Tropical Weather Discussion
National Weather Service Tiyan GU
1125 AM ChST Fri Nov 7 2025

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 CYCLONES...
The latest satellite data shows that Tropical Storm Fung-wong is
currently centered near 11.4N 137.9E. Fung-wong is moving to the
northwest at 10 mph, with maximum sustained winds now at 50 mph.
The overall wind field for Fung-wong is very broad, with tropical
storm force winds extending outward up to 180 miles from the
center. Numerous to widespread heavy showers and isolated
thunderstorms is seen up to 380 miles from the center. Fung-wong
is expected to move west-northwest over the next few days with an
increase in forward motion. As Fung-wong continues moving across
the Philippine Sea, it will move into a more favorable
environment for development. Therefore, Fung-wong is expected to
strengthen over the next couple of days, possibly becoming a
typhoon late tonight or Saturday.

For more information on TS Fung-wong, please refer to bulletins
issued by Joint Typhoon Warning Center under WMO header WTPN32
PGTW and by the National Weather Service under WMO header WTPQ32
PGUM and WTPQ82 PGUM.

...OTHER WEATHER SYSTEMS...

MONSOON TROUGH...
The monsoon trough crosses into the AOR near 13N130E, extending
east to TS Fung-wong. It then continues east to end near 10N144E.
Most of the convection is associated with TS Fung-wong, however,
there is a band of convection to the south of Palau, with numerous
heavy showers and isolated thunderstorms are seen from 130E to
136E between 1N and 5N. Another band of convection is found well
south of Sorol and Eauripik where the monsoon winds are converging
with the trade winds to produce scattered to numerous showers. The
monsoon trough will continue to drift north as TS Fung-wong moves
toward the northwest. This will pull the convection farther north.

TRADE-WIND TROUGHS...
A trade-wind trough is seen just west of Weno, Chuuk, extending
northwest from near 5N153E to near 10N150E. Scattered showers are
found with this trough over Chuuk Lagoon. This trough will slowly
drift west and weaken as it is bumping into a weak ridge east of
TS Fung-wong.

Another trade-wind trough is found just west of Pohnpei, extending
north-northwest from near EQ159E to near 7N157E, then turns
northeast to end near 10N150E. Isolated showers and thunderstorms
are found north of Pohnpei, with scattered to numerous showers
found west through south of Pohnpei to the Equator. This trough
will slowly move west over the coming days and begin to weaken as
it moves into the area of the weak ridge east of TS Fung-wong.

A third weak trough is found east of Majuro, extending north from
near 4N174E to end near 8N174E. This trough is interacting with
the western end of a developing ITCZ to generate scattered showers
and isolated thunderstorms in a narrow band just southeast of
Majuro. The trough will continue to move west and strengthen as it
approaches Kosrae.

TUTT...
The TUTT enters the AOR near 20N180, extending southwest through a
weak cell centered near 19N179E to end northeast of Weno near
8N160E. Only spotty showers and thunderstorms are found with the
TUTT. The TUTT will continue to drift west and weaken over the
coming days.

...ITCZ...
A developing ITCZ is seen over far eastern Micronesia, extending
west across the Date Line near 7N to end south of Majuro near
6N171E. Patchy showers showers and isolated thunderstorms are
found with the ITCZ east of Majuro, with a narrow band of
scattered to numerous showers found south of Majuro. The ITCZ is
expected to continue to develop and spread weest over the coming
days with increasing convection along the band of convergence.
