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.

However, much of the rain will stay away from northeastern Brazil, an area plagued by long-term drought.

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.

The first half of the season will be wetter than the second half, with the heaviest rain expected across the southern parts of Colombia and Venezuela.

This rain is not likely to end the drought, but it should help improve conditions in the near term. 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.

“There has been a little bit of drought relief in northeast Brazil, but the drought has been pretty persistent,” AccuWeather Meteorologist Rob Miller said.

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.

Salvador, Fortaleza, São Luís and Recife are expected to receive below-normal rainfall throughout the season.
