The forecast through October indicates water deficits in Africa’s northwest and in coastal nations from Sierra Leone around the Gulf of Guinea. Surpluses are expected in the Sahel, Uganda, and from Tanzania through its southern neighbors and eastern South Africa.
Africa: Widespread water deficit in the north; surplus in Tanzania
The forecast through May shows widespread, intense water deficits emerging across northern Africa. Liberia and the Horn of Africa will transition from deficit to near-normal conditions. In Gabon, deficits will downgrade but remain intense, while deficits in central and southern Africa downgrade to moderate. Deficits are also forecast for: Guinea Bissau, western Burkina Faso, northern Ghana, northern Ethiopia, eastern Central African Republic, and western and southern Madagascar. Surplus is forecast for Tanzania, Uganda, Kenya, eastern South Sudan, southeastern Sudan, and southern Ethiopia.
Africa: Extreme water deficits forecast for Zambia & Malawi
A notable improvement is forecast for southern Africa and the Horn of Africa where conditions will transition from intense to mild water deficit. Intense deficits are, however, forecast scattered across the southern Sahara and the Sahel, and in a stretch from southern Democratic Republic of the Congo through eastern Zambia into Malawi. Deficits of varying severity remain dominant in many other regions, but surpluses are forecast for northeastern South Sudan and Tanzania, and will be exceptional in Tanzania. After April, severe deficits will emerge across northern Africa and will persist in Zambia.
