    Looking Ahead

    A weakening trade wind pattern will prevail through the holiday weekend, with clouds and passing showers favoring windward and mountain areas. An increase in trade wind showers is expected on Kauai and Oahu tonight and Sunday. Meanwhile, afternoon sea breezes will bring a few clouds to leeward areas, especially Sunday and Monday. Increased moisture combined with strengthening trade winds may cause more widespread windward showers Monday night and Tuesday. Hurricane Norman is forecast to move close to the islands around the middle to end of the week, but it is too early to determine what impact Norman will have on Hawaiian weather.
