                         South America between June/July 2020 has brought great 
                         socioeconomic damage to this region. The limited predictability 
                         due to the rapid deepening of pressure and surface, motivated the

                         information that can be used for the decision-making sectors. The 
                         synoptic description was made through reanalysis data from the 
                         European Centre for Medium Range Weather Forecasts, the 
                         observational responses of meteorological variables were obtained

                         Meteorology, atmospheric sounding and satellite images of GOES-16. 
                         The cyclogenesis observed at 11UTC on June 29, 2020 and showed a 
                         pressure drop of 35 hPa in the first 16 hours, with a decay rate 
                         of 2.2 hPa/h, reaching the value of 969 hPa in the center of the 
                         cyclone. In the following hours, an increase in the pressure value 
                         was observed in 3 hPa, reaching the value of 972 hPa in 24h. The 
                         pre-cyclogenetic environment contributed to the formation of an
