...SPECIAL FEATURES...

None.

...OTHER WEATHER SYSTEMS...

TRADE-WIND TROUGHS...
A trade-wind trough runs from EQ137E to 3N130E then farther north and
west. Scattered showers and isolated thunderstorms are seen in far
southern Republic of Palau such as Tobi and Helen`s Reef (Hatohobei),
and far southern portions of Yap State. This feature is expected to
shift slowly westward with little change of intensity.

Another trade-wind trough stretches from 2N148E to 16N146E, near
Saipan. Scattered showers are found near and west of the Marianas,
with a thunderstorm north of Yap. This feature is forecast to move
westward with little change of intensity.

A third trade-wind trough curves from 11N158E to 17N157E. Scattered
showers are found north of Pohnpei. This trough is expected to move
westward with little change of intensity and could affect the
Marianas in a couple of days.

A fourth trade-wind trough reaches from EQ175E to 10N174E. Scattered
showers are found in the eastern Marshall Islands including Majuro.
This trough is also forecast to move westward with little change of
intensity, and could affect Kosrae Wednesday.

OTHER SYSTEMS...
A cold front cuts from 25N145E to 18N130E then extends further
westward. Extensive low to mid-level clouds and patchy showers are
noted along and up to 300 miles north of this boundary. The front has
lost most of its southward momentum, so it is expected to move mainly
eastward with little change of intensity through Wednesday.
