.Short term...
A Flood Watch is cancelled as the trough that
produced widespread showers and strong winds overnight continues
to move south. Latest satellite data depicts moisture and
convection diminishing over the Samoa Island chain since this
morning. Wind observations of 20 to 30 mph seen in the wee hours
have also decreased to 10 to 15 mph this afternoon. Scattered
showers and variable winds are forecast for tonight until the
trough completely exits the region Monday.

.Long term...
East trade winds will gradually build in the area Monday afternoon
reaching up to 25 mph Tuesday through Thursday morning. Expect
scattered showers and breezy conditions for this timeframe.
However, trade winds are not expected to be as strong for the rest
of the forecast period.

.Marine...
A high surf warning was prompted early this morning as strong
winds moved in the area. Wave heights peaked at 15 feet when winds
were at its strongest (around 30 knots) before it made a downward
trend following the diminishing windspeeds later in the day. A
high surf advisory is now in effect, while a small craft advisory
remains in effect as current waves are around 10 feet. Latest
model data suggests seas will fall below advisory thresholds
Sunday through Monday. Calm seas will remain for this duration
before building up again to 7 to 9 feet Monday night with the
upcoming trade winds.
