.Short term...
TONIGHT THROUGH SATURDAY NIGHT...High pressure to the south will
shift winds tonight to east flow. Satellite shows low level
convections to the southeast of the islands. Models suggest that
the low level convergence will remain southeast of islands in the
next few days before dissipating. With the high pressure to the
south, stable weather will continue to remain over the islands
through the weekend.

.Long term...
SUNDAY THROUGH THURSDAY...High pressure will continue to migrate
east. A ridge extending from the high pressure as it moves farther
east southeast will move near south of the islands on Tuesday
night, shifting winds to the northeast. As the ridge axis moves
across the islands on Wednesday, winds will become light and
variable through the midweek. Stable weather will persist
throughout the new week.

&&

.Marine...
Seas of 5 to 7 feet will persist through Sunday. Southwest swells
are expected to slightly elevate seas 6 to 8 feet on Sunday night
through Monday night as swells subside. No other significant
swells will impact the territory and coastal waters in the new
week.
