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 near-equatorial trough lies just south of the Republic of

Palau, running from EQ129E to 2N136E to far southwest of Pohnpei

at EQ150E. Just patchy showers are found near the NET, mainly on

the north side.



TRADE-WIND TROUGHS...

A trade-wind trough just south of Koror runs from 6N132E to 4N136E.

Scattered showers are seen near this trough.



Another trade-wind trough far southeast of Majuro is causing 

scattered showers near Tarawa eastward to beyond the Date Line.



TRADE WIND CONVERGENCE ZONES...

Sightly stronger trade winds over southeast parts of Micronesia 

are causing a convergence boundary that runs from southeast of

Weno Chuuk at 7N155E across southern Pohnpei State to south of 

Kosrae at 1N163E. Cloudiness and patchy showers are seen along and

north of this boundary.



Also, trade winds continue surging across the Wake Island area 

and in particular are triggering scattered showers within about 

50 miles of a line just south of Wake from 18N158E to 17N172E.



...DISCUSSION...

The near-equatorial trough doesn't seem very strong, and is not

expected to change much in the coming days.



The two trade-wind troughs over southern Palau and near Tarawa 

are expected to gradually move westward and perhaps a little

toward the northwest.



The convergence boundary over Eastern Micronesia has spread out 

and weakened a bit since yesterday and cloud cover across this 

region has become more extensive.



The trade-wind convergence boundary just south of Wake Island has

changed configuration slightly and drifted toward the southwest.



Otherwise, to our north, a high pressure ridge remains stretched 

east to west along and just north of 25N.
