Persistence in the forecast as the current trade wind pattern
generally continues over the next several days. Windward shower
activity will encroach the islands due to prevailing easterlies
leading to isolated/scattered instances of light to moderate
rainfall across the eastern half of the islands. Trade winds may
weaken some by the middle of next week, but the overall pattern
will continue to favor just light diurnally driven showers, with
relatively calm conditions otherwise.
