Exceptional deficits throughout Africa will persist in northwestern, northern, and central countries. Surpluses will remain along the Sahel.
Exceptional deficits will remain throughout the Amazon and the Boliviarian Nations. Similar deficits will occur in northeastern coastal regions of Brazil, in Argentina, and in Chile.
The forecast for November 2024 expects significant water deficits for the 12-month period of August 2024 through July 2025 in northern South America, Canada, northwestern and eastern China, and northern to central Africa. Areas expected to experience surplus include central Africa, South Asia, and Central America.
With the release of WSIM v3 and 8 years of additional data, we reevaluate drought risk in the Amazon and the historic drought that continue to affect the region.
The forecast indicates that extreme to exceptional surpluses in northern Australia will diminish, though will still remain present in some regions of Northern Territory. Exceptional deficits across the continent will similarly dissipate, though severe deficits are expected along the southern coast of Victoria.
The forecast through March 2020 indicates that water deficits in the region will retreat considerably, leaving pockets in western Turkey and its central Caspian Coast, Georgia and Azerbaijan, and southwestern Saudi Arabia. Intense surpluses will persist from central into northern Syria; around Mosul, Iraq; and along Iran’s Caspian Sea Coast and border with Turkmenistan.
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.
The forecast through July indicates that widespread, intense water surpluses will persist from northern Syria into southern Turkey, from the Tigris River in Iraq well into western Iran, and in northern Iran along the Caspian coast and the border with Turkmenistan. Widespread, intense deficits are forecast for the Arabian Peninsula. Extreme to exceptional deficits are forecast for Kuwait, southern Iraq, and west of the Euphrates. Severe deficits will emerge in central Iran’s Yazd Province.
