Tropical Weather Discussion
National Weather Service Tiyan GU
1111 AM ChST Tue Nov 3 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 continues to move into colder
waters, weakening due to upper-level wind shear and dry air. The
latest visible imagery shows In-fa located approximately 170 miles
southwest of Iwo To at 23.2N 139.3E, moving northwest at 6 mph.
Maximum sustained winds have decreased to 75 mph. Typhoon In-fa
will likely remain at or near low typhoon strength, before making
a northeastward turn and entering the northern Pacific, eventually
becoming 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-EQUITORIAL TROUGH...
A monsoon-like, near-equitorial trough
enters Guam`s AOR near 6N 132E and extends to a broad, weak
circulation southwest of Chuuk near 5.2N 150.8E. The trough
continues extending eastward through Kosrae, passing just south of
Majuro, and exiting the AOR near 3N 180. A broad area of
scattered showers and thunderstorms are found within the trough,
starting between 6N and the equator, extending eastward from 140E
to around 152E. A second broad area of scattered showers and
thunderstorms are located southeast of Kosrae, around 5.5N to the
equator, and 162E to around 170E.

TUTT...
A Tropical Upper-Tropospheric Trough with weak to
moderate upper-level support is found near 9.5N 166E extending
north-northeastward to around 19.3N 175E. The TUTT is expected to
move predominantly westward, with model guidance indicating a
decrease in upper-level support as it approaches the Marianas
later this week. Scattered showers and thunderstorms are
associated with the axis of this trough.
