Subject:   Winyah Bay, South Carolina, will transfer from a
           Marine Zone to Fire and Public Zones Effective 
           June 7, 2012
 
Effective Thursday, June 7, 2012, at 2 PM Eastern Daylight 
Time (EDT), 1800 Coordinated Universal Time (UTC), the NWS 
Weather Forecast Office (WFO) in Wilmington, NC, will transfer 
Winyah Bay from a marine zone (AMZ256) to fire (SCZ056) and 
public (SCZ056) zones.  Winyah Bay is largely closed off from 
the Atlantic Ocean and its weather is more like the adjacent 
fire and public zones than the marine zone it is currently in.

 

The modified zones are listed in Tables 1 and 2 below.  WFO

Wilmington will continue to issue forecasts and warnings

for the modified zones in Tables 1 and 2 via the products

in Table 3.
