Tropical Cyclone (TC) Vaianu, centered west of Fiji will remain
far away from the territory through the week. No direct impacts
are expected from this system, however, passing showers
(associated with a trough) is possible at times. Latest water
vapor satellite shows most of the moisture in the region being
absorbed into TC Vaianu. This leaves the Samoa Island chain in a
dry and stable airmass. Hence, rainfall amounts are expected to
remain light through the forecast period, and no flash flooding
concerns are anticipated. Additionally, a gentle breeze will
persist through the new week.

Seas continue to trend below advisory thresholds as south swells
have subsided. Wave heights observed at the Aunu`u PacIOOS buoy
hold within the range of 6 to 8 feet. However, conditions will
continue to subside through Thursday as no significant swells or
winds are expected. Hence, the high surf and small craft
advisories have been dropped. By Friday and into the weekend,
another south swell may elevate seas back to 6 to 8 feet and
persist through at least Monday.

.PPG WATCHES/WARNINGS/ADVISORIES...
