Looking Ahead
A moderately strong high pressure system passing north of the islands will bring a boost in the trade winds through Wednesday, resulting in locally strong speeds. As the high moves to northeast of the islands during the second half of the week, the trades will weaken to light to moderate speeds Friday. Winds are expected to become light and variable over the upcoming weekend. Under this trade wind flow, expect some brief passing showers, favoring the windward and mountain areas. An increase in moisture is expected Wednesday night and Thursday, and this moisture may linger into the weekend, fueling increased showers.
