Rare snowfall lashes southern Brazil
Temperatures fell, with rare snowfall overnight in some places - as a polar air mass advanced toward the center-south of the global agricultural powerhouse, threatening coffee, sugarcane and orange crops with frosts.
Unusually cold weather in Brazil has already sent international prices for coffee and sugar higher.
The polar air mass should move over Sao Paulo and Minas Gerais, major producers of sugar, citrus and coffee, on Friday, bringing freezing temperatures.
