Beware of hypothermia during these cooler months. Did you know your body can cool 25 times faster in water than in air? That water does not need to be very cold to endanger you?

What is a "Marine Zone Forecast"?
What is a "Marine Point Forecast"?

How can I get a marine forecast via zip, city, or lat/lon?

Did you know that the height of some individual waves may be twice the height of the forecast seas? And may present an even greater danger near shore?



The National Weather Service's Family of Services (FOS) is made-up of multiple data streams of meteorological and hydrological messages. FOS serves mass media (newspapers, radio stations, TV, etc.) emergency management agencies and private weather services. It is not suitable for mobile platforms such as ships.

FOS is accessible via dedicated telecommunications access lines in the Washington, D.C., area. All FOS data services are driven by the NWS Telecommunication Gateway computer systems located at NWS headquarters in Silver Spring, MD.

Users may obtain any of the individual services from NWS for a one-time connection charge and an annual user fee. Several private companies subscribe to the FOS and then resell the data as received and/or provide value-added information services for their customers.

The FOS includes the following services:

RADAR Products Service (RPS) The Radar Products Service (RPS) will provide direct user access to WSR-88D products in real-time. All radar products that the NWS is centrally collecting will be available on the RPS. You can obtain additional information about RPS from the Radar Product Central Collection/Distribution Service web site.

Server Access Service (SAS)
Provides access to the NWSTG networks and resources that reside there, in particular the File Server.
