More than 230 people have been rescued as flash floods hit the Hawaiian island of Oahu, triggering fears that a dam could fail. The flooding is the worst the island has seen in 20 years, with Governor Josh Green warning that damage could exceed $1bn.
Water levels at the dam have receded slightly but remain just 6ft (1.8 metres) below capacity. Authorities have issued evacuation orders for about 5,500 people. No deaths have been reported, but around 10 people were taken to hospital with hypothermia.
Honolulu Mayor Rick Blangiardi described the damage as catastrophic, with dozens or hundreds of homes affected. Officials are struggling to fully assess the destruction, with rescue efforts hampered by drones flown by members of the public.
Parts of Oahu received 8 to 12 inches (20-30cm) of rain overnight, adding to saturated ground from last week's storm. The National Weather Service has issued flood watches for most of the state, with flash flood warnings for northern areas.
