SYDNEY (Reuters) – Tens of thousands of Fijians remain homeless and living in evacuation shelters in the aftermath of a devastating cyclone at the weekend, officials said on Thursday, as aid began trickling in to the outer reaches of the South Pacific archipelago.

The death toll from Cyclone Winston, the worst storm ever recorded in the southern hemisphere, remained at 42 but officials at Fiji’s National Disaster Management Office fear that figure will rise.

Officials from the disaster agency estimate that 35,000 people are sheltering in evacuation centers, some of which are damaged and running short of food and other supplies. Some 900,000 people live in the archipelago of more than 300 islands

International aid agencies said supplies were being delivered but the scale of the damage to infrastructure, particularly jetties and communications equipment, was making it hard to reach remote communities where help was most needed.

CARE Australia spokesman Dylan Quinnell said there had still been no contact with some remote communities, including one at Yasawa on the northwest coast of Fiji’s largest island, Viti Levu, since the cyclone made landfall on Saturday. Others had been reached using radios dropped by the New Zealand air force.

Alice Clements, a UNICEF aid worker, told Reuters by phone from Nadi, Fiji’s main tourism hub, that some communities had been totally destroyed but that rebuilding had already begun.

“People are going out during the day to recover what they can, it’s not like they’re sitting in the shelters helpless, they are salvaging what they can and dusting themselves off,” Clements said.

Ahmad Sami, the acting head of the International Red Cross in the Pacific, said providing shelter and water remained immediate priorities.

“Volunteers on the ground are saying the destruction is like nothing which they have ever seen before,” Sami said.

“Houses have collapsed, communications are still down, power transmission is down, wharves are still not accessible and roads and highways have been damaged,” he said.

Joseph Hing, another UNICEF worker, landed on the worst-hit island of Koro on Tuesday and said it “looked like someone took a torch and just burnt from one side to the other”.

“As we sailed closer, we started to smell the dead carcasses of livestock that were floating past the ships. When we smelt those, we knew that this disaster was really, really bad,” he said in a statement.

Aid workers have warned of potential outbreaks of the Zika and Dengue viruses, both carried by mosquitoes that could breed in the stagnant water left by the storm.

SYDNEY (Reuters) – Fiji began a massive cleanup on Monday after one of the most powerful storms recorded in the southern hemisphere tore through the Pacific island nation, killing 21 people, flattening remote villages and cutting off communications.

Aid agencies warned of a widespread health crisis, particularly in low-lying areas where thousands of Fiji’s 900,000 people live in tin shacks, after crops were wiped out and fresh water supplies blocked.

The Fiji Broadcasting Corp, quoting the country’s National Disaster Management Office, said 21 people had died and four were still missing at sea.

Almost 8,000 people remained hunkered down in hundreds of evacuation centers across Fiji where they had headed before tropical cyclone Winston hit late on Saturday with winds of up to 200 mph.

“The death toll from Cyclone Winston continues to rise and reports of widespread damage are coming in from across Fiji,” said New Zealand Foreign Minister Murray McCully. “It is clear that Fiji faces a major cleanup and recovery operation.”

McCully said a New Zealand Defense Force C-130 would leave for the Fijian capital, Suva, later on Monday with relief supplies and an emergency response team.

The majority of the fatalities were along the western coast and were caused mainly by flying debris and drowning in storm surges, authorities said.

A 36-hour curfew was lifted early on Monday, allowing the Fijian military to ramp up efforts to reach the more remote parts of the archipelago of about 300 islands.

“The Fijians are desperately trying to repair severed lines of communication, but they hold grave fears that the news waiting for them will be dire,” said Raijeli Nicole, Pacific regional director of aid group Oxfam.

“Given the intensity of the storm and the images we have seen so far, there are strong concerns that the death toll won’t stop climbing today and that hundreds of people will have seen their homes and livelihoods completely destroyed.”

Aerial footage of outlying islands taken by the Royal New Zealand Air Force, and posted on the Fiji government’s official website, showed whole villages flattened and flooded.

Aid agencies were told at a meeting of Fiji’s National Emergency Operations Center on Monday of potential “catastrophic” damage to Koro Island, Fiji’s seventh-largest island.

“The aerial survey suggested the runway looks OK so they are going to land on this later this afternoon with emergency personal and some supplies,” said Anna Cowley of CARE Australia.

Fiji also reopened its main airport at Nadi.

Food and water supplies are a growing concern, even for areas such as Suva that did not suffer as much damage as the more remote regions.

The Consumer Council of Fiji has urged traders not to sell food and other perishable items that have gone bad due to the effects of the cyclone. The Council’s chief executive Premila Kumar said supermarkets and other food stores should destroy such items.

Survivors spoke of the horror of the cyclone, while aid workers scrambled to help victims.

“The noise was deafening. At one point, I turned to my partner and questioned whether we would actually survive,” Sarah Bingham, an Australian on holiday on Tokoriki Island, told Reuters by telephone.
