Rescuers were moving in to help people trapped by rapidly rising floodwater in the northern Mozambique city of Pemba on Sunday as Cyclone Kenneth dumped more rain on the region.
The storm slammed in to the province of Cabo Delgado on Thursday, killing five people, and has since then pounded an area prone to floods and landslides with rain, fuelling fears rivers could burst their banks and leave vast areas under water.
It was raining heavily in Pemba on Sunday, which had until now been spared from severe damage and a number of neighbourhoods in city of 200,000 people were now flooded, Saviano Abreu, spokesman for the U.N. Office for the Coordination of Humanitarian Affairs (OCHA) in southern and eastern Africa said.
"There are already people in need of search and rescue," he said, adding a team was on their way to the neighbourhood of Natite, in the city's north. "We unfortunately are expecting devastating floods in Pemba."
Aid workers were currently working to assess the scale of the flooding both in Pemba and the surrounding areas, where there were reports of waist-high water, he continued.
Mozambican authorities on Friday urged people living near two rivers in the province, one to the north of Pemba and the other to the south, to move to higher ground as rivers began to fill up and overflow.
'Entirely wiped out'
Cyclone Kenneth, packing storm surges and winds of up to 280 km per hour, struck Mozambique's northern coast just six weeks after Cyclone Idai, which flattened the port city of Beira and left entire villages under water. Idai killed 1,000 people across Mozambique, Malawi and Zimbabwe.
Kenneth could over the coming days dump twice as much rain on Mozambique, the World Food Programme has warned, sparking fears the impoverished nation could suffer another bout of deadly floods.
It has already caused huge destruction in some districts of Cabo Delgado, with one U.N. OCHA official saying some villages had been "entirely wiped out".
"They look like they have been run over with a bulldozer," Gemma Connell, head of OCHA's regional office, said.
