Additional Information
Products available in digital format
NWS Official Web Disclaimer

Analysis and forecast products are available on the MMAB web pages for ocean winds (both from analysis and satellite sensing), ocean waves, marine visibility (both coastal and open ocean), vessel icing, and sea ice. The products are at different levels of completeness or support, with

operational being the most supported,

experimental being intermediate, and

developmental the lowest. Developmental products are available only to people involved in product evaluation. Experimental products will replace the current operational products once they've been proven to be superior. In the mean time, they cannot be assumed with operational confidence to be produced, nor will the graphics necessarily be constructed or disseminated.

You can reach the products by selecting the name, which will take you to the appropriate page. The page will also describe the products and their use as well as including links to the images.

EXPERIMENTAL: Marine Summary Map

Marine Summary Figure

We produce a summary figure for northern hemisphere marine hazards. This summary is intended to be for 00 Z of the current day.
North polar view of the same information
South polar view of limited hazard information (please note that the southern hemisphere cannot include vessel icing hazards due to the absence of model guidance. Waves and ice, however, are still included.)
The valid date is given on the figure. Hazards currently included are:

Waves - greater than 5 meter significant wave height - Red
Vessel Icing - Dark Blue
Visibility - Visibility less than 3 nautical miles (5.6 km) - Aqua
Sea ice - Purple
Waves - greater than 2.5 meter (8 ft) significant wave height - Pale Red

Clicking on the name of a hazard in the above list will take you to the branch page which deals with that item in detail. Please note that only one hazard is marked on the figure. If two hazards are present, the one highest on the list is shown. Only very high waves (greater than 5 m) are shown in an area, for example, even if there is also limited visibility or vessel icing. Vessel icing is shown rather than limited visibility.

As this is an experimental product we are particularly interested in your comments on how to make it more useful. Please write Robert.Grumbine@noaa.gov with your suggestions.
