A significant retreat of water deficits is forecast October through June, but through December exceptional deficits are expected in northernmost Brazil and into neighboring countries. Deficits are also forecast north of Lake Titicaca in Peru through La Paz and Cochabamba, Bolivia and into Argentina. Widespread, primarily moderate deficits are predicted in much of eastern Brazil, which may be more severe along the coast of the State of São Paulo. Surpluses are forecast in central Colombia, northern Peru, northern Bolivia, eastern Argentina, Uruguay, and O’Higgins Lake in Patagonia. After December widespread moderate surpluses are forecast in the northern Amazon Basin
South America: Large pockets of exceptional water deficits in Brazil
The forecast through July shows water conditions similar to the prior three months: large, widespread pockets of exceptional deficits in Brazil, and deficits along many Brazilian rivers. Deficits in southern Venezuela are forecast to increase in severity while those in the north recede. Severe to exceptional deficits are expected to persist in northern Chile. Surpluses are forecast to emerge in Bolivia east of Lake Titicaca; surpluses in eastern Paraguay will increase; and surpluses will persist in Buenos Aires, La Pampa, and Neuquén Provinces in Argentina.
