Nearly 2 inches of rain were recorded overnight at WFO American
Samoa due to the trough mentioned in the previous forecast.
However, other locations across Tutuila and Aunu`u received no
more than about half an inch. Expect widespread showers to
continue through tonight before diminishing overnight as
convection associated with the trough moves southeast. Model
guidance weakens the trough over the weekend, though it is
expected to linger in the area through next weekend.

Light and variable winds will persist through Sunday night before
shifting predominantly east to southeast on Monday as a high
pressure system builds from the southwest. Breezy conditions will
follow and continue through the end of the week, while remnants
from the trough could enhance moisture in the area at times.

The Small Craft Advisory and High Surf Advisory have been
canceled. Wave heights observed at the PacIOOS buoy have fallen
below the advisory criteria of 8 feet and is expected to remain
below advisory levels through Monday. Around that time, another
south swell is forecast to move into the area, and winds are also
expected to strengthen, returning high surf, strong rip currents,
and rough ocean conditions through midweek.
