Subject: Implementing Improved Marine Zone           
         Coverage for the Florida Keys
         Coastal Waters: Effective July 7, 2011
 
Effective Thursday July 7, 2011, at 200 PM EDT or 1800 
Coordinated Universal Time (UTC) the NWS Weather Forecast 
Office (WFO) in Key West, FL, will reconfigure its current 
coastal waters zones for the Florida Keys. 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 Hawk Channel, 
the smaller zones between Key West and the Dry Tortugas, more 
consistency with bathymetry across Florida Bay and Gulf zones, 
and remove the zone boundaries near Key West Harbor.
 
All current zones will be realigned, except GMZ072 (Straits of 
Florida from Ocean Reef to Craig Key 20 to 60 nm out) and GMZ073 
(Straits of Florida from Craig Key to west end of Seven Mile 
Bridge 20 to 60 nm out). Four additional new zones will be added.
 
Table 1 lists all the products issued by WFO Key West that will 
be affected by the marine zone changes.  
 
Table 2 lists all the current marine zones and universal 
Geographic codes UGCs for WFO Key West.  
 
Table 3 lists all the marine zones and UGCs for which WFO Key West 
will issue forecasts and warnings effective July 7, 2011.
