Large regions of exceptional “snow drought” are reported in the northeast United States, southern Canada, the Italian Alps, and much of Eastern Europe and western Russia, along with large snow surpluses in the western US, Central Russia, and Mongolia. In the first quarter of 2016, much of the snow surplus in the western US is forecast to transition to deficit, and extensive snow deficits are forecast to emerge in western Canada.
Africa
Exceptional deficits throughout Africa will persist in northwestern, northern, and central countries. Surpluses will remain along the Sahel.
South America
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.
*Water Watch Lists
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.
*Special Topics, South 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.
Australia & New Zealand
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.
