.Short term...
TONIGHT THROUGH SUNDAY NIGHT...Invest 95P, located approximately
940 miles northeast of Tutuila, remains nearly stationary while
gradually strengthening. Meanwhile, a high pressure to the far
southeast will maintain breezy trades and scattered showers across
the islands tonight. Stable weather will move across the islands
on Saturday through Sunday. This will decrease showers to isolated
before slightly increase to scattered on Sunday night.

.Long term...
MONDAY THROUGH FRIDAY...Invest 95P is expected to strengthen
further and begin tracking westward on Sunday. Strong vertical
wind shear over the main Samoan island chain will likely inhibit
further development as the system approaches the region. By
Thursday night, as 95P moves closer to Swains island, strong winds
and increased moisture associated with the system will maintain
numerous to widespread showers across the area through the latter
part of the week.

&&

.Marine...
Seas of 7 to 9 feet will persist tonight through Sunday. As trades
increase to strong flow, seas will build 9 to 12 feet on Sunday
night. These hazardous seas are expected to continue through the
rest of the new week.
