.Short term...

More sun than clouds remained over the American Samoa islands
throughout the day today as a gale remains to the south of the
region. However, satellite imagery shows a cold front to the
southwest moving towards the territory. Showers are expected
overnight, but not heavy enough to cause flash flooding. The front
is forecast to quickly move through the region and to move away
by Saturday afternoon. Current winds from the west of 10 to 15
mph are forecast to become southerly by Sunday.

Lower than usual temperatures are forecast the weekend and into
early next week. More sun than clouds are expected on Sunday and
Monday with only a slight risk of a passing shower.

.Long term...

Winds are forecast to become southeasterly by Monday night and
may increase to near Wind Advisory levels through late next week.
If showers occur, it will be in the passing form. Heavy rainfall
is not expected throughout this time. Cooler than average
temperatures will continue through at least the middle of the
week.

.Marine...

The latest information from both PacIOOS buoys to the west and
east of Tutuila shows seas have eased to below 6 feet along the
American Samoa coastal waters. However, we expect seas to slowly
build throughout the weekend as a gale well to the south of
American Samoa is to produce southerly swell that is forecast to
enter the region. Small Craft and High Surf Advisory conditions
are expected to start as early as Saturday afternoon. We will
monitor sea conditions throughout the weekend as surf along the
southern shores will be at, or at least near, the High Surf
Warning criteria on Sunday through early next week. We are also
monitoring the potential for up to a near gale force
east/southeasterly breeze from Monday night through the middle of
the upcoming week.
