The Hawaiian Islands, particularly the Big Island and Maui, are at risk of experiencing severe weather conditions, including heavy rainfall of 5 to 10 inches, with localized amounts up to 20 inches in windward areas. Flash flooding and rapidly rising streams are possible, along with damaging winds and high surf. Oahu may also face gusty winds and an increased risk of wildfires ahead of the storm. Residents are advised to prepare for potential disruptions, including power outages and hazardous travel conditions. Coastal areas may experience dangerous surf and flooding, especially along east-facing shores.
