Global Precipitation & Temperature Outlook April 2018
The April 2018 Outlook indicates wetter than normal conditions in India, East Africa, and northwest Brazil. Significantly warmer than normal temperatures are forecast for Far East Russia and Alaska, much of eastern China, particularly the Yangtze River Basin from Shanghai to Chongqing, and eastern Australia from Brisbane to Canberra.
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.
South America: Widespread water deficits in Brazil to persist but moderate
The near-term forecast indicates that widespread water deficits will persist, though moderate, in Brazil. However, intense deficits are forecast for: Brazil’s far north into Suriname and French Guiana; Ceará and Rio Grande do Norte; north-central and southern Venezuela; Cochabamba, Bolivia; northern Chile; and Tierra del Fuego. Surpluses will persist in La Pampa and Buenos Aires Provinces, Argentina, and will emerge in Uruguay. After November deficits will retreat to eastern Brazil and surpluses will emerge in the northern Amazon Basin.
