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.
