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 NOAA Weather Wire Service (NWWS) is the primary telecommunications network for NWS forecasts, warnings and other products to the mass media (newspapers, radio stations, TV, etc.), emergency management agencies, and private weather services. Receiving systems for mobile platforms such as ships are not readily commercially available.

The NWWS satellite communications system is operated by DynCorp(previously GTE/CONTEL/ASC), under contract to the NWS. The system uses satellite transmitting (i.e. "uplink") equipment at more than 20 major NWS forecast offices throughout the continental U.S., Alaska, Hawaii and Puerto Rico. Each uplink site transmits NWS-generated weather information products to DynCorp which are then re-broadcasted via satellite to more than 400 users. Users then have access to this broadcast data stream of NWS products.

More than 6,400 individual products per day are transmitted. To use the system, users must obtain the equipment needed to receive the data broadcast from the system contractor.

The NWWS Data Product Master Database lists products available via the NOAA Weather Wire Service.
