First Alert Forecast: Wet weather, life-threatening surf expected as cold front approaches state
HONOLULU (HawaiiNewsNow) - A line of showers associated with a cold front nearing Kauai this evening will continue eastward overnight, then stall and diminish around Oahu and Molokai Wednesday through Thursday.
Lingering residual moisture combined with an upper disturbance over the region will keep rainfall chances around through the second half of the week.
Additional instability from the cold pool aloft may lead to a few heavier showers or even isolated thunderstorms, particularly from Oahu to the Big Island Wednesday night through Thursday.
With these factors in mind, the Hawaii News Now weather team has declared a low-grade FIRST ALERT WEATHER DAY starting Wednesday afternoon into Thursday as we track a front for Oahu and parts of Maui County bringing disruptive weather at times.
