.Short term...

Satellite imagery has shown a mix of sun and clouds throughout the
morning and early afternoon hours. A ridge of high pressure
continues to remain over the American Samoa islands. This is
responsible for generating east/southeasterly trades over the
islands.

The weather is not anticipated to change much through the weekend.
If passing showers occur, it would be in the passing form and is
not expected to be heavy. East/southeasterly trades may reach up
to around 20 mph at times. Otherwise, severe weather is not
forecast during this time.

.Long term...

The slow moving weather pattern continues for early to the middle
of next week. We will monitor the equatorial ridge to the north to
see if it will push the trough located to the north of Swains over
the American Samoa islands. However, the aforemention ridge to
the south is forecast to be to strong enough to keep the trough to
the north of the islands to maintain breezy tradewinds with the
possibility of passing showers.

Therefore, rain is forecast to be below average for the next 7
days.

.Marine...

Data from the PacIOOS buoy to the east of Aunu`u shows seas around
9 feet with no significant swell moving through the American Samoa
coastal waters. These rough wind driven waves are forecast to
continue for the next 5 days as a ridge of high pressure remains
nearly stationary over the region.

The Small Craft Advisory remains in effect during this time. The
High Surf Advisory will also remain in effect for the eastern and
southern shores, but no major coastal erosion is anticipated.
