.Marianas Synopsis...
Moderate trade winds and a few sprinkles are present across the
Marianas this morning. The buoys are indicating seas between 3 and
6 feet.

&&

.Discussion...
Only minor changes were made to the forecast. Satellite shows mostly
clear skies this morning, so have not mentioned anything more than
a slight chance of light showers for today. But have left isolated
showers in for Tuesday morning, and the rest of the forecast is the
same as before. Moisture should gradually increase from Wednesday
night on, but no major rain events are expected over the next week.

&&

.Marine...
Moderate seas and winds will persist with only minor changes the
rest of the week. The rip risk will remain moderate.

&&

.Eastern Micronesia...
12Z ASCAT pass shows fresh trades across the Marshall Islands while
moderate trades are seen at Kosrae and Pohnpei. IR satellite shows
scattered showers and a few thunderstorms at Kosrae and Pohnpei,
while drier weather persists at Majuro. This convergence zone of
showers and thunderstorms at Pohnpei and Kosrae will lift slowly to
the west-northwest, with fresh northeast trades to the north and
gentle to moderate winds to the south. Little change is expected
through the weekend as a relatively wet trade-wind pattern will
continue south of 10N. A surface trough this weekend could bring
more showers to the Marshall Islands. However, much-needed rainfall
is not likely for the Marshall Islands north of 10N this week.

&&

.Western Micronesia...
Moderate trades are seen across Palau, Yap and Chuuk this morning.
IR satellite imagery shows showers and thunderstorms near and south
of Chuuk Lagoon associated with a circulation centered near 4N153E.
Isolated showers and thunderstorms near Yap and Palau along a weak
surface trough are in a lull this morning. Expect only isolated
showers today at both locations. Showers and thunderstorms near
Chuuk and Pohnpei will maintain wet conditions at Chuuk through
Tuesday night. The circulation south of Chuuk will bring showers
and thunderstorms to Yap and Palau by midweek. Significant
development is not expected with this circulation at this time.
Drier weather will return to Yap and Palau by the end of the week.
