The number of people missing on Madeira has jumped to 32, authorities said, after weekend landslides crashed down the Portuguese island's steep slopes, smashing into homes and leaving 42 confirmed dead.
The missing may never be found because they were most likely swept out to sea, officials said. Rescue teams were using sniffer dogs to scour debris and dug cars out of mounds of sludge to see if anyone was inside.
The number of missing was raised from four earlier in the day after local people contacted authorities, said Conceicao Estudante, the regional head of tourism and transport.
"The situation is totally different from this morning," Ms Estudante told reporters. "There are now 32 missing people, all of them identified by name."
Ms Estudante said 13 victims still had not been identified. She asked family members to go to a makeshift morgue at Funchal airport.
Seven members of an eight-member family died when their hillside home was swept away, Radiotelevisao Portuguesa reported.
Officials said 18 of 151 people admitted to Funchal's main hospital were still being treated. Some 150 people were homeless.
Officials said all the 42 confirmed dead were either from Funchal, the island's capital, or Ribeira Brava, a village at the foot of a valley about 15 kilometres from Funchal. The two oceanside communities bore the brunt of the mud and rock slides after a storm Saturday dumped the rainfall of a normal month in just eight hours.
Rescue teams used dogs flown in from Lisbon to search for the missing.
"We are sifting through the debris," the president of the island's regional government, Alberto Joao Jardim, said in an interview with public broadcaster Radiotelevisao Portuguesa. "My fear is that the missing will be recorded as lives that were lost."
The Portuguese government announced three days of mourning for the victims of Madeira's worst disaster in living memory.
Crews in Funchal pumped water out of a shopping mall's underground parking lot, where they feared they might find more bodies. The lot's two levels were submerged in the freak deluge. A nearby street was littered with earth-filled cars and stacks of catalogues used as stepping stones through the mud.
Emergency crews used bulldozers and front-loaders to remove tons of caked mud, boulders and fallen trees from drains and rivers, hoping to speed water runoff and prevent further flooding.
"We've been going flat-out for 48 hours and we'll keep going till the job's done," Funchal Mayor Miguel Albuquerque said.
Portugal's internal administration minister Rui Pereira said in Lisbon that authorities were sending a second batch of aid to the island.
A military transport plane was heading to Madeira with more sniffer-dogs, high-powered pumping equipment and equipment for army sappers to replace collapsed roads and bridges, Mr Pereira said. He said Madeira's financial needs were still being calculated.
Madeira, a popular tourist destination, is the main island of a Portuguese archipelago of the same name in the Atlantic Ocean just over 480 kilometres off the west coast of Africa.
