Area Forecast Discussion
National Weather Service Pago Pago AS
220 PM SST Wed Oct 21 2026

.DISCUSSION...
A dry and stable atmospheric profile shown on the upper air
observation (RAOB) from this afternoon (22/00Z) is also reflected
on the latest satellite imageries and hourly observatoins
throughout the day. Model data ensembles show a strong and broad
high pressure system to the southwest migrating east, generating
and maintaining the moderate to fresh trades with higher gusts
throughout the forecast period. This high pressure is likely to
remain for the rest of the week into the new week as it continues
to hold a trough to the north of the area. Brief and passing
showers embedded within the wind flow will also move across the
islands from time to time. Expect fair weather conditions to
remain for this forecast period.

There is a low to no possibility of any tropical system to develop
within the area of responsibility for the next 7 days.

.Marine...
Fresh trade winds with higher gusts continue to maintain rough and
choppy conditions across the American Samoa coastal waters. Wind
driven wave heights peaking at around 10 feet are reported from the
PacIOOS buoy near Aunu`u. The breezy and rough conditions are
expected to remain for this forecast period. Model data show seas
slightly elevated by late Saturday into the new week. Thus, the
threat of strong and gusty trades, hazardous seas, dnagerous
surfs, and a moderate risk for rip currents in the surf zones for
all coastal waters.
