Possible damage to agriculture.
A powerful cold air mass of polar origin is progressing over Brazil. Between July 1st and 8th, the country should feel a very intense cooling.
It will most likely be the most intense in 2019 and perhaps the only one of this magnitude this year. The cooling will initially be felt over the South of Brazil, but will begin to extend throughout the country from Wednesday, July 3rd.
The expected cold has the potential to produce below-freezing temperatures in the South and close to 0 C in the Southeast and Center-West. However the 10 C chill may be felt in Bahia and the North-Central areas of Goias.
Frost may generally form over the south of Brazil, reaching Curitiba and the north of Parana, and in areas of the midwest and southeast, with consequent damage to agriculture.
Frost may occur in Mato Grosso do Sul, in many areas of Sao Paulo, in central, western and southern Minais Gerais, in the highlands and southern Rio de Janeiro.
The risk of frost in southern Goias and high-altitude areas on the border between Minais Gerais and Espirito Santo such as the Caparao mountain range, should not be ruled out.
