Frequent showers are expected for windward and mauka areas tonight. Leeward spots are forecasted to be mostly cloudy with scattered showers in the evening, then isolated showers after midnight. Trade winds are forecasted around 15 mph. Low temperatures from 67° to 72° are expected.
Looking Ahead
Locally breezy trade winds are expected over the islands through next week.
