Starting this Friday (March 27th), a heat wave will intensify over south-central Brazil, causing temperatures well above average for this time of year. The phenomenon is expected to primarily affect the states of Rio Grande do Sul, Santa Catarina, Paraná, São Paulo, Mato Grosso do Sul, Mato Grosso, and Goiás. This information comes from Metsul Meteorology. The heat is a result of a bubble of hot air over Argentina, associated with the continuous transport of hot air towards the continent. The lack of rain and dry soil in several areas also contribute to the rise in temperatures and the maintenance of this atmospheric pattern.
