The Big Island and parts of Maui County are at risk of severe impacts, including up to 35 inches of rain on the Big Island and up to 20 inches on Maui, which could lead to catastrophic flash flooding and mudslides. Winds capable of causing tree damage and power outages are expected, particularly in the southern parts of the Big Island, with hurricane-force winds possible depending on the storm's track. Coastal flooding, high surf, and a storm surge of 1-3 feet are also likely. These conditions could exacerbate damage in areas still recovering from previous storms this season.
