MARINE
Elevated seas on the ocean will continue into tonight, but will be subsiding. A period of sub-sca conds then follows late tonight through Saturday morning before 25kt+ gusts develop in the afternoon on the ocean, then on the other waters Saturday night. After collaboration with WFO BOX, have decided to not stretch the SCA on the eastern ocean waters to cover the 12 hour or so periods of sub- advisory conditions, and allow for the overnight shift to issue SCAs as appropriate (including for the non-ocean waters), figuring ocean seas will be below 5 ft by 06z tonight. SCA will probably need to be extended into Sunday and Monday as the pressure gradient strengthens, producing a gusty westerly flow.
