The forecast anticipates exceptional deficits to continue in northern and northwestern African countries, as well as some central and southern countries. Intense surpluses are expected to emerge in areas throughout the Sahel.
The forecast indicates that intense surplus will occur in most northern and central regions of Australia, with exceptional deficits diminishing in portions of the country near its western coast. Exceptional deficits are expected to emerge in Tasmania, as well as in pockets across New Zealand.
The forecast indicates that exceptional deficits will mostly dissipate in northeastern China, but continue in northern, southern, and northwestern portions of the country. Exceptional surplus is expected to diminish in southwestern China, though moderate to severe surpluses may continue in eastern regions of the country.
The forecast indicates that exceptional deficits in Mainland Southeast Asia will persist but lessen in size, while intense surpluses will expand throughout Maritime Southeast Asia.
The forecast through July indicates that water deficits will downgrade in the southern half of the continent and across its midsection from the Gulf of Guinea to the Horn of Africa but will intensify across northern Africa with exceptional deficits expected. Moderate to severe deficits are forecast in the south, with intense deficits in Namibia. Areas of surpluses include Tanzania, northern Madagascar, the mouth of the Congo River, and the northern coast of the Gulf of Guinea.
Significant water deficits will continue to emerge across the north, though exceptional deficits will shrink. Deficits will diminish in central and southern Africa but remain intense in Gabon, southeastern DRC, Zambia, and west-central Madagascar. Southern Africa will downgrade to mild deficit. Surpluses will persist in southernmost Sudan, downgrade along the White Nile, increase in Kenya, and emerge in eastern Uganda, Ethiopia, and along the Jubba and Shabelle Rivers through southern Somalia. Exceptional surplus will persist 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.
The extent of exceptional water deficits is expected to diminish considerably after September, though deficits of varying severity will remain in the forecast and will likely be more severe in the northern half of the continent. In the near-term, July through September, severe to exceptional deficits are forecast in the desert regions of the northern nations, Algeria, Libya, Egypt, northern Niger, and northern Sudan; and also in Equatorial Guinea and Gabon. Exceptional deficits will retreat in southern Namibia during this period but will emerge in the northeastern portion of the country, eastward into neighboring Botswana and across the border into South Africa. Exceptional surpluses are forecast to continue in eastern Tanzania though September but will retreat to the coast by December.
The extent of exceptional deficits across the African continent will diminish considerably through February, but pockets of extreme deficits will persist in eastern Ethiopia and Somalia through February and will emerge in Benin and Nigeria. Thereafter, deficits of notable severity will emerge in Niger, northern Sudan, and Egypt. Exceptional surpluses will persist through February surrounding Bangui in Central African Republic and through May around the White Nile in southeast Sudan and South Sudan.
