.Synopsis for Marianas Waters...
Moderate trade winds will prevail across the region today, becoming
gentle to moderate toward the weekend. Combined seas of 6 to 8 feet
will gradually decrease by 1 to 2 feet toward the end of the week, as
the elevated trade swell and wind waves continue to become more
relaxed. Although sea conditions remain below levels hazardous to
small craft, seas will remain choppy for the next few days,
especially over eastern coastal waters.
