See the NWS Marine Weather Serviceshomepage which contains information on the dissemination of NWS marine weather forecasts including frequency and broadcast schedule information as well as links to products and related information.

National Weather Service Coastal and Offshore forecast products listed on this webpage are subdivided by zone, each identified by a Universal Generic Code(UGC) e.g. ANZ050, and a Special Area Messaging Encoder (SAME) code, e.g. 073050. SAME codes are used to program SAME-capable NOAA Weather Radio receivers to receive alert messages for user-specified areas.
