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.
Water deficits are expected to shrink and downgrade significantly through January with conditions approaching normal in Iraq, Syria, northeastern Saudi Arabia, and Iran. Deficits will intensify in Georgia, and extreme deficits will emerge on the Kura River in Azerbaijan. Intense deficits are also forecast for southern Saudi Arabia, Yemen, and, to a lesser degree, western Turkey and along Turkey’s Black Sea coast.
Through November extreme to exceptional deficits will dominate much of Saudi Arabia, southern and western Iraq, Kuwait, large pockets of southern Iran, Qatar, and United Arab Emirates. Primarily moderate deficits are forecast for the Levant. Deficits of varying intensity are forecast for much of Turkey and will be severe in central Turkey, along its northeastern coast, and through Georgia.
Intense water deficits will persist in many parts of the region through October after which conditions will moderate overall. For the next several months, exceptional deficits are forecast for Saudi Arabia, southern Iraq, Kuwait, United Arab Emirates, and southern Iran. Conditions in Gaza and Israel will be fairly intense as well and severe deficits are forecast for West Bank, Yemen, western Oman, Qatar, and western Iraq. Deficits of varying severity are forecast for Turkey and Georgia.
The forecast through August indicates that exceptional water deficits in the northern Arabian Peninsula will shrink but deficits overall in the Peninsula will be widespread. Exceptional deficits are forecast for Lebanon, Israel, and West Bank. Deficits of varying severity are forecast throughout Turkey and Syria, though deficits in western Turkey will downgrade from exceptional. In southern Iran deficits will become more severe, reaching exceptional intensity in Kerman and neighboring provinces.
