South America

South America: Water deficits in northeastern Argentina to downgrade but persist

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 surplus forecast for Paraguay; deficit Venezuela

South America: Water surplus forecast for Paraguay; deficit Venezuela

Water deficits will diminish, returning many regions of Brazil to near-normal conditions. However, pockets of intense deficit are forecast for northern Amapá, Acre, Amazonas, Minas Gerais, Mato Grosso do Sul, São Paolo, and Rio Grande do Sul, as well as southern Venezuela, eastern Suriname, French Guiana, and the Gulf of Corcovado in Chile. Severe deficits are forecast for Uruguay and a large block in eastern Argentina. Areas of surplus include much of Paraguay, where conditions may be exceptional in the northwest, and pockets in Venezuela. 

South America: Water deficits forecast to diminish in eastern Brazil

South America: Water deficits forecast to diminish in eastern Brazil

Exceptional water deficits are forecast to diminish considerably in the coming months, but pockets are forecast through April in southern Venezuela, Amapá (Brazil), western Brazil, western Ecuador, and around the Gulf of Corcovado in southern Chile. Deficits are also forecast in southern Colombia, northern Peru, Uruguay, Rio Grande do Sul (Brazil), and northeastern Argentina. Surplus is forecast in northeastern Venezuela, scattered throughout eastern Brazil, northern Bolivia, and eastern Paraguay. After April, the extent of anomalous water conditions will shrink. 

South America: Much wetter than normal conditions forecast for Paraguay

South America: Much wetter than normal conditions forecast for Paraguay

A number of significant transitions are forecast for the next three months. Though exceptional water deficits will diminish across northern South America – transitioning to surplus in many northern nations and the northern Amazon Basin – deficits will intensify in eastern Brazil. Surpluses are forecast to emerge throughout Paraguay and into southern Brazil. Surpluses in Uruguay will transition to moderate deficit; Buenos Aires Province, Argentina will transition from surplus to near-normal. After March, water anomalies will moderate considerably across most of the continent.

Exceptional water deficits are forecast to diminish considerably over the next three months except in the western Amazon Basin in Brazil and Acre, Rondônia, Mato Grosso, and Tocantins. Deficits are also expected across Brazil’s Northeast region. Elsewhere on the continent, intense deficits are expected in western Bolivia and the Gulf of Corcovado, Chile. Areas of surpluses include central Colombia; Mato Grosso do Sul, Brazil; and La Pampa Province, Argentina. After February widespread surpluses will emerge in the northern Amazon Basin and Venezuela, Guyana, and Suriname.

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.
