The dry climate and fires create a residual layer of thick pollutants that cover the city of São Paulo, Brazil. According to Climatempo meteorologists, the city of São Paulo may experience black rain, due to pollution and soot from the burning of the Pantanal and also from the interior of the state. In addition to the darker rain, there is a possibility that the sky will turn orange during the day. The forecast for the next few days is strong, but with rain.
