.Short term...

A mix of sun and clouds remained over American Samoa once again
today as a ridge of high pressure is over the region. However,
this high is currently weakening, which is allowing a trough from
the north to move towards the territory. By tonight, the trough
is expected to reach the islands. This will increase the risk of
rain from scattered to numerous to widespread (80% chance). This
trough is forecast to remain over the region through at least
Monday night before slowly moving to the southeast by mid-week.
Rain is likely during this time. We will monitor the movement of
the trough for Tuesday. Right now, the trough will likely linger
throughout the day. Therefore, numerous showers remain in the
forecast.

.Long term...

By mid-week, the aforementioned trough is to move away from the
region. A ridge from the southw, which is to create below average
rainfall. Southeasterly trades are expected to slowly increase
throughout the week and to reach up to 20 mph by the upcoming
weekend. More sun than clouds are anticipated throughout the days
and temperature are to be slightly above average.

.Marine...

Rough seas continue throughout the American Samoa coastal waters
as a southeasterly swell continues to elevate seas up to 10 feet.
Conditions are forecast slowly ease, but still to remain in the
Small Craft Advisory criteria through at least Tuesday. Winds are
also expected to decrease to a gentle northerly breeze by Monday
and a gentle northwesterly breeze on Tuesday. The high surf
advisory is to remain in effect through Wednesday. Even though
projected surf heights at 12 feet today are to ease to around 10
feet on Monday, a long period southerly swell is begin moving
through the coastal waters on Tuesday. This will elevate surf
along the southerly shores throughout the day.
