Area Forecast Discussion

.Discussion...
Latest satellite data shows a weak line of cumulus clouds just
south of the Islands. This indicates a weak trough that is
forecast to move over the territory on Monday as a high pressure
system builds behind it. However, due to the proximity of the
trough, expect numerous showers and light winds tonight. On
Monday, winds will slightly enhance as the high pressure pushes
the trough north and over the American Samoa region. The Islands
are forecast to lie at the edge of the high, with moisture
anchoring at the boundary through midweek. Hence, scattered to
numerous showers are expected for this duration.

The high pressure system will strengthen by Wednesday as it moves
east. Expect trade winds to return for the second half and showers
embedded within the trade wind flow.

.Marine...
Seas continue to subside since Saturday, as winds have diminished.
However, wave heights are currently within the 7 to 9-foot range,
as measure by the Aunu`u PacIOOS buoy. This observation maintains
seas within the advisory threshold (8 feet and higher). While
ocean conditions are forecast to subside throughout the week,
model data indicates a strong southeast swell moving into the area
on Monday. These swells are anticipated to persist throughout the
week, which means high surfs and strong rip currents will
persist.
