South America: Water deficits to downgrade in Brazil but remain widespread
The extent of exceptional water deficit in the region will diminish considerably through December, though deficits will cover most of Brazil and will be intense across the north, in Mato Grosso, São Paulo, and Paraná. Intense deficits are also forecast in Bolivia from east of La Paz through Cochabamba to the south, and from southern Peru through the Atacama Desert in northern Chile past Santiago. Surpluses will persist in Uruguay, and in Entre Rios and Buenos Aires Provinces in Argentina, and will emerge in Rio Grande do Sul, Brazil.
South America: Large pockets of intense water deficit to persist in Brazil
Exceptional water deficits will diminish over the next few months, but large pockets are forecast for Brazil in Acre, Rondônia, Pará, Tocantins, Goiás, Minas Gerais, Mato Grosso do Sul, and São Paolo. Intense deficits elsewhere include: Venezuela east of Lake Maracaibo and near the border with Guyana; southern Bolivia; and along a path beginning south of Lima, Peru, through northern Chile. Deficits in Argentina will moderate and surpluses will emerge in northern Buenos Aires Province.
South America: Water deficits in northeastern Argentina to downgrade but persist
The extent of exceptional deficit will diminish considerably over the next few months. However, pockets are forecast in Amapá, Amazonas, Acre, Maranhão, Goiás, Minas Gerais, Mato Grosso do Sul, and São Paolo, Brazil; and, southeastern Venezuela, eastern Suriname, and French Guiana. Exceptional deficits in northeastern Argentina will downgrade to severe. Surpluses are forecast for northern Bolivia and eastern Paraguay. After June, moderate to severe deficits will continue to emerge across the northern bulk of the continent. Aforementioned deficits in Argentina will moderate.
South America: Water deficits forecast to diminish considerably but persist in Brazil
A significant retreat of exceptional deficits is forecast November through January, though deficits are forecast for much of Brazil’s northern half and along its southeast coast from São Paulo to Rio de Janeiro. Intense surpluses are forecast for central Colombia and Venezuela’s northeastern coast into Trinidad and Tobago. Moderate surpluses are forecast for northern Peru, northern Bolivia, southern Paraguay, and Buenos Aires Province, Argentina. After February, a transition from deficit to moderate surplus is forecast for northern Amazonian Brazil.
