The worst flooding to hit Hawaii in two decades swept homes off their foundations, floated cars out of driveways and left floors, walls and counters covered in thick, reddish volcanic mud. Crews continued to assess the destruction Monday, but new downpours set off a fresh round of flooding on Oahu’s south side even as residents on the island’s North Shore cleaned up and assessed the destruction from last week's deluge. Authorities said hundreds of homes were damaged, along with some schools and a hospital. No deaths have been reported, but more than 230 people had to be rescued. Gov. Josh Green said the cost of the storm could top $1 billion.

More than 2,000 people remain without power Sunday afternoon because of historic flooding in Hawaii. Heavy rains fell on soil already saturated by downpours from a winter storm a week ago. Raging waters lifted homes and cars and is expected to cause nearly $1 billion in damages. The storm prompted evaluation orders for 5,500 people north of Honolulu, though they were later lifted, and more than 200 people were rescued from the rising waters.

More than 200 people were rescued Friday as heavy rains pummeled the Hawaiian island of Oahu and triggered the worst flooding the island has in 20 years. Hawaii Gov. Josh Green says the damage could top $1 billion. Muddy floodwaters from severe rains have inundated communities and prompted evacuation orders for more than 5,500 people in towns north of Honolulu. Officials are warning about the possible failure of a 120-year-old dam. Officials have been watching dam levels since a storm last week dumped heavy rain across the state, which led to catastrophic flooding that washed away roads and homes.

Thousands of people in towns north of Honolulu have been told to evacuate their homes as flooding intensifies.
