Tropical Weather Discussion
National Weather Service Tiyan GU
1004 AM ChST Wed Nov 26 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...

None.

...OTHER WEATHER SYSTEMS...

NEAR EQUATORIAL TROUGH...
Today the NET has shifted south a little, entering GUAM`s AOR at
3N130E and extending to EQ163E. No appreciable convection is
occurring along and north of this feature it our area, with
convection occurring along and south of the equator.

SURFACE TROUGHS...
A subtle trough extends northwest from EQ164E between Chuuk and
Pohnpei, ending near 9N153E. Scattered showers are occurring with
this feature, which is forecast to rotate south very slightly
while extending to near Yap in a couple days, as a weak
circulation potentially develops near 3N150E. This will help pull
deeper moisture northwestward toward Yap from the equator. This
may result in increasing convective coverage and vigor over the
next few days as the pattern develops/reorientates synoptically.

Another trough is located east of Kosrae, stretching north
from 4N166E to 10N170E, where it ends south of Utirik. Widespread
cloud cover with scattered showers are occurring, and this will
continue the next few days as it heads west.

TRADE-WIND SURGE...
The trade-wind surge continues to weaken and decrease in size, as
the pressure gradient weakens. Today, it`s found east of 172E
centered between 5N and 15N, where 15 to 20 knot winds and seas of
7 to 9 feet are located. This feature is expected to dissolve
during the next 24 hours, and this will likely be the last mention
of it.

TUTT...
The TUTT enters Guam`s AOR at 22N180 today, bypassing Wake Island
as it extends southwest, ending at a developing col that`s
centered between Chuuk and Pohnpei near 7N155E. Good divergence to
the south and east of this feature is allowing for widespread
clouds to continue, with scattered showers to continue developing
east of 160E, centered between 8N and 15N in a west-southwest to
east-northeast fashion. The TUTT is forecast to weaken and
dissolve the next few days as a broad area of high pressure
develops in an east-west orientation, centered across the northern
CNMI.
