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.
Exceptionally hotter than normal temperatures are indicated in the April 2022 Outlook for many regions in the Middle East, Central and South Asia, Siberia, and the Yellow (Huang He) and Yangtze River Basins in China. In Central Asia and parts of the Middle East conditions will also be drier than normal.
The July Outlook includes exceptionally warmer than normal temperatures in many areas, notably a vast block of eastern North America including the Great Lakes States, the U.S. Northeast, and well into Canada. Central Europe will be considerably drier than normal while wetter conditions are expected in the Balkans.
The forecast through July indicates that widespread water surpluses will nearly disappear in southeastern China but will persist in the south and will include exceptional anomalies. Taiwan will transition from deficit to moderate surplus. Exceptional deficits will persist in western Inner Mongolia, and moderate to extreme deficits in Mongolia. Deficits are forecast between the Yellow and Yangtze Rivers. Severe deficits are forecast for northern Japan.
The forecast through June indicates that widespread water surpluses will persist in southeast China but will moderate overall. However, anomalies will be extreme to exceptional in Guangxi and into western Guangdong. Intense surpluses will persist in the Tibetan Plateau. Intense deficits are forecast for Mongolia and from western Inner Mongolia in China across central Xinjiang. Moderate deficits will emerge in North Korea, and moderate to extreme deficits are forecast for Japan.
