.Marianas Synopsis...East wind and a partly to mostly cloudy sky
will prevail today. Once again, there is a chance of isolated
showers.

.Discussion...
A shear line across the Marianas has kept a mostly cloudy sky
over the area and brought some showers on Wednesday. A similar
scenario is anticipated today. Moisture is confined to the lowest
levels with dry air aloft. East wind of 15 to 20 mph is expected
through tonight before decreasing.

&&

.Marine...
The small craft advisory will remain in effect with combined seas
over 10 feet at Ritidian and Tanapag and over 7 feet at Ipan.
North swell should increase to around 4 feet. Easterly will be at
least 6 feet through Friday.

&&

.Eastern Micronesia...
Converging trade winds are bringing mostly cloudy skies with
isolated showers into Majuro today. This will likely persist
through Friday night before clearing out again. The Intertropical
Convergence Zone has sagged south of Kosrae, allowing isolated
showers and thunderstorms today. Scattered showers should move
back in tonight, then remain through Friday night also. The ITCZ
also sagged south of Pohnpei, and is likely to remain there.
Similarly, the weak tropical disturbance spinning up on the ITCZ
is expected to pass south of Pohnpei.

Sea heights are elevated, but are only reaching hazardous levels
at Kosrae. A high surf advisory will remain in effect there
through at least tonight. Seas will be slow to diminish though,
and combined with king tides of up to 6 feet, could still produce
minor coastal inundation through Friday at Kosrae and Saturday
morning at Majuro.

&&

.Western Micronesia...
Convection has worn itself out today in Palau, however is expected
to return tonight. It will then remain in the area through Friday
night. The bulk of it is still expected to pass south of Yap, with
perhaps just a few thunderstorms along the northern edge of the
disturbance through Saturday. The disturbance currently just south
of Pohnpei is expected to similarly pass just south of Chuuk.

Sea heights also remain elevated in Western Micronesia. They will
start to slowly diminish on Sunday. Therefore, no advisories are
anticipated for Western Micronesia through the weekend at least.

&&

.GUM WATCHES/WARNINGS/ADVISORIES...
