.DISCUSSION...
Fair weather patterns continue to remain over the islands as a
high pressure system to the southeast continues to migrate further
east. This pattern is expected to remain over the area through at
least midweed; isolated to scattered showers with a gentle to
moderate east-southeast breeze.

Model data show the winds increasing to a fresh south-southeast
breeze on Tuesday night, peaking at near gale force winds by
Thursday through Friday. This increased wind pattern is generated
by another strong high pressure system from the southwest moving
eastward. As the latter high pressure system move eastward,
bonadary layers/lines will move across the islands, increasing the
potential for showers from time to time throughout this time
period. Also shown on the model solutions is a trough to the
north, migrating southward starting Thursday night and increasing
flash flooding potential through the weekend. Therefore, expect
numerous to widespread showers with gusty winds for the second
half of the new week.

.Marine...
Favorable ocean conditions remain over the area as east-southeast
winds decrease to a gentle to moderate breeze. These conditions
are expected to continue through at least Tuesday. By Tuesday
night, a large south-southwest swell will reach American Samoa
shorelines, building seas and surfs to advisory thresholds, and
possibly reaching warning levels by the end of the forecast
period. The hazardous seas are likely generated by the strong to
near gale force south to southeast winds expected over the area at
this time frame. In the meantime, the advisory for small crafts
is now cancelled.
