The Big Island faces significant risks from Hurricane Nolo's outer bands, including flash flooding, destructive waves, and gusty winds. Coastal erosion and storm surge are threatening low-lying areas, while volcanic tephra from Kilauea could contaminate water catchment systems and create slick road surfaces. Emergency officials warn that even though the storm's center remains offshore, its effects are widespread. Vulnerable populations in non-reinforced structures are particularly at risk, and recovery efforts are strained due to previous disasters. Residents should remain cautious and avoid exposed coastal areas and steep drainage basins.
