.DISCUSSION...
A rather dry air mass remains over the area as a high pressure
system to the south transports cooler temperatures and a gentle
breeze across the islands. These stable conditions are reflected
on the upper air observations (RAOB) from this afternoon (30/00Z).
Model projections show the high pressure system increasing east-
southeast winds to a moderate to fresh breeze on Saturday, peaking
at a strong breeze on Monday through the middle of the week.
Showers embedded within the east-southeast wind flow will move
across the territory from time to time, tonight through Saturday
night. Model data shows a trough to the north descending over the
area Sunday night through Monday night. This will increase the
potential for showers. Winds will likely remain at a strong breeze
thereafter, decreasing to a moderate flow on Thursday with
diminishing showers.

Thus, expect strong winds with embedded scattered to numerous
showers for the weekend into the new week. Alerts will be issued
as warranted.

.Marine...
Observatins from the PacIOOS buoys (Aunu`u and King-Poloa) show an
uptick in wave heights, prompting the issuance of advisories for
small crafts and high surfs for American Samoa coastal waters and
shores. Model data have been consistent in bringing this large
south swell generated by the aforementioned high pressure system
to the south. Due to the long-distance fetch of this swell, wave
periods have reached more than 15 seconds long, a signal for surf
enhancement and strong rip currents. Also produced by this system
are gentle to moderate easterlies expected to increase to a fresh
to strong breeze over the weekend. The large swell and strong
winds are expected to linger in the area through at least the new
week. Therefore, the threat of hazardous seas, dangerous surfs,
and deadly rip currents is expected for tonight through at least
the new week.
