The forecast through July indicates widespread water deficits across central Brazil, exceptional in Tocantins, Mato Grosso, Goiás, and the Paraná River. Deficits are also expected in central Peru and much of Chile. Surpluses are forecast in the northwestern Amazon Basin.
South America: Water deficits in central Brazil
South America: Widespread, intense water deficits in much of Brazil
Though a slight reduction in the extent of exceptional deficits is expected, the forecast for the next three months indicates a basic pattern of water conditions similar to observed conditions in the prior three months which includes widespread, intense deficits in most of Brazil north of Rio de Janeiro and surpluses in La Pampa Province, Argentina. In addition, a transition from surplus to deficit is forecast in Brazilian states south of Rio and in eastern Paraguay. After October deficits across northern South America are forecast to shrink considerably.
