.DISCUSSION...
A surface trough just north and east of the area will continue to
move closer to the territory, tonight. This has the potential to
increase showers for the next 12 to 16 hours. However, the latest
model data, upper air observations (RAOB), and satellite imageries,
show stable and dry atmospheric conditions remaining over the
islands for tonight through at least midweek. Also, the moderate
to fresh (15 to 20 mph) easterlies will aid in pushing the
associated clouds further west, only posing a minor threat of brief
showers over the area from time to time.

By Thursday into the weekend, winds will slightly decrease as it
turns southeast. Additionally, the high pressure system to the
south will move further east as another high pressure system from
the southwest migrates east. This will allow the aforementioned
trough to move over the islands and southeast winds to slightly
increase again to a fresh breeze. Thus, expect an increase in
showers and winds by the end of the forecast period.

.Marine...
Observations from the PacIOOS buoys show heights within the small
craft advisory threshold (8 feet and/or 20 knots). Model data
show these heights remaining for tonight through at least Tuesday
night. By midweek, seas are projected to subside to more
favorable conditions. However, by the end of the forecast period
(Saturday), model data shows a large south-southwest swell moving
into the area, likely building seas again to advisory criteria. In
the meantime, the threat for small crafts remains in effect.
