.Discussion...
Latest satellite data show fair weather over American Samoa.
However, to the west over Upolu and Savaii, and east of Manu`a,
thunderstorms are evident. Latest model data suggests an uptick in
showers tonight as these thunderstorms build across the Samoa
Island chain. By Wednesday, the thunderstorms will dissipate as
the sun rises. Expect showers to decrease by this time, and
stable weather will hold through Thursday. Winds are expected to
be light and variable throughout the week.

.Long term...
A weak trough is forecast to develop in the area Thursday night.
This feature will bring numerous showers and possible thunderstorms
through Friday morning. By Friday afternoon, a gentle breeze and
fair weather will persist through Monday.

.Marine...
Calm seas are currently observed, as winds are light and
variable. Although a south swell is reported at the King-Poloa
PacIOOS buoy, it doesn`t appear to be significant enough to
produce hazardous surfs and/or rip currents. Smooth ocean
conditions is forecast to remain through Thursday. However,
showers developing in the area tonight may produce rough seas
at times. Additionally, another set of swells from the south may
elevate seas and surfs Thursday afternoon. This set is expected to
be stronger than the one we are experiencing today.
