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.
Exceptional water deficits are forecast to persist across central and much of northern Brazil through August. Surpluses are forecast to emerge in Sao Paulo. Thereafter and through November the extent of exceptional deficits in Brazil will diminish, but deficits of varying severity will continue to emerge and increase in extent throughout northern South America.
The outlook for June 2016 shows a dominant pattern of many severe to exceptionally warmer than normal temperatures - particularly in Brazil, North Africa, Southeast Asia, and Indonesia - along with a few pockets cooler than normal. Exceptional wet anomalies are forecast for portions of Brazil, Argentina, Peru, Ecuador, and Colombia. Severe to extreme wet anomalies are forecast for portions of Texas, Mexico, Afghanistan and Uzbekistan. Dry anomalies are forecast for portions of Uruguay, Brazil, Spain, Ethiopia, and India.
