Tropical Weather Discussion
National Weather Service Tiyan GU
1046 AM ChST Mon Dec 8 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 enters Guam`s AOR at 5N130E and extends east to a
small circulation that has developed near 5N140E. It (the NET)
then continues southeast to EQ170E. Mostly cloudy skies with
scattered showers (locally numerous) are continuing to develop
near the NET, and this looks to be the case the next few days as
the NET gradually becomes more east to west orientated near the
equator by the latter half of the week.

TRADE-WIND SURGE...
The trade-wind surge has expanded today, although the areal
coverage of 20 to 25 knot winds has reduced significantly. In
general, a broad area of 15 to 20 knot winds extends southwest to
northeast from 6N to 23N, east of 155E. This surge is expected to
continue weakening the next few days as the pressure gradient
weakens some. Seas are generally in the 6 to 9 foot range in these
areas.

OTHER SYSTEMS...
A cold front enters Guam`s AOR at 25N150E, transitioning to a
shear line as it extends southwest, passing through the northern-
most portions of the CNMI, before exiting Guam`s AOR at 17N130E.
Mostly cloudy skies with scattered showers continues to develop
along and behind this feature. This will continue to be the case
the next few days as the shear lines slowly settles south before
stalling.

The shear line across Eastern Micronesia discussed yesterday has
merged with the NET today.
