.SYNOPSIS...North winds to be light to gentle in all waters 
through the morning. Lower short period seas are mixing with a 
dominating mid period northwest swell around 5 feet and another 
mid period southwest swell around 3 feet. Though not too steep, 
these opposing, perpendicular swells still make for a chaotic sea
state. Moderate to strong north winds gradually rebuild first in 
the southern outer waters tonight before moving northward over the
weekend. Short period seas will rise in response.
