NATIONAL WEATHER SERVICE MARINE PRODUCTS VIA USCG VHF VOICE

Ch 16    156.8 mHz VHF FM
Ch 22A 157.1 mHz VHF FM

The U.S. Coast Guard broadcasts coastal forecasts and storm Warnings of interest to the mariner on VHF channel 22A following an initial announcement on VHF channel 16. These forecasts are produced by local National Weather Service Forecast Offices.  The USCG VHF network provides near continuous coverage of coastal U.S., Great Lakes, Hawaii, and populated Alaska coastline. Typical coverage is 20 nautical miles offshore, but can be significantly greater. Visit the U.S. Coast Guard Maritime Telecommunications Information webpage for further information on U.S. Coast Guard telecommunications including maps showing areas of VHF coverage and Rules Which Require Listening to your VHF Marine Radio. See tables below for a listing of current broadcast schedules of U.S. Coast Guard Group stations performing VHF voice broadcasts.

In areas where NOAA Weather Radio broadcasts provide complete overlapping coverage of the U.S. Coast Guard VHF network, the U.S. Coast Guard may elect to broadcast warnings only and not routinely broadcast NWS marine forecasts.

Refer to NGA Publication 117, which is updated through the Notice to Mariners, for the latest official listing of U.S. Coast Guard broadcast schedules. The British Admiralty List of Radio Signals , is an excellent reference source for weather broadcast information.

All NWS marine forecasts rely heavily on the Voluntary Observing Ship (VOS) program for obtaining meteorological observations.
