Tropical Weather Discussion

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...
The NET enters Guam`s AOR at 10N130E and extends east to a weak,
but long-lived and persistent circulation north of Koror near
10N135E. This feature has been slow-moving and continues to show
scattered showers and isolated thunderstorm development within 200
miles of its center. This feature is moving off to the west but
will continue to bring convection to northern Palau for the next
24 to 48 hours. Westerly flow with this portion of the net is
quite weak as the inflow into the LLCC north of Koror dominates
the low-level wind fields.

The NET then turns southeast to a col south of Pohnpei near
5N158E, before coning east as it passes by Kosrae and Majuro to
the Date Line and beyond. Scattered showers and a few
thunderstorms continue to develop along and near the NET. However,
winds are very light and westerly flow may become variable south
of the NET for the next 72 hours. Heading towards the weekend,
the NET looks to strengthen with improved westerly flow
continuity and strength, which may also allow for an uptick in
convection and perhaps an eventual circulation forming somewhere
east of 165E.

SURFACE TROUGHS...
A surface trough is easily seen in the streamlines, extending
southeast from near Bikini Atoll to Jaluit in the RMI, where it
intersects the NET. However, no appreciable convection is noted
and this looks to be the case the next few days as it heads west.

OTHER SYSTEMS...
A weakening cold front enters Guam`s AOR near 25N175E and extends
southwest to 21N160E. Scattered showers continue to develop near
and behind this feature, which will continue to dive southeast
over the next 48 hours.

The cold front then transitions into a shear line as it "flattens
out", extending west through the northern CNMI to 19N140E, where
it ends. No appreciable convection is observed along this shear
line, and this is expected to continue the next 48 hours as this
portion of the front washes out.
