The forecast through February indicates that water deficits will downgrade considerably. However, areas with notably intense conditions include western Ethiopia; pockets of northern Somalia, Nigeria, and southwestern Cameroon; southwestern Angola into Namibia; and, Lesotho and the Orange River region of Northern Cape, South Africa. Surpluses are forecast for Tanzania, southern Congo into western DRC and northern Angola, and south-central Chad.

The June Outlook indicates much warmer than normal temperatures (40+ years return period) blanketing a large block of Northeast China and stretching across the border well into Russia. Much of Europe is forecast to be warmer than normal, as well as many parts of Indonesia, while much cooler temperatures will prevail in parts of Central Africa. Conditions are expected to be much wetter than normal for several African nations along the Atlantic near the equator.
The May Outlook indicates wetter than normal conditions in East Africa, Uruguay, and Bangladesh. Much warmer than normal temperatures are expected in India, Egypt, Sudan, and Northeast China.
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.
Though the extent of exceptional water deficits across the continent will diminish from March through May, severe to exceptional deficits will continue to emerge across northern Africa, especially in Niger. Exceptional deficits are also forecast in southern Somalia and southern Gabon. Deficits are also expected in Congo, Rwanda, Burundi, southeastern Central African Republic, Democratic Republic of the Congo, northern Angola, Uganda, western Tanzania, Kenya, and northeastern Mozambique. Surpluses are expected in southeast Sudan, the Okavango Delta in northern Botswana into western Zambia, Zimbabwe, and northern South Africa. From June through August the overall picture will remain much the same, but worth noting is that extreme to exceptional deficits are forecast for nearly all of Egypt during this period, and deficits will emerge in Somaliland, northern Cameroon, and southern Angola.
Regions likely to have significant water deficits for the 12-month period from December 2016 through November 2017 include: Arkansas, Quebec, Brazil, Finland, Denmark, Libya, Niger, Gabon, Madagascar, Saudi Arabia, Yemen, northern Russia, Inner Mongolia, Thailand, western Cambodia, Papua New Guinea, and eastern Australia. Water surpluses are forecast for: Idaho, Central California, southwestern Zambia, the Okavango Delta in Botswana, northeastern Afghanistan, and between the Irtysh and Yenisei Rivers in Russia. This Watch List is based on ISciences Water Security Indicator Model (WSIM) Global Water Monitor and Forecast issued 8 March 2017.
The March 2017 Outlook indicates drier than normal conditions in southern California and eastern Brazil, and wetter than normal conditions in Venezuela, Guyana, Suriname, Paraguay, and Namibia and neighboring African nations. The forecast for many parts of the world is for much warmer than normal conditions including: Europe, Russia, Yemen, Queensland (Australia), Madagascar, Brazil, Cuba, and southwestern Mexico.
Most noteworthy in the November 2016 Outlook is the forecast of a vast expanse of exceptionally warmer temperatures for the US Midwest and northward through Canada. Significant warm anomalies are also expected in coastal West Africa, the Gulf of Guinea, Madagascar, India's southern tip, and Southeast Asia. Exceptional dry anomalies are forecast along South America's northern Pacific coast and in southern Ethiopia. Areas forecast to experience wet anomalies include northern Brazil and northern Australia.
The extent of exceptional deficits across Africa is forecast to shrink considerably through December. However, moderate to extreme deficits are forecast for eastern Central African Republic and Republic of the Congo, and exceptional deficits are also expected along rivers in South Sudan, Uganda, Somalia, and Kenya. Surpluses are forecast in southeastern Sudan into South Sudan and for the Nile. The forecast for January through March indicates primarily moderate water deficits across northern Africa, a scattered band of both deficits and surpluses across the Sahel, and primarily abnormal to moderate deficits in southern Africa.
