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.

...SIGNIFICANT/SPECIAL FEATURES...

OTHER SPECIAL WEATHER STATEMENTS...

NEAR EQUATORIAL TROUGH...
The near-equatorial trough curves from EQ1302 through a disturbance
centered near 3N150E to end at EQ152E. Scattered showers and a few
thunderstorms are over a large area from just southwest of Chuuk 
Lagoon across southeast Palau and southeast Yap State. 

TRADE-WIND TROUGHS...
A weak trade-wind trough just southeast of Majuro runs from 6N173E
to EQ175 and is causing only spotty showers.

OTHER SYSTEMS...
A shear line cuts from 25N150E to 16N130E. Low to mid-level clouds
and patchy showers are found along and north of this line to beyond
25N.

A moist upper-level flow from the south and southeast is causing
some high level cloudiness over the Mariana Islands between 10N 
and 20N from 140E to 150E.

...DISCUSSION...
The near-equatorial trough along with a pattern of upper-level
divergence will continue to cause patchy showers over Western 
Micronesia. Models indicate the disturbance near 3N150E will drift
very slowly toward the west-northwest.

The trade-wind trough near Majuro is nearly stationary but some
some showers will spread west toward Kosrae.

The shear line has slowed a bit but is expected to drift toward
the Marianas during the coming days and could yet intensify
further later in the week.
