Subject:  Changes to Coastal Marine Zone Boundaries Off

          Central California Effective December 3, 2013

 

Effective Tuesday, December 3, 2013, at 10:00 am Pacific

Standard Time (PST), 1:00 pm Eastern Standard Time (EST),

1800 Coordinated Universal Time (UTC), the NWS Weather Forecast

Office (WFO) in San Francisco/Monterey, CA (MTR) will reconfigure

marine zones PZZ570 - Point Arena to Pigeon Point 10 to 60 NM,

PZZ575 - Pigeon Point to Point Piedras Blancas 10 to 60 NM, and

PZZ530 - San Francisco, San Pablo, Suisun Bay and the West Delta.

 

Marine zone PZZ570 - Point Arena to Pigeon Point 10 to 60 NM,

will be split into two separate zones at Point Reyes. This

dividing line will match the dividing line currently used in the

inner zones (out to 10 NM). The current marine zone PZZ570 will

be reconfigured to extend from Point Arena to Point Reyes 10 to

60 NM. A new marine zone, PZZ571, will extend from Point Reyes to

Pigeon Point 10 to 60 NM.

 

Marine zone PZZ575, Pigeon Point to Point Piedras Blancas 10 to

60 NM, will be split into two separate zones at Point Pinos. This

dividing line will match the dividing line currently used in the

inner zones (out to 10 NM). The current marine zone PZZ575 will

be reconfigured to extend from Pigeon Point to Point Pinos 10 to

60 NM. A new marine zone, PZZ576, will extend from Point Pinos to

Point Piedras Blancas 10 to 60 NM.

 

The San Francisco Bay zone (PZZ530) will also be split into two

separate zones with the Bay Bridge as the dividing line. The

current marine zone, PZZ530, will encompass the San Pablo and

Suisun Bays and the West Delta along with the portion of the San

Francisco Bay that lies north of the Bay Bridge. A new marine

zone, PZZ531, will encompass the San Francisco Bay South of the

Bay Bridge. This marine zone configuration change is to better

serve marine users along the central California coast and the San

Francisco Bay. The smaller zones will result in forecasts that

are more representative of expected weather and wave conditions

due to local geography and the daily wind patterns through the

complex terrain of the San Francisco Bay.
