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...
A NET extends from EQ173E to 4N161E. Scattered showers and
thunderstorms are noted along the NET and to just south of Kosrae. A
second NET extends from EQ166E to 4N145E. Southeasterly convergence
is seen to the south of the NET between 145E and 150E where robust
convection is ongoing. This pattern is expected to shift westward
over the coming days and could develop into an ITCZ across western
Micronesia. Periods of scattered showers will be possible for Palau
and Yap towards the middle and end of this week as
the pattern shifts westward.

TRADE-WIND TROUGHS...
A trade-wind trough is located between 13N157E to 6N151E. A second
trade-wind trough exists between 13N151E to 6N151E. A third
trade-wind trough is located between 16N138E to 6N136E. All three of
these troughs are bridge by a region of broad and weak circulations
extending from just south of Chuuk to just southeast of Palau.
Showers and thunderstorms have generally been isolated across the
trough axises except for where a weak circulation meets the NET around
5N146E. Scattered showers and isolated thunderstorms are seen where
the trade-wind trough and NET meet. These features will generally
move westward over the next few days.

TUTT...
A TUTT extends from 30N180 to 3N145E. A TUTT cell exists at 11N146E.
Isolated showers and thunderstorms can be seen near the TUTT cell.
This feature should continue to weaken as the southern half gets
cut off and shifts westward across the southern Marianas and western
Micronesia. This will increase isolated thunderstorms across these
locations over the next 24 hours. A second TUTT extends from 23N140E
to 12N129E. Scattered  showers and thunderstorms are seen just west
of the AOR near a TUTT cell at 22N127E. This feature should move
completely out of the AOR later today.
