The ridge that brought fair weather conditions to the territory
continues to track east, moving farther away for the Samoa
Islands. To the north of the Samoa Islands, satellite data show a
weak trough that is expected to move closer to the islands
tonight. However, convection appears to be focused more north, so
there is a chance that rainfall associated with the trough could
miss the territory entirely. Nonetheless, numerous showers will
remain in the forecast tonight through Tuesday as model guidance
shows the trough dipping over the territory during this period. The
risk for flash flooding remains low, as the trough does not appear
to be particularly active.

As the trough moves westward Tuesday afternoon, a high pressure
system building near New Zealand is expected to build over the
islands. Scattered showers, along with east to southeast winds of
15 to 25 mph, will persist through the end of the forecast period
as the high pressure system strengthens.

The High Surf Advisory has been extended through the end of the
week. Although surf was expected to fall below 10 feet today as
winds diminished below 20 knots, the latest buoy data show seas
still lingering around 10 feet. Additionally, a strong south swell
is evident, with peak periods around 15 seconds. Model data shows
this swell lingering through the end of the week. With winds also
expected to increase to near 20 knots tonight and remain elevated
through the week, the Small Craft Advisory and High Surf Advisory
will likely persist into the weekend.
