HONOLULU (HawaiiNewsNow) – Forecasters are calling for an increase in showers as we head into a busy Halloween weekend.
An upper level low is moving closer to our islands from the east, causing our atmosphere to become increasingly unstable. Generally speaking it will enhance the tradewind showers starting tonight, making them more frequent and perhaps a bit heavier. Most of the moisture will fall windward and mauka, but leeward areas will also see some rainfall.
Since the upper level disturbance will come closest to the Big Island, the Hamakua Coast could see the wettest weather. Showers there could be heavy on Saturday with a slight chance of thunderstorms. Windward Maui may also see some heavy showers.
Looking ahead to Halloween Monday, leeward areas should stay mostly dry with intermittent windward and mauka showers.
