USAID Director Mark Green toured Abaco Island for himself, telling reporters, some areas appear fine, while others look like a nuclear bomb went off.
Bahamian officials are still pulling bodies from the wreckage across the island and acknowledge that the current official death toll of 43 is likely to rise.
Some 70,000 people are in need of food and shelter, according to the United Nations' World Food Programme's estimate. Interviews with evacuees this week highlighted the extent of Dorian's destruction. Survivors avoided death, but have lost homes, jobs and hospitals.
"Home is more than four walls and a roof - it's the neighborhood where people live, their friends and neighbors, their livelihoods, comfort, and security for the future. Losing all these things at once is heartbreaking," said Jenelle Eli, a spokeswoman for the Red Cross, which is helping with the relief. "People are concerned about their next step, but also how they'll earn an income and what their lives will look like in the future."
