Three countries in southern Africa were hit this week by Storm Ana, which displaced thousands and killed a hundred.
Madagascar has recorded at least 48 deaths and 130,000 people have been displaced from their homes to makeshift shelters, the BBC reported.
Malawi has recorded at least 11 deaths. This disaster has led to a power outage across the country and some areas have been declared disaster zones, the BBC added.
The authorities have declared a state of natural disaster.
Mozambique, meanwhile, has reported 18 deaths. More than 10,000 homes and dozens of schools and hospitals have also been destroyed in the country, while power lines are down.
Meanwhile, authorities said the exact number of victims is still unknown, with 20,000 affected by the floods.
The country experienced heavy rain and thunderstorms that continued to hit some regions even after the storm passed, contributing to flooding in the region.
Prime Minister Carlos Agostinho do Rosário said that while Mozambique was not asking for help, the remnants of the disaster were not something a country could address.
“We are a country that does not contribute much to climate change, and yet we are one of the countries that suffers the most from its impact,” he said.

Some 44 emergency camps have been set up to care for thousands of displaced and injured people, the BBC said.
