Tropical Weather Discussion
National Weather Service Tiyan GU
1104 AM ChST Wed Nov 4 2026

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...
Typhoon In-fa strengthened despite moving towards colder waters.
The latest visible imagery shows In-fa located approximately 175
miles west of Iwo To at 24.4N 138.6E, moving north at 7 mph.
Maximum sustained winds have increased to approximately 100 mph.
Typhoon In-fa will likely remain at low-mid typhoon strength as it
turns northeastward and enters the northern Pacific, and is
expected to weaken as it moves out of Guam`s AOR, before
transitioning into an extratropical cyclone.

For more information please refer to bulletins from the Joint
Typhoon Warning Center under WMO header WTPN31 PGTW and from the
National Weather Service under WMO header WTPQ31 PGUM.

...OTHER WEATHER SYSTEMS...

NEAR-EUQITORIAL TROUGH...
A monsoon-like, near-equitorial trough enters Guam`s AOR near
4.5N 130E, extending eastward through Kosrae, passing just south
of Majuro, and exiting the AOR near EQ180. A small area of
disorganized scattered showers and thunderstorms are found within
the trough, starting around 3.0N 133E, extending eastward to 4N
141E. A second area of disorganized scattered showers and
thunderstorms are found within the trough, starting around 1.0N
158E, extending east-northeastward to 3.0N 166E. Between these two
areas, small pockets of locally isolated showers and
thunderstorms are also found.


TUTT...
A Tropical Upper-Tropospheric Trough with very weak upper-level
support is found near 12.0N 162E extending north- northeastward to
around 20.2N 168E. The TUTT is expected to move predominantly
westward, with model guidance indicating a further decrease in
upper-level support as it approaches the Marianas later this week.
Scattered showers and thunderstorms are associated with the west
axis of this trough.
