Latest satellite imagery shows remnants of clouds associated with
the trough to the north moving across the Samoa Island chain.
Although these clouds are moving into a dry and stable
environment, it could slightly enhance moisture for the territory.
This is further supported by the latest upper air sounding (8/15
00Z), which depicts a relatively dry profile and moist surface
layer up to 800 mb. Expect isolated showers to become scattered
tonight and remain through Tuesday.

East winds of 10 to 15 mph will continue through tonight before
diminishing to a gentle breeze Saturday afternoon. Light and
variable winds are then expected through Tuesday before tradewinds
return thereafter. However, ahead of the trades another frontal
boundary could develop, but our confidence in this occurring is
low at this time.

The High Surf and Small Craft advisories have been cancelled as
wave heights have subsided to around 6 to 7 feet. Seas are
expected to continue trending lower into the new week as winds
weaken to below 10 knots.

A south swell remains evident in the latest PacIOOS buoy
observations, with peak periods near 13 seconds. This swell is
expected to gradually subside through Sunday. Another south swell
is then forecast to move into the area Monday, coinciding with the
return of strengthening tradewinds. The combination of the
incoming swell and increasing winds may lead to potentially
hazardous marine conditions next week.
