NATIONAL WEATHER SERVICE MARINE PRODUCTS VIA EMWIN
the Emergency Managers Weather Information Network, is now evolving into
a fully operational and supported NWS service, in partnership with the
Federal Emergency Management Agency
and other public and private organizations.
EMWIN is a suite of methods of making available a live datastream of
basic text and graphic weather data, and providing access to stored sets of basic
data, using a variety of techniques and technologies. Each method has advantages
and disadvantages over the others, hence this multilayered approach to
enable multiple methods of availability. The EMWIN datastream includes
virtually all NWS products which are of potential interest to mariners.
EMWIN systems can also be programmed to sound an alarm in cases of severe
weather. EMWIN's present methods in use or
under development for disseminating the basic EMWIN datastream include:
Radio -- limited number cooperative VHF/UHF stations

Satellite -- GOES 8, GOES 9, etc.
Regrettably, radio broadcast of EMWIN via VHF/UHF to coastal areas is virtually
the current time. Cooperative arrangements with private and public organizations are
established to promote growth of a nationwide VHF/UHF EMWIN network. Direct Internet
access is also problematic for mariners at sea. EMWIN reception via the current GOES
network is technically challenging for ships as a directional antenna is

EMWIN's greatest immediate potential for mariners is for those having access to the
