.Short term...
TONIGHT THROUGH SUNDAY NIGHT...Satellite shows an active trough
over Fiji and a high pressure to the southeast of the Samoan
islands. A col is situated over the islands holding light flow.
The high pressure to the southeast will slightly intensify and
increase winds to gentle flow tonight from the east. Moist
easterly flow continue to hold numerous showers tonight before
reducing to scattered on Saturday. A low level convergence is
expected to again increase showers over the islands on Sunday
before it gradually dissipate on late Sunday night.

.Long term...
MONDAY THROUGH FRIDAY...With the ridge to the south, stable
weather and gentle winds will persist at the start of the new
week. As the ridge shifts farther southwest, winds will diminish
to light flow on Tuesday. High pressure will migrate southeast on
Tuesday night. This will hold light winds through the end of the
week. Stable weather will also persist.

.Marine...
South swells continue to elevate seas to rough conditions tonight
through Monday night. Another set of swells from the southeast is
expected to move across the islands on Sunday night. This will
continue to hold rough seas over the islands. As swells subside
late Monday night, seas will drop 6 to 8 feet before reaching 5 to
7 feet on Tuesday morning. Another set of swells from the
southwest will pass across the islands on Wednesday night. These
swells are expected to elevate seas above advisory thresholds.
Hence, seas will remain 5 to 7 feet through the rest of the week.
