Looking Ahead
Low clouds and modest shower activity will favor windward slopes, while high clouds are expected to increase over parts of the island chain. Easterly trade winds are forecasted to strengthen this weekend. Showers will be focused across windward areas, though pockets of moisture in the trade wind flow will produce some leeward rainfall at times. One such area of showers is expected to pass through late Saturday afternoon and Saturday night.
