Area Forecast Discussion
National Weather Service Tiyan GU
650 AM ChST Mon Apr 23 2018

.Marianas Synopsis...
Partly cloudy skies, isolated showers and moderate to fresh trade
winds prevail across the Marianas. Latest buoy observations show seas
between 5 and 7 feet.

&&

.Discussion...
The forecast remains unchanged over the next week. No organized
systems are expected to affect the Marianas. Partly cloudy skies
will become mostly cloudy by Thursday. Isolated showers and slightly
diminishing winds are expected through the week.

&&

.Marine...
Marine conditions will remain fairly benign over the next 5 days.
Moderate to fresh winds will decrease slightly to mainly moderate,
though occasional fresh winds are possible through the end of the
week. A small north swell is expected to move into the region tonight
and continue through midweek. This small swell will likely increase
the rip tide risk to moderate for north facing reefs Tuesday.

&&

.Eastern Micronesia...
Surface troughs are found near Pohnpei and just east of Majuro.
Showers and thunderstorms will gradually increase near Kosrae today
and continue tonight before diminishing Tuesday. The trough near
Pohnpei will be slow to move westward, thus keeping the showers off
to the east in the short term. Scattered showers are expected by
midweek. A slightly unstable pattern will remain at Majuro today,
promoting showers there. Conditions will quiet this evening and for
midweek, but more showers are expected late in the week.

&&

.Western Micronesia...
A near-equatorial trough extends along 2N to a circulation SW of
Chuuk near 2N146E. Another surface trough is found just east of Yap.
Models keep the circulation in the same general area for much of the
week with little westward movement. The trough east of Yap will bring
an increase in clouds and isolated showers in the short term, but dry
weather will be the norm this week there and at Koror. Koror will
have a few more clouds and showers later in the week as the near-
equatorial trough lifts northward slightly. Chuuk weather will be dry
to start the week, but as the weakening surface trough near Pohnpei
moves west, there will be a small chance for thunderstorms around
midweek. More showers and thunderstorms are expected late in the week
as the near-equatorial trough approaches the area.

.GUM WATCHES/WARNINGS/ADVISORIES...
GU...None.
Marianas Waters...None.
