Fair weather continues for the Samoa Islands. Low cumulus clouds
are evident, which suggests stable conditions. However, model data
shows an uptick in showers later tonight as a weak boundary
develops in the area. The territory is forecast to lie at the
edge of the ridge of high pressure extending from the southwest.
Being in this sweet spot allows for enhanced moisture that could
lead to passing showers and strong trade winds combined.

The ridge will hold breezy easterlies through the end of the week
as it continues to dominate. However, winds could reach advisory
levels by Thursday when the high strengthens during its eastward
track. Expect strong winds that could blow around unsecured
objects as this plays out. By the weekend, the high pressure will
exit the region. This will allow a trough to move in the area and
produce numerous showers and light winds.

Latest wave heights observed at the PacIOOS buoys remain below
advisory thresholds, around 5 to 7 feet. Expect calm ocean
conditions to continue through Monday until winds gradually build
by the afternoon. East winds up to 20 knots are possible at this
time, which will likely produce rough seas and prompt a small
craft advisory. Additionally, seas will continue to build through
the week as strong winds linger. Expect waves to peak at 9 feet
or higher by Friday.
