SUBJECT:  Soliciting Comments until March 15, 2016 on the

          expansion of the Operational Marine Forecast

          Matrix produced by WFO Honolulu to National Scope


Effective immediately and continuing through Tuesday March

15, 2016, NWS is seeking comments on its proposal to expand

the Marine Forecast Matrix (MFM) to national scope.


The MFM is an alphanumeric text product that provides a

tabular forecast of wind direction and speed, wind gust,

swell direction, swell height, swell period, wind wave

height, significant wave height, cloud cover, probability

of precipitation, and precipitation type.


At present the MFM is only issued by the NWS Weather

Forecast Office (WFO) in Honolulu, HI. The NWS is

considering expanding this product to all marine WFOs. For

the latest issuance of this operational product by WFO

Honolulu, see the link below.

Please provide comments on this proposed expansion via a

short online survey at:


After March 15, 2016, the NWS will assess any comments and

determine whether to expand the MFM to other marine WFOs.


If NWS decides to expand the MFM to other marine WFOs, a

Service Change Notice will be issued announcing the

effective date and the additional participating WFOs.
