Severe to exceptional surpluses will remain throughout Queensland. Exceptional deficits will occur in portions of Victoria, Western Australia, Tasmania, and New Zealand.
Exceptional deficits will occur in northwestern and southeastern China, widespread throughout the Yangtze River Basin. Isolated pockets of surplus will affect portions of central and northeastern China.
Exceptional surpluses throughout Maritime Southeast Asia will mostly diminish, though pockets of severe to exceptional deficits will persist in portions of the Philippines, Indonesia, Papua, West Papua, and New Guinea.
Regions forecast to have significant water deficits for the 12-month period from April 2019 through March 2020 include: Suriname, French Guiana, Finland, Estonia, Latvia, Egypt, Cameroon, and New Caledonia. Areas with a forecast of significant water surplus include: the central United States, Paraguay, Syria, northern Iraq, southern Turkmenistan, Afghanistan, Tanzania, and southeastern China.

The forecast through August 2019 indicates widespread surpluses in the Ob River Basin, deficits in much of the Yenisei River Basin, surpluses in the Lower Volga, and deficits in the Middle and Upper Volga regions. Intense surpluses will persist in southern Turkmenistan but both deficits and surpluses are also forecast as transitions occur. Surpluses are also forecast for eastern Uzbekistan, western Tajikistan, Kyrgyzstan, and northern Kazakhstan.
The forecast through August 2019 indicates a transition away from widespread, exceptional water deficits in Australia to, overall, mild deficits or normal conditions. However, intense deficits are forecast for Tasmania, the southern tip of Western Australia, northern New Zealand, and New Caledonia. Moderate to severe deficits are expected from Brisbane to Canberra.
The forecast through August 2019 indicates that, though some areas will begin to transition out of water surplus, widespread surpluses will persist from northern Syria into southern and eastern Turkey, from the Euphrates River in Iraq well into western Iran, and in northern Iran along the Caspian coast and the border with Turkmenistan. Deficits will increase in central Turkey and on the Arabian Peninsula and will include exceptional deficits in central Saudi Arabia.
