             abstract = "Heavy Rainfall Events (HREs) are usually associated with 
                         significant social and environmental disruptions. Landslides and 
                         floods causing injuries, deaths, and material losses might happen 
                         during these HREs. HRE usually are influenced by large scale 
                         systems with mesoscale precipitation systems embedded. In this 
                         study we analyze 10 HREs occurred in the Para{\'{\i}}ba do Sul 
                         River Basin (PSRB), between 2000 and 2012. The events are selected 
                         based on daily precipitation observed in 9 meteorological stations 
                         from the National Institute of Meteorology (INMET), located in the 
                         PSRB. All the events reach the 99th percentile for, at least, two 
                         stations. During these events serious damages were caused to the 
                         local population. The analysis is carried out by Satellite Images, 
                         Pluviometric data from 34 stations in the PSRB region, 
                         Pluviometric Data from Merge Database (Rozante et al., 2010) and 
                         Reanalysis data from CFSR (NCEP). The synoptic Analysis shows that 
                         most of the events occur during South America Convergence Zone 
                         (SACZ) events (8 of 10 events). Cyclonic Vortices embedded in the 
                         SACZ have been present in 6 cases (one VCAN P{\'a}lmen type). The 
                         other 2 cases are due to instability areas. The seasonal 
                         distribution shows that 7 cases occur during the summer, 2 in the 
                         spring and only one in the autumn. The Conclusion is that the SACZ 
                         is the main agent from heavy precipitation during the summer, in 
                         concordance with several authors (Carvalho et al., 2002; 
                         Dereczynski et al., 2009; Seluchi and Chou, 2009). The complex 
                         topography of the Basin Region is also determinant for the 
                         elevated totals of rain. Subsequently, the evets here studied are 
                         related to low previsbility systems occurring locally in an 
                         accentuated topography region, being very hard to predict.",
