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

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.
