Looking Ahead

High pressure north of the state will provide for a typical trade wind weather pattern across the area through Tuesday. Clouds and passing showers will favor windward and mauka areas with just a few brief light showers expected over select leeward locations. For the remainder of the week and on into the weekend, our weather pattern will be highly dependent on the track and intensity of Hurricane Lane.
