Looking Ahead
Trade winds are on the decline as a front approaches and will shift out of the southeast. Moderate rainfall and stiff north winds are expected as the front pushes down the island chain. Expected arrival time for the Big Island is Tuesday and Tuesday night. By the time the front reaches Hawaii County it will likely be disorganized and mainly composed of frontal remnants. Ahead of the front winds will weaken and a diurnal land / sea breeze weather pattern will set up. Behind the front, cool and dry conditions are forecasted.
