The suffocating heat that has hit the country in recent weeks is running out. Autumn officially begins in the early hours of this Wednesday (20), at 00:06 Brasília time, and will bring significant changes in temperatures throughout Brazil.
According to Climatempo, the advance of a cold front on the first day of the new season will end the period of atmospheric blockage, which will facilitate the entry of some cold air into many Brazilian states. Thus, this week will end with low temperatures in the South and Southeast, and with relief from high temperatures in the Center-West of the country.

Risk of storms
This cold front will arrive in Rio Grande do Sul this Wednesday, but will quickly move to the state of São Paulo next Thursday (21). With this first impact, the north coast of SP will experience heavy rain showers that are expected to occur in the afternoon and evening, with a risk of lightning and wind gusts of up to 80 km/h.
Still on Thursday, the cold front will arrive in Rio de Janeiro, interrupting the strong heat but bringing a lot of rain at the end of the day, with the potential for storms in Costa Verde, in the regions of Resende and Volta Redonda, in Serra and in Grande Rio.
This type of rain is very favorable to river overflows and landslides, according to Climatempo, and can lead to disasters. Therefore, the agency recommends that the population pay attention to Civil Defense guidelines.
As these conditions advance over the Southeast, rain showers will also gain more intensity in Santa Catarina and Paraná, and the risk of storms will also increase in the capitals. With more moisture in the air, there will be the growth of heavy clouds over the east and south of Mato Grosso do Sul and the Triângulo Mineiro.
Next Friday (22), the weather will be closed in the Vale do Itajaí region (SC), in the coastal and eastern areas of Paraná, in the south of SP (including the coast and metropolitan region of the capital). The weather will be rainy in the center-south of RJ, with the possibility of “disturbances” in the lower reaches of Rio de Janeiro.
On the same day, cities in the south of Minas, the Zona da Mata region and part of the south of Espírito Santo are on alert for the risk of storms. The sea is rough in the South, in SP and RJ.
