Rain advances across the country. Starting this Thursday (11), the rain gains strength in part of the Center-South of Brazil and draws attention mainly in the Southeast and Center-West, regions that normally enter a drier period at this time of year. June is usually a month of little rain in most of these areas, but the forecast indicates a sequence of days with instability, heavier skies and frequent showers until at least next week. 📱Download the g1 app to see news in real time and for free The highlight is the Southeast and Central-West, where volumes may be higher than expected for June in several areas. The rain should mainly hit São Paulo, Mato Grosso do Sul, parts of Minas Gerais, Rio de Janeiro and then advance more irregularly to Goiás, Mato Grosso, Distrito Federal and Espírito Santo. In the South, instability also appears strongly, with a risk of moderate to heavy rain in Paraná, Santa Catarina and the north of Rio Grande do Sul. The change in weather is related to the formation and passage of cold fronts, in addition to areas of low pressure that help organize heavy clouds between Paraguay, the South and the Central-West of Brazil. These systems also favor the transport of moisture to the interior of the country. "What makes this condition more atypical is the frequency with which these cold fronts pass", explains César Soares, meteorologist at Climatempo. According to him, in June, rain tends to be much more limited in these regions, which means that any sequence of instability has a greater weight in the month's accumulation. "In June, it doesn't usually rain so much in these regions. Therefore, the showers predicted for the next few days may cause some areas to reach, in just two or three days, or over the course of a week, volumes close to the average expected for the entire month", he states. César further explains that this occurs because the average accumulated figures for June are very low. "In parts of the Central-West, for example, the average rainfall during this period is close to zero. In the Southeast, volumes are also usually reduced, including in capitals like São Paulo", he says.
