Above-normal rainfall ranging between 40 and 200 millimetres is expected across the country in May, according to the weather forecaster.

As noted, this is way above the usual long-term average which previously varied between 30 and 100 millimetres.

According to Anthony Twahirwa, the Division Manager of Weather and Climate Services Application at Rwanda Meteorology Agency, the flooding in the East African region is being triggered by the El Niño effect, a climate phenomenon that describes the unusual warming of surface waters in the eastern tropical Pacific Ocean which triggers heavy rains.

El Niño-induced heavy rains and flooding (riverine and flash floods) continue to hit parts of the eastern African region, including Burundi, Ethiopia, Kenya, Rwanda, Somalia, South Sudan, and Sudan.

It is associated with increased rainfall, often causing flooding in the Horn of Africa and the southern United States of America, and unusually dry and warm conditions in Southeast Asia, Australia, and southern Africa.

Tanzania

Experts warn that Tanzania, one of the sources of food to the region, will realise reduced yields by up to 30 per cent due to the impact of the floods, The East African reported.

In Tanzania, by Wednesday last week, the government had announced the deaths of 63 people.

Government Spokesperson Mobhare Matinyi said 8,532 houses have been damaged in Morogoro and Coast regions and 76,698 hectares of farms destroyed.

The country’s Prime Minister Kassim Majaliwa told Parliament flooding had left at least 236 injured, while more than 10,000 houses had been damaged and upwards of 200,000 people affected.

"The heavy El Nino rains, accompanied by strong winds and flooding and landslides in various parts of the country have caused adverse effects,” Majaliwa said.

The rains cut off movement between Kenya and Tanzania on the Nairobi-Namanga highway for the better part of Wednesday, after the Athi River burst its banks flooding a large part of residential and industrial areas in Kajiado and Machakos counties.

Eight camps have been established in the Coast region to accommodate 1,529 flood survivors and one in Morogoro.

The government has provided 40,000 tonnes of foodstuffs such as maize and rice and medicines and medical equipment worth $83,588 were donated to the people in the camps.

Uganda

In Uganda, flash floods made movement on the Northern Corridor difficult.

Last week, the Masaka-Mbarara highway – which is also Uganda’s main trade route to Rwanda and DR Congo – was cut off by floods, paralysing traffic, and the Kyambogo-Banda road was also cut off while in the Industrial Area, traders were left counting losses as they kept their shops closed due to flooding.

Burundi

In Burundi, Lake Tanganyika’s rising waters invaded the port of Bujumbura, disrupting business and making movement difficult for people and goods.

The rising waters of Lake Tanganyika have caused the Kanyosha River to overflow, damaging homes and other property in Bujumbura.

Burundi’s Interior Minister Martin Niteretse called for support in managing the crisis.

Between September 2023, and April 7, 2024, some 203,944 people were affected by flooding, with 19,250 homes and 209 classrooms destroyed in Burundi.

Meanwhile, Malawi, Zambia, and Zimbabwe have now declared national disasters as a result of the El Nino-induced drought, which has devastated their food production and wiped out most of their staple crops.
