A high pressure system to the south continues to bring cool, dry
air over the territory. The trough that brought showers last week
finally shifted farther north today, as seen in the latest
satellite imagery. Expect isolated showers and cool weather to
continue through Monday. However, as the high pressure
strengthens, southeast winds are expected to increase to 15 to 25
mph by Monday afternoon. Model guidance suggests the trade winds
will persist through Tuesday while gradually shifting eastward.

As the high pressure system moves farther east Tuesday night, a
trough to the north will shift toward the Samoa Island chain.
Expect an uptick in showers for midweek, along with light and
variable winds. However, the potential for flash flooding from
this trough remains low at this time. A wet pattern is expected to
persist through the end of the week.

Wave heights have subsided to 6 to 8 feet this morning as the
south swell continues to diminish. This prompted the cancellation
of the High Surf Advisory earlier today. However, a Small Craft
Advisory remains in effect as winds are forecast to build up to 20
knots on Monday. Expect choppy ocean conditions through Tuesday
before calmer seas take over by midweek.
