155 PM SST Sun Nov 18 2018

.Short term...
TONIGHT THROUGH TUESDAY NIGHT...The surface trough that brought
showers over the islands early this morning has moved north. This
trough will dissipate as a strong high pressure system to the
east builds over the islands. RAOB from this afternoon depicts a
conditional unstable profile. Hence, scattered showers will remain
across the islands tonight through Monday. However, a moist
easterly flow will hold scattered showers across the islands
through Monday night. With the surface trough to the south, winds
will remain light and variable throughout the short term.


.Long term...
WEDNESDAY THROUGH SUNDAY...Easterly flow will slightly strengthen
on Tuesday bringing gentle east winds. A ridge will build south on
Wednesday and hence shifting winds to breezy trades across the
islands. Showers will remain isolated throughout the new week.

&&

Marine...Wave heights of 5 to 7 feet are currently observed at
the PacIOOS Aunuu buoy, and are forecast to remain at this level
until Tuesday. Hence, expecting seas to diminish to 4 to 6 feet by
Tuesday in accordance with the PacIOOS and WW3 models. No
significant swells will affect the islands throughout this
forecast period.


.PPG WATCHES/WARNINGS/ADVISORIES...
None.
