The Big Island is expected to experience significant impacts, including heavy rainfall of up to 35 inches in some areas, widespread flooding, and potential landslides. Coastal areas may face storm surges of up to 3 feet, leading to beach erosion and impassable roads. Wind gusts could reach catastrophic levels, causing structural damage, snapped trees, and widespread power outages. The NWS Honolulu has urged residents to prepare for severe conditions, as the storm's effects could render some locations uninhabitable for months.
