South America: Exceptional water deficits persist in central Brazil

South America: Exceptional water deficits persist in central Brazil

South America is forecast to transition away from widespread exceptional water deficits after October. However, until then exceptional deficits are forecast for much of Brazil north of Rio, along with deficits of varying severity elsewhere in South America. By December the extent of exceptional water deficits in Brazil will diminish except along the Amazon River and in Amapá and Maranhão. From November on moderate deficits are forecast in Colombia, Venezuela, Guyana, Suriname, French Guiana, Ecuador, Peru, Chile, and Rio Grande do Sul, Brazil.

South America: Water deficits to persist in central Brazil, Chile, southern Argentina

South America: Water deficits to persist in central Brazil, Chile, southern Argentina

Exceptional water deficits are forecast for much of northern and central Brazil from July into October. From October to December deficits will diminish in central Brazilian states but persist across the north, and widespread deficits will emerge in other countries in northern South America. Deficits will also persist in Peru, Chile, and southern Argentina. 

South America: Water deficits to persist in central Brazil, surpluses ahead in Sao Paulo

South America: Water deficits to persist in central Brazil, surpluses ahead in Sao Paulo

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.

South America: Water deficits persist in the Amazon Basin, surpluses forecast in Venezuela’s Orinoco Basin

The forecast continues to indicate widespread and in many areas exceptional water deficits across northern South America, particularly in the Amazon Basin. Water surpluses are forecast May through July in Venezuela’s Orinoco and Caroni River Basins and in much of Guyana. Water surpluses will persist in Rio Grande do Sul, Brazil; Uruguay; and central Argentina.  

South America: Exceptional water deficits to persist across northern South America, particularly the Amazon Basin

Overall, exceptional water deficits are forecast to persist across northern South America, particularly in the Amazon Basin. Deficits are also forecast in Peru and Chile. Water surpluses are forecast in Paraguay; Uruguay; the Ibara Wetlands and Buenos Aires, Argentina; and Rio Grande do Sul, Brazil.

Many analyses reported in ISciences-authored blog posts are based on data generated by the ISciences Water Security Indicator Model (WSIM). Other sources, if used, are referenced in footnotes accompanying individual posts. WSIM is a validated capability that produces monthly reports on current and forecast global freshwater surpluses and deficits with lead times of 1-9 months at 0.25°x0.25° resolution. This capability has been in continuous operation since April 2011 and has proven to provide reliable forecasts of emerging water security concerns in that time-frame. WSIM has the ability to assess the impacts of water anomalies on people, agriculture, and electricity generation. Detailed data, customized visualizations, and reports are available for purchase.
