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.
Global Precipitation & Temperature Outlook for February 2018
Much warmer than normal temperatures are forecast in February for the US West, the Baja Peninsula, the Tibetan Plateau, and far northeastern Russia, including the Kamchatka Peninsula. Nearly all of India will be warmer than normal. Paraguay is expected to be cooler than normal. Eastern Brazil should see above average rainfall, as will central Mexico and western India.
Africa: Water surpluses forecast for SE Tanzania, NE & coastal Kenya
Severe to exceptional water deficits are forecast across northern Africa, Gabon, central Republic of the Congo, and western Madagascar through July or longer. Moderate to severe deficits are expected in northern Cameroon, eastern Central African Republic, southwestern Ethiopia, western Kenya, Democratic Republic of the Congo, Rwanda, Burundi, Angola, and northern Mozambique. Exceptional surpluses are expected to emerge in northeastern and coastal Kenya, and to re-emerge in south-central Sudan. Surpluses of varying intensity are forecast to persist in southeastern Tanzania, western Zambia, northern Botswana, Zimbabwe, and along South Africa’s border with Botswana. After July deficits in the north will persist, though diminish slightly in intensity and extent.
Africa: Water deficits forecast across the North & Gabon, DRC, Kenya
Widespread exceptional water deficits are forecast to emerge across northern Africa from April through June; deficits of lesser severity are forecast across Africa’s mid-section. Deficits in the Horn of Africa, DRC, and Angola are expected to downgrade to primarily moderate severity. Surpluses are expected in southeast Sudan into South Sudan, southeastern Tanzania, western Zambia, the Okavango Delta in northern Botswana, Zimbabwe, northern South Africa, and northern Madagascar. After June deficits across northern Africa are forecast to recede slightly overall, but severe to exceptional deficits are expected to emerge in southern Somalia, and moderate to severe deficits may emerge in northeast Namibia.
