The smell of death hung over parts of Great Abaco Island in the northern Bahamas on Friday, as relief workers sifted through the debris of shattered homes and buildings in a search expected to dramatically drive up the death toll from Hurricane Dorian.
Dorian, the most powerful hurricane ever to hit the Bahamas, swept through the Abaco Islands and Grand Bahama Island earlier this week, levelling entire neighbourhoods and knocking out key infrastructure, including airport landing strips and a hospital.
The UK government said it had set aside an initial £1.5 million (Dh6.7 million) for its response to the disaster.
The government said the money would be used to fund supplies already being delivered to the rescue effort and support the Caribbean Disaster Emergency Management Agency.
UK international development secretary Alok Sharma said: “DFID expert are working as part of the cross-government team alongside local authorities, the British military and international partners to urgently get life-saving assistance to the people of the Bahamas.”
Hundreds, if not thousands of people are still missing in the country, which has a population of about 400,000.
Officials say the death toll, which stands at 30, is likely to shoot up as more bodies are discovered in the ruins and floodwaters left behind by the storm.
"You smell the decomposing bodies as you walk through Marsh Harbour," said Sandra Sweeting, 37, in an interview amid the wreckage on Great Abaco.
"It's everywhere. There are a lot of people who aren't going to make it off this island."
Some locals called the government's initial official death toll a tragic underestimate.
"I work part-time in a funeral home. I know what death smells like," said Anthony Thompson, 27.
"There must be hundreds. Hundreds."
Chaotic conditions around the islands were interfering with flights and boats, hampering relief efforts.
The medical chief of staff of Bahamas' only functioning public hospital said the death toll would be "staggering," and two refrigerated, 40-foot trucks would be needed to hold the bodies that were expected to be found.
"We’ve ordered lots of body bags," Dr Caroline Burnett-Garraway said in an interview at Princess Margaret Hospital in Nassau, the country's capital.
She added that processing the dead would take weeks.
Those injured by the storm, a Category 5 hurricane on the five-step Saffir-Simpson scale of intensity, were being treated for fractures, head injuries, deep lacerations, skin rashes and dehydration.
Survivors are also dealing with the emotional trauma triggered by the horrors of the preceding days.
Near an area called The Mudd at Marsh Harbour, the commercial hub of Great Abaco, a Reuters photographer described a devastating scene, with most houses levelled, a man lying dead near a main street and dead dogs in water. Some residents were leaving the area with meagre possessions, while others were determined to remain.
Medical facilities in Grand Bahama, the Abacos and Nassau were "coping, so far" with the injured, said Aubynette Rolle of the Bahamas Public Hospitals Authority.
Ms Rolle said urgent care was being provided on the hurricane-hit islands while makeshift clinics were dealing with non-urgent casualties.
A triage system has been set up at a Nassau airport to direct more critical patients to Princess Margaret Hospital.
Shelter material for hundreds of people as well as hygiene kits including basic items like soap were unloaded from the British ship RFA Mounts Bay and distributed in Marsh Harbour, the United Kingdom's Department for International Development said on Friday.
British forces are also distributing water from supplies aboard the ship, which has a system to turn sea water into drinking water.
The US Coast Guard, working with the National Emergency Management Agency in the Bahamas, has rescued 295 people since Dorian began, the US embassy in Nassau tweeted.
The embassy also announced that 32 tons of emergency supplies from USAID had arrived in the Bahamas.
Relief groups are focusing on getting doctors, nurses and medical supplies into the hardest-hit areas and helping survivors get food and safe drinking water.
The risk of outbreaks of diarrhoea and waterborne diseases is high because drinking water may be contaminated with sewage, according to the Pan American Health Organization, which described the situation for some people on Abaco as "desperate."
The United Nations estimated 70,000 people were in immediate need of food, water and shelter on the islands, where looting of liquor stores and supermarkets has been reported.
Wendy Hawkes, whose home on Abaco was largely destroyed, described seeing neighbours standing outside their front doors with shotguns to ward off looters.
The relief effort faces formidable logistical challenges because of the widespread destruction of Dorian, which hovered over the Bahamas for nearly two days with torrential rains and fierce winds that whipped up storm surges as high as 5.5 metres.
The storm made landfall on the Outer Banks of North Carolina on Friday with winds of 90 miles per hour.
The UN World Food Programme is airlifting storage units, generators, prefab offices, and satellite equipment as well as 8 tons of ready-to-eat meals.
