The forecast through March 2020 indicates that water deficits in the region will shrink considerably. Nearly normal water conditions are forecast for much of the Amazon Basin in Brazil and eastern and southern states, but intense deficits will increase in central Brazil. Deficits will persist in much of Chile. Areas of surplus include Venezuela’s Orinoco Delta, central Colombia, and northern Peru.

Surpluses will increase in northeastern states. Exceptional deficits will trace a path along the Pacific Coast from Lima, Peru reaching almost to Santiago, Chile. Surpluses will increase and intensify in Paraguay.
The forecast through April indicates that water deficits in the Amazon Basin will shrink. Deficits are forecast for many other parts of Brazil, including intense deficits in Maranhão, eastern Goiás, Minas Gerais, São Paulo, and along many rivers. Deficits are also forecast for Brazil’s northern neighbors, and Peru and Chile. Surpluses are forecast for central Paraguay, northeastern Argentina, Uruguay, and Rio Grande do Sul, Brazil.
