Looking Ahead 

Friday a strong cold front is expected to sweep down the island chain. Gusty southwest winds will increase Friday afternoon ahead of the front with heavy rain, thunderstorms and potentially damaging winds along the front. The front is expected to pass over Kauai Friday evening, Oahu and Maui county Friday night, and the Big Island Saturday morning. The front is expected to move quickly, at about 25 mph, so the threat for flooding is greatly reduced but can’t be ruled out. The greatest threat for damage comes from the winds. Cool and dry weather is expected after the front passes.
