The Big Island faces significant risks, including widespread power outages, communication failures, and potential destruction of roads and buildings. Life-threatening flooding and mudslides are expected due to heavy rainfall, particularly in higher elevations. Maui and other islands may also experience dangerous flooding and mudslides, though impacts are forecasted to be less severe. Residents are urged to prepare for hazardous conditions as the storm approaches. The cumulative damage from this year's disasters has already reached $686 million, highlighting the vulnerability of the region.
