Looking Ahead
Trade winds will continue over the islands, becoming strong and gusty by Friday and staying that way through the holiday weekend. Dry and stable conditions are expected to move over the islands from the east with mostly dry conditions continuing into Saturday. The airmass is forecast to gradually moisten from late Saturday through Monday, leading to increasing trade wind showers that will spread leeward on the smaller islands.
