Fijian officials were assessing the damage on Sunday after one of the most powerful storms recorded in the southern hemisphere tore through the archipelago, with early reports of widespread devastation in remote villages and one confirmed death.
Reports from the ground said entire villages had been wiped out by Cyclone Winston, a Category 5 tropical cyclone that packed winds of 230 kph (143 mph), with gusts of up to 325 kph (202 mph).
The storm hit Fiji late on Saturday, having changed direction at the last minute to spare the capital Suva the full force of its winds.
"Some villages have reported that all homes have been destroyed," Jone Tuiipelehaki of the United Nations Development Program tweeted late on Saturday. "Fifty homes have been reported destroyed in the Navaga village in Koro Island."
Businessman Jay Dayal, who lives near Rakiraki, on the north coast of Fiji's main island where the cyclone hit land, said the storm damage was extensive.
"I wouldn't be surprised if people are now starting to go without food," Dayal told Reuters. "It looks like a different country, it doesn't look like Fiji."
Humanitarian agencies warned Fiji may be facing a potential health crisis, mainly due to the lack of electricity. Low-lying river areas where hundreds of people live in tin sheds are also particularly vulnerable, aid workers said.
"We need electricity to ensure pumps are working and for sterilization," Raijeli Nicole, an official of aid agency Oxfam, told Reuters by telephone that flights have been scheduled on Sunday to assess damage in remote areas.
