In Mozambique, at least 15 people were killed and more than 45,000 have been affected, while Malawi has reported at least 11 deaths, with nearly 217,000 people impacted, according to ECHO. It said that heavy rainfall had caused rivers to overflow, and that floods and landslides resulted in casualties and widespread damage.
Though Ana has weakened, the South African Weather Service said that Malawi and Zambia could experience more heavy showers over the weekend.
A spokeswoman for the World Food Programme told CNN that agricultural land, key infrastructure and houses have been damaged, while lives and livelihoods have been lost.
“Southern African countries have been repeatedly struck by severe storms and cyclones in recent years that have impacted food security, destroyed livelihoods and displaced large numbers of people,” she added.
Several parts of Africa have battled destructive floods over the past year as they deal with the twin issues of prolonged drought and an increase in the intensity of rainfall, which create prime flooding conditions.
The region impacted by Tropical Cyclone Ana is projected to see an increased intensity of such events as global temperatures rise.
“This latest storm to hit Mozambique is a blunt reminder that the climate crisis is very much a reality,” said Maria Luisa Fornara, Unicef’s representative in Mozambique, in a statement.
Earlier this week, Malawian President Lazarus Chakwera declared a state of disaster in areas affected by the cyclone.
“Since most of the areas are inaccessible and considering the large number of displaced households, additional resources are required to provide assistance to all the affected people.”
Chakwera went on to say that he had appealed for humanitarian assistance from “the international donor community, relevant United Nations agencies, non governmental organizations, the local private sector as well as all fellow citizens of goodwill.”
Tents, food and other essential items are urgently required, while rescue operations are also a priority, he said.
Teams from aid organization World Vision have been working on the ground this week to support those affected.
A meteorologist from the Met Office in London told CNN that “the footprint of ex-Tropical Storm Ana will continue to be the source of severe thunderstorms, bringing torrential rain across the affected area.”
“The remnants of Ana will slowly transfer westwards over the coming days and offer a ready source of moisture for some torrential showers and thunderstorms. Significant flooding impacts have already been reported across Malawi in association with this system.”
