Brazilian Meteorological researchers Metsul have issued a black rain warning for the southern part of the region's largest country, which could also be affecting northern Uruguay Thursday -Cerro Largo, Rivera, and parts of Rocha- given a cold front clashing with a smoke plume from the large number of fires in the region, it was explained.
Smoke from bushfires raging across Australia reached Brazil on Tuesday, an arm of the National Institute for Space Research said on Twitter. Referring to satellite images, the agency's Department of Remote Sensing said the smoke had arrived in Brazil's southernmost state, Rio Grande do Sul.
