The primary risks associated with Tropical Depression Two-C include heavy rainfall, flash flooding, and mudslides, particularly in the windward areas of the Big Island. The storm is expected to bring tropical downpours that could exacerbate existing power outages, with over 10,000 residents already without electricity. Coastal areas may face dangerous surf conditions and storm surges, further increasing the flood threat. The potential for widespread impacts underscores the need for vigilance, especially as the storm's exact path remains uncertain.
