The death toll from Chennai's widespread deluge, caused by Cyclone Michaung, has gone up to 17 on Tuesday, police said. While the hours-long heavy rain in the city stopped on Monday night, streets remained waterlogged.

Coastal Andhra Pradesh, meanwhile, saw massive downpour on Tuesday, after Cyclone Michaung made landfall in the state, between Nellore and Kavali. Authorities in the state have moved around 9,500 people from vulnerable areas into 211 relief camps across affected districts. No casualties were reported in Andhra Pradesh.

The 17 deaths that took place in Chennai since Monday were mostly due to drowning, electrocution, collapsing walls and falling trees. Several others were injured.

Tamil Nadu authorities have moved 32,158 people to relief camps over two days.

The death toll from floods and landslides in northern Tanzania following torrential rains over the weekend has risen to more than 50, with 750 acres of farmland destroyed, the president's office said on Monday.

Zuhura Yunus, spokesperson for President Samia Suluhu Hassan's office said in a statement that the landslides and floods had affected 1,150 households, or 5,600 people.

Severe flooding caused by El Nino and the Indian Ocean Dipole weather phenomena has killed hundreds of people in Kenya, Somalia and Ethiopia, and forced hundreds of thousands from their homes since seasonal rains began in October.

At least 65 people have been killed in landslides and flooding triggered by heavy rainfall in northern Tanzania, Prime Minister Kassim Majaliwa said on Tuesday, revising the death toll of 68 given by regional officials a day earlier.

Torrential downpours over the weekend washed away vehicles and brought down buildings in the hillside town of Katesh, 300km (185 miles) north of the capital, Dodoma.

"Two more bodies were found in the ongoing search and now the death toll has reached 65," Majaliwa said.

Images broadcast on television showed debris from houses, including furniture, strewn across streets, with key roads, power lines and communication networks disrupted.

"From around five in the morning [on Sunday], I heard loud bangs outside the house. When we tried to escape, it was too late because mud, trees, and stones were rolling from the mountain," said a man named James, who lost his wife and daughter in the disaster.

Some 5,600 people have been displaced by the landslides, said Mobhare Matinyi, a government spokesperson.

Rashid Ntandu, 24, lost his house in the disaster and found shelter in a school in Katesh which has been turned into a refuge centre.

"I believe there are more bodies covered by mud," he said.
