Looking Ahead

ARTICLE CONTINUES BELOW AD

Trade wind weather is forecast into the weekend with showers for our usual windward and mauka spots. Enhanced trade showers are forecast through Wednesday. Hurricane Fernanda continues to move northwest and is forecast to weaken over the next couple of days. It’s still too soon to know what affect Fernanda will have on island weather early next week. On the current path, we could either see tropical moisture move over the state or if the system passes far north, it could cut off our trade winds and bring muggy weather.
