.Synopsis for Marianas Waters...
Gentle to moderate trades will prevail across the Marianas for
much of this week. Combined seas of 5 to 8 feet, comprised of a
weakening easterly swell, strengthening northerly swell, and
persistent westerly swell, are expected to persist for several
days while varying in strength throughout the week. While seas are
expected to remain below small craft advisory levels, seas will
continue to be choppy as these swells continue to mix.
