Tropical Weather Discussion

Tropical Weather Discussion for the Western North Pacific between
the Equator and 25N from 130E to 180. The following information is
based on recent satellite imagery/data, weather observations, radar,
and meteorological analysis.

...SPECIAL FEATURES...

TROPICAL AND MONSOON DISTURBANCES...
A weak circulation is evident along the Near-Equatorial Trough (NET)
just S of Yap Proper, centered near 8N137E. Convection associated
with this feature will be included with the NET section below. This
feature remains poorly organized as it moves slowly WNW. Little to no
additional development is expected as the circulation continues on
its WNW trajectory.

...OTHER WEATHER SYSTEMS...

NEAR-EQUATORIAL TROUGH...
A NET enters the region near 6N130E, extending ENE to a weak
circulation centered just S of Yap Proper near 8N137E, then
continues E to another circulation centered just NW of Weno, Chuuk
near 9N151E. The NET then turns S to end near EQ151E. Scattered to
numerous showers and isolated thunderstorms are found along and S of
the NET across Palau, Yap and Chuuk State W of Weno. Little change is
expected in the strength of the NET, with no additional development
of the circulations as the NET remains quasi-stationary.

TRADE-WIND TROUGHS...
A trade-wind trough is seen to the SE of Weno, Chuuk, extending NNW
from near EQ157E to end near 7N153E. Scattered showers and isolated
thunderstorms are found with this trough just W of Nukuoro. The
trough will continue to move W, interacting with the S tip of the
NET, increasing convection S of Weno.

A very weak trade-wind trough is found between Pohnpei and Kosrae,
extending NNE from near EQ160E to end near 8N161E. A narrow band of
enhanced convergence just W of the trough is generating a few
enhanced showers just N of Pohnpei. The trough will continue its W
progression over the next couple of days with little change in
intensity.

An elongated trade-wind trough is found between Kosrae and Kwajalein,
extending NW from near 3N170E to near 10N164E, where it turns N to
end SSW of Wake Island near 18N166E. Spotty clouds and showers are
found along the trough. This feature will continue to move slowly W
over the coming days with little change to slight weakening as it
approaches Kosrae.

Another elongated trade-wind trough is found E of Majuro, extending
NNW from a weak circulation centered E of Butaritari near 4N177E to
another weak circulation centered NNE of Majuro near 11N173E. The
trough continues NE to end near 21N178E. Scattered to numerous
showers and isolated thunderstorms are found with the trough and
first circulation from near Butaritari ENE to the Date Line.
Scattered showers are also found along the trough and with the second
circulation found NNE of Majuro between 8N and 13N. Farther N, only
spotty clouds and showers are found along the trough.

The last trade-wind trough is seen E of the northern Marshall
Islands, extending NNW across the Date Line near 12N to end near
19N177E. Scattered showers and isolated thunderstorms are found along
the trough. The trough looks to continue W over the next few days,
eventually merging with the trough farther W.

TUTT...
A weakening TUTT enters the area near 25N179E, extending SW to a
weak cell centered NNE of Pohnpei near 13N160E, then continues WSW to
10N146E,continuing W to end near 11N140E. Only spotty showers are
found along most of the TUTT due to how weak the feature has become.
Enhanced divergence SW of the weak cell is generating a small band of
scattered showers and isolated thunderstorms near 11N from 150E to
155E. The TUTT and associated TUTT cell are expected to continue to
weaken over the next few days.

OTHER SYSTEMS...
A weak quasi-stationary front enters the area E of Minami Torishima
near 25N160E, skirting the N edge of the area near 23N, exiting the
region W of Iwo To near 25N140E. Scattered showers and isolated
thunderstorms are found along the front, with isolated thunderstorms
near and E of Minami Torishima. The front looks to slowly drift E
over the next few days as it continues to weaken.
