The Big Island is expected to experience the most severe impacts, including hurricane-force winds, heavy rainfall, and flooding. Maui County, Oʻahu, and Kauaʻi County will face tropical storm conditions, including strong winds and significant rainfall. Coastal areas are at risk of storm surge flooding, with water levels potentially rising 1 to 3 feet above ground. Life-threatening surf and rip currents are expected along east-facing and southern shores. The heavy rainfall may lead to flash flooding and mudslides, particularly in steep terrain. Residents and visitors should prepare for hazardous conditions and potential disruptions to travel and infrastructure.
