Marine forecasts and graphical products by e-mail
This free service is provided by the National Weather Service in Washington as a contribution to Safety of life at Sea.
The service provides the facility to request a forecast or graphic. The requested item is then returned to the sender or a designated recipient by return (usually within an hour, but in practice the reply is usually within minutes).
Keep in mind when using the service at sea via a satellite link that text messages
are quite short but graphics (charts) are much larger and therefore would be
prohibitively costly at the present time to access in this way. But ashore the
transfer of charts by request is simple and quick.
A full description of the service is provided by the NWS and it is worth reading that text especially if forecasts for waters outside of the North Atlantic are required.
