Dangerous flooding is impacting Hawaii's Oahu island, prompting more than 230 rescues, "catastrophic" damage as major rains pummel the area for the second significant rain event in a week.

Owner Dole Food Company Hawaii said in a statement, “These thresholds are intentionally conservative and based on the time required to safely evacuate downstream areas; they do not reflect a loss of structural integrity.

Power will not be restored to thousands of North Shore customers until it is safe to do so, following catastrophic flooding and ongoing evacuation orders, according to Hawaiian Electric.

Authorities issued urgent evacuation orders on Oahu’s North Shore after a potential failure at Wahiawa Dam threatened life-threatening flooding. Residents in Haleiwa and Waialua were told to evacuate immediately as flooding was reported along nearby streams.

Honolulu city officials said this morning that water levels remain consistent at Wahiawa Dam so the evacuation notice for the area has been lifted.
