and meteorological analysis.

...SPECIAL FEATURES...

None.

...OTHER WEATHER SYSTEMS...

TRADE-WIND TROUGHS...
A series of trade-wind troughs are seen across the region. The first
extends from 25N173E to 15N175E. Isolated showers are seen along this
trough, but satellite shows increasingly agitated cumulus over the
last few hours.

The second trough is just east of Majuro and extends from 15N169E to
5N173E. Scattered to numerous showers are seen just east of Majuro.
This trough will assist in bringing numerous showers to Majuro and
scattered showers to Kosrae this weekend.

The third trough extends from 20N156E to 7N161E or just north of
Kosrae and just east of Pohnpei. Some scattered showers are seen along
10N just northeast of Kwajalein and north of Kosrae. This feature may
bring scattered showers to the Marianas early next week.

The final trough is just east of Yap Proper. Isolated showers and
storms are seen outside of Yap`s coastal waters. The trade-wind
troughs will generally move westward over the next few days.

TUTT...
A TUTT lies just west of the Marianas extending from 20N142E to
EQ145E. Isolated showers and thunderstorms are seen along the TUTT
to the west of the Marianas. This feature will drift westward this
weekend before weakening early next week.

...ITCZ...
The ITCZ has pulsed up this morning with a couple of pulses in
Micronesia. The first pulse is just east of Majuro and contains
scattered to numerous showers moving westward towards the RMI. The
second pulse is across Chuuk State with a focus over Weno. Scattered
to numerous showers are seen moving westward across Chuuk State. The
ITCZ looks to break down into trade-wind troughs this weekend before
re-establishing itself in eastern Micronesia early next week.
