Area Forecast Discussion

.DISCUSSION...
On the latest satellite imageries, the easterly wind flow
continues to move open cell cumuli clouds across the territory.
This feature will mainly bring brief passing showers across the
islands for the forecast period. A mid-level high pressure system
will linger over the area as it suppresses any major cloud growth
and also limiting any flash flooding conditions. The moderate to
fresh easterlies will remain through midweek, turning southeast
on Thursday through the new week. The high pressure system to the
south also generating the easterlies will continue to migrate
eastward and exit the region by midweek. Another high pressure
system to the southwest will also migrate eastward as it generates
moderate to fresh trades by the weekend through the new week.
Showers embedded within the wind flow will move across the islands
throughout the forecast period.

Therefore, expect isolated to scattered showers with moderate to
fresh easterlies for tonight through the midweek, and winds
turning southeast on Thursday through the new week. Drier and
cooler temperatures are also expected for this time frame.

.Marine...
Data from the PacIOOs buoy near Aunu`u show wave heights around 7
to 9 feet with periods less than 10 seconds. These are mainly
wind-driven waves generated by the moderate to fresh easterlies
moving across the territory. This short-lived phenomena is only
expected for rest of today through tonight. Hence, the advisory
for small crafts will remain in effect through Tuesday.
Additionally, model data is showing seas gradually subsiding to
more favorable conditions with heights remaining below advisory
thresholds. This trend will continue throughout the week, and no
other significant swell is expected for this forecast period.
