.Shore term...
[TONIGHT THROUGH FRIDAY]...A ridge of high pressure over the
Islands continues to push showers westward. This feature currently
drives an easterly breeze around 10 to 20 mph. Expect trade winds
and scattered showers to persist through Friday until the ridge
weakens in the area Friday afternoon. Although fair weather
usually accompanies a high pressure system, satellite data shows
showers embedded within the trade wind flow. This pattern suggests
a slightly unstable atmosphere, which will bring passing showers
through Friday.

.Long term...
[FRIDAY NIGHT THROUGH WEDNESDAY]...A mid-level low pressure
system will continue instability in the area through the weekend.
Hence, scattered to numerous showers is possible for this time,
though flash flooding conditions is unlikely. Additionally, no
tropical cyclone development is expected for the rest of the
forecast period.

.Marine...
A small craft advisory is cancelled as wave heights and winds have
fallen below advisory levels (8 feet). Although wave heights have
subsided, winds up to 15 knots may hold textured seas through the
new week. No significant swells or winds are expected for the
forecast period.
