...Tropical Storm Ana slowly moving away...

Wind, waves, and rainfall associated with Ana continue to diminish
as the cyclone tracks northwestward away from the state through
the end of the week. For additional and updated
information/forecasts on 'Ana', please refer to the Central
Pacific Hurricane Center and your local National Weather Service
office.

In the wake of Ana, weak high pressure north of the islands will
modulate slightly in intensity and position, but otherwise provide
for weak to moderate trades through the weekend and into the
middle of next week, along with scattered mainly windward showers.

large-scale wise, current model guidance shows strong flow
continuing across the north central pacific that leads to growing
spread and uncertainty with a prevailing large-scale trough
continuing over the eastern Pacific that has modest influences
from Ana and a synoptic system crossing the southwest Pacific.
Impacts could be differing strengths of the low level winds across
Hawaii perhaps by this weekend if the systems interact differently
from the model consensus that has average if not slightly below
average confidence associated with it at this time.
