.DISCUSSION...
No major threat is expected for this forecast period except for
passing showers from time to time and persistent warmer
temperatures for the next couple of days. These conditions are
likely associated with a mid-level high pressure system that
models project to linger over the area for the whole forecast
period. More daily high temperatures will likely peak at 90
degrees or more with dry conditions. Also, an easterly wind flow
will prevail all through Tuesday night before winds turn northeast
on Wednesday. Winds turning northeast is due to a low pressure
system developing near the Fiji Islands and is expected to migrate
southeast, passing south of the Samoa Islands as it pulls in
moisture from the northeast, as it continues to intensify. There
is no direct threat for American Samoa and its coastal waters
expected from this storm. However, a slight change in the system`s
location and strength can mean American Samoa and its waters will
have a direct impact from this sytem. These uncertainties are
expected to be higher after 3 days. Thus, this event will be
monitored as the week progresses and more data becomes available.

In the meantime, expect isolated to scattered showers with light
to moderate easterlies to persist for tonight through at least
Tuesday night.

.Marine...
Analysis of the latest ocean data shows no significant change
from the previous model projections. Seas of 5 to 7 feet will
remain for tonight and Friday before a large south swell reaches
shorelines on Friday night. This south swell will be accompanied
by periods peaking at 20 seconds long or more. The combination of
these two features usually mean surfs will likely be enhanced and
higher near shorelines, and stronger rip currents will be
generated. These would be the main threats for this time frame.
Model data continues to show seas subsiding to more favorable
conditions on Sunday and remain through the rest of the forecast
period. Thus, will continue to monitor conditions and issue alerts
as more data becomes available.
