnings effective

October 2, 2012.

 

Table 3 lists all the products issued by WFO Mobile that will be

affected by the marine zone changes.
