2017 South America winter forecast: Drought to worry Colombia, Venezuela; Frequent storms to strike Chile, Argentina.
Meanwhile, warm waters in the Pacific Ocean will help to spread rain across much of the western countries of South America.
Argentina to face more rain, mountain snow than last winter Rounds of rain will frequent Argentina this winter as storm systems move across the country on a regular basis.
“More storms are expected across central Argentina this year versus last year with near- to slightly above-normal rainfall in cities such as Buenos Aires,” AccuWeather Lead International Meteorologist Jason Nicholls said.
Drought concerns to return to Colombia, Venezuela Drought has plagued Colombia and Venezuela in recent years, and this winter will bring little relief to the countries.
“Drought concerns will return along the Caribbean coast of the continent from northern Colombia and Venezuela to French Guiana,” Nicholls said.
Warm waters off the coast of Brazil may keep drought conditions from returning to far northeastern Brazil, Nicholls said.
While winter is not typically a wet time of year, drought conditions could develop in the Brazilian states of São Paulo to Minas Gerias, Nicholls said.
Wet winter on tap from Chile to Peru Frequent storms will bring rounds of rain and mountain snow to Chile this winter with the tracks of the storms shifting as the season progresses.
“The warm waters over the Pacific Ocean will lead to wetter-than-normal conditions from Ecuador and Peru into Bolivia,” Nicholls said.
