Latest satellite loops shows showers associated with a trough
moving south of the Islands. This is due to a low pressure system
south of Tonga, which continues to pull moisture and instability
away from the territory as it migrates poleward. Hence, expect a
gentle breeze and isolated to scattered showers tonight through
Friday night.

Thereafter, a strong high pressure system will build near New
Zealand, thus pushing the aforementioned trough back north and
over the Islands Saturday. A slight uptick in showers is possible
for this time, though the trough isn`t expected to be active as
it moves across the territory. By Sunday, the ridge will move the
trough further north as it strengthens. Another round of breezy
winds will dominate in the area Monday through the end of the
week.

Latest observations shows seas have diminished below advisory
thresholds (below 8 feet) as winds have subsided. Expect calm
seas to remain through Saturday, before building Saturday
afternoon as a large set of swells moves in the area; a high surf
advisory and small craft advisory may be issued by this time.
However, choppy seas and high surfs will prolong through the new
week as winds build in the area Monday due to the ridge.
