Area Forecast Discussion
National Weather Service Tiyan GU
707 AM ChST Sat Dec 22 2018

.Marianas Synopsis...
Partly cloudy skies with moderate to fresh trade winds prevail across
the Marianas this morning. PGUA WSR-88D shows only spotty showers
over the region. Latest buoy observations show seas between 7 and 9
feet.

&&

.Discussion...
A much drier pattern is now in place across the Marianas and looks to
continue through the next week or so. Latest moddel guidance shows a
number of weak troughs moving through to the south of Guam, with only
a few showers possible over the islands.

&&

.Marine...
Observations from the Ipan and Ritiduian buoys show sea heights
between 7 and 9 feet this morning. Latest model guidance shows sea
heights remaining between 6 and 9 feet through at least the middle of
next week.

&&

.Eastern Micronesia...
Active ITCZ SSE of Majuro and east of date line will advance
westward thus bringing a lot of showers near and above the
forecast zones into early next week. An emerging surface trough
well SW of Majuro will extend northwest toward Kosrae between
Monday night and Tuesday. This will bring additional rainfall and
possible thunderstorms near and above Kosrae and Pohnpei through
at least Monday night or Tuesday. Hence, wet weather conditions
will linger over most of the region, and issuance of hydrological
products are encouraged to provide awareness about this expected
situation.

WW3 shows seas declining near 5 to 7 ft at Kosrae on Monday and
Tuesday, and about 1 to 2 ft below the previous combined seas
forecasted at Majuro for Monday and Tuesday. Have not made changes
to seas from the previous forecast package due to limited data
from Altimetry. A Small Craft Advisory was headlined for Pohnpei
today through tonight to reflect expected winds up to 25 kt. Also,
High Surf Advisory for Majuro continues through this evening and
through Sunday at Kosrae.

&&

.Western Micronesia...
The potential for heavy showers and isolated to scattered
thunderstorms are extremely possible for all 3 locations during the
next several days. Currently, a trade-wind disturbance and a weak
circulation SSW of Chuuk which connects to a near-equatorial trough
will sweep scattered to numerous showers and isolated thunderstorms
near and above Chuuk through Sunday. This same weather phenomena will
bring a lot of wet weather across Yap and portions of Koror between
Tuesday and Wednesday, and strong upper-level diverge will trigger
episodes of increasing thunderstorms near and above Yap. This
situation will require issuance of hydrological products for
respective locales as heavy rainfall pass through the region into
the new week.

WW3 now suggest a brief jump for sea heights at Koror and Yap
during Tuesday and Tuesday night and possibly through Wednesday
morning as a reflection of the expected impulse from the
circulation and trade-wind disturbance while crossing Yap and
Koror region. Also, WW3 show a slight increase in combined seas
for today through Sunday and Wednesday at Chuuk. Have not made
changes to seas at Chuuk as the latest Altimetry shows wave
heights up to 7 to 8 ft near Chuuk State. For this reason, will
keep an eye on this situation through this morning and provide
updates should sea heights rise.
