2017 South America autumn forecast: Rain to aid wildfire danger in Chile; Brazil faces unrelenting drought
Rain and thunderstorms will frequent much of South America this autumn as wet weather occurs from Argentina to parts of Colombia and Venezuela.
Drought to improve in Colombia, Venezuela but worsen in northeastern Brazil The drought gripping Colombia and Venezuela will improve with a wet pattern continuing into autumn.
This includes helping to raise the water level at the Guri Dam, one of the largest water reservoirs on Earth.
While rain helps to improve the drought in Colombia and Venezuela, dry weather will cause drought conditions to worsen in Brazil.
Some rain is expected to move over these areas throughout the season; however, below-normal rainfall will cause the drought to persist and possibly worsen.
Rounds of rain, thunderstorms to slam Argentina to southern Brazil An active weather pattern is on tap for much of Argentina, Paraguay, Uruguay, Bolivia and southern Brazil this season as waves of rain and thunderstorms move across the region.
“It seems like there will be an active weather pattern with no prolonged dry periods and near- to above-normal rainfall,” Miller said.
The threat for thunderstorms will be mainly early in the season before gradually tapering off as the fronts deliver steadier rain instead, AccuWeather Lead International Meteorologist Jason Nicholls said.
Most of Chile should see near-normal rainfall, but a few pockets could receive above-normal rainfall, Miller added.
Warm, dry weather is also on tap for southern Argentina and southern Peru.
