Area Forecast Discussion

.DISCUSSION...
The latest satellite imageries show the South Pacific Convergence
Zone (SPCZ) remaining south of the area. Although inching closer
to the territory, model data shows the ridge currently over the
area still dominating and will continue to hold dry conditions
through the weekend. Another feature showing on the satellite
imageries is a broad line of open cell cumuli clouds moving
westward, over the Swains Island area. This line of clouds to the
north and the SPCZ will have no impact in the American Samoa area
of respnsibility (AOR). Also supporting the dry conditions in the
AOR, model data shows a mid-level high pressure system remaining
over the area through the end of the forecast period. However,
model data shows a gentle to moderate easterly flow moving into
the area by late Thursday through at least Monday. This easterly
flow will likely bring embedded passing showers over the islands
during this time frame. Showers will be brief, and will not meet
flash flooding thresholds. Model data is also showing light and
variable winds returning by Monday night through the end of the
forecast period.

Thus, expect an isolated to scattered weather pattern with daily
high temperatures near and at the lower 90s, and light and
variable winds for tonight and Thursday. Winds will turn east at a
gentle breeze by late Thursday, increasing to moderate easterlies
by Friday through Sunday night. Light and variable winds will
return thereafter.

.Marine...
No significant swell is expected for this forecast period. Seas of
5 to 7 feet continues to remain across the coastal waters as
reported by the data from the PacIOOS buoys. Periods have slightly
lowered to around 10 to 12 seconds long compared to the last 16
to 24 hours. Model data is showing fluctuations of heights between
5 to 7 feet, and potentially peaking at 8 feet at times. This
pattern is likely due to a slight increase in easterly winds to a
more moderate breeze on Friday night through at least Sunday. These
conditions will likely remain for the rest of the forecast period.
Light and variable winds will return by the new week, and
therefore hold favorable conditions in the AOR.
