Subject:   New Marine Zones for the Niagara River Effective

           April 5, 2011


Effective Tuesday, April 5, 2011 at 200 PM Eastern Daylight

Time (EDT) or 1800 Coordinated Universal Time (UTC) the

NWS Weather Forecast Office in Buffalo , NY , will segment

its current marine forecast for the Niagara River . This will

result in changes to marine zone boundaries, marine zone names,

and marine zone Universal Geographic Codes (UGC).  These

changes will allow WFO Buffalo to provide more area specific

marine weather forecasts, watches, warnings, and advisories

for the Niagara River .


On April 5, 2011, the current marine zone LEZ020 Upper

Niagara River and Buffalo Harbor will be split at Niagara
into Upper Niagara River (marine zone LEZ020) and
