This bulletin, prepared by Dr. Y. Y. Chao of the Ocean Modelling Branch, Environmental Modelling Center, National Centers for Environmental Prediction, describes a new regional ocean wave model which encompasses the East Coast of the United States, the Gulf of Mexico, and portions of the northern Caribbean Sea.

The AFOS and DIFAX products for the Gulf of Mexico will continue until superceded by AWIPS, but with output from the new model. Also, bulletins in WMO GRIB format will be sent to AWIPS, Family of Services and the Global Telecommunications System. These bulletins will be available twice a day. The bulletin headers are:

where A, C, E, G, I-M stand for the 00-, 06-, 12-, 18-, and 24- through 48-h projections at 6-h intervals.
