Area Forecast Discussion
National Weather Service Tiyan GU
1027 AM ChST Sun Sep 9 2018

.Marianas Synopsis...
Andersen Air Force Base Doppler weather radar shows only a few
showers within the Marianas waters. The VAD wind profile indicates
east winds of 6 to 12 knots through the lowest 2 thousand feet of the
air. The buoys reveal combined seas of 3 to 4 feet composed mainly of
northeast trade-wind swell.

&&

.Discussion...
Focused mainly on the short term, the next 48 hours, which will
feature the passage of Tropical Storm Mangkhut, likely a typhoon by
that time. Still a fair amount of uncertainty in the track, as the
NavGem takes it near Tinian and the non-hydrostatic mesoscale model
takes it right over Guam. The key takeaway is that somewhere in the
Marianas forecast zones we are likely to see typhoon force winds, and
tropical storm force winds will cover much of the area.

&&

.Marine...
Winds and seas will build dramtically starting Monday afternoon.
They could take until Wednesday to settle down substantially.

&&

.Tropical systems...
Tropical Storm Mangkhut (26W) will move through the Marianas
overnight Monday night. It is strengthening and should pass through
as a typhoon. It is expected at some point to become a major typhoon.

&&

.Eastern Micronesia and Chuuk...
As Tropical Storm Mangkhut continues to move west-northwestward near
14N, its associated monsoon trough has lifted northwest of Chuuk and
Pohnpei. Modest monsoonal west to southwest winds south of the trough
can still spark a few showers and thunderstorms near Chuuk thru
Monday night. However, drier mid-level air advecting northward should
keep showers at isolated coverage. Farther east, a ridge of high
pressure southeast of Mangkhut should prolong fair weather near
Pohnpei thru Tuesday afternoon, and Kosrae until Monday night. This
same high will also bring similar conditions to Chuuk by Tuesday.

The latest ASCAT satellite imagery reveals a near-equatorial trough
extending east-northeastward from near Butaritari Atoll at 4N173E
thru the Date Line at 6N to beyond 8N165W. This feature will continue
to trigger periodic showers and thunderstorms near Majuro thru
midweek. As it gradually shifts westward over the next few days, it
will also impact Kosrae by Monday night, Pohnpei and Chuuk near
midweek.

&&

.Western Micronesia for Yap and Koror...
The broad but weak circulation near far Western Micronesia has
drifted to northwest of Koror near 9N133E. A modest monsoon trough
curves east-northeastward from this circulation, passing near Yap at
10N140E to Tropical Storm Mangkhut east of the Mariana Islands.
Gentle winds near this trough are expected to maintain an isolated-
shower regime for both locations thru Monday afternoon. As Tropical
Storm Mangkhut approaches the southern Mariana Islands, probably as
a typhoon on Monday night; it will enhance the monsoon trough across
far Western Micronesia. As a result, anticipate increasing shower
coverage, and building winds and seas near Koror and Yap starting
Monday night. As Mangkhut turns northwestward into the Philippine Sea
during midweek, a robust monsoon tail could form across far Western
Micronesia.

Seas and surf are going to build across far Western Micronesia
beginning Tuesday in response to the monsoon surge. There is a chance
for both seas and surf to reach hazardous levels.
