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. 

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.
