Hundreds more were missing Sunday while tens of thousands were cut off from roads and telephones in mainly poor, rural areas.
Cyclone Idai has affected more than 1.5 million people in Malawi, Mozambique and Zimbabwe, according to the UN and government officials.
This drew criticism from some who thought they should have stayed at home to deal with a disaster whose overwhelming magnitude has not been experienced in years.
In Zimbabwe, 31 people have died from the floods, said the country's information ministry.
Mozambique's central port city of Beira was hardest hit, with the airport closed and many homes destroyed.
Zimbabwe's president was returning home from the United Arab Emirates "to make sure he is involved directly with the national response by way of relief to victims of Cyclone Idai," the information ministry said Sunday.
