Studies indicate a trend of increase of extreme precipitation events throughout the last years in southern Brazil, usually associated with climate change. Diverse consequences in the amount and intensity of rainfall can be observed in different regions. Based on the literature, it is understood that there is no simple mechanism to explain the causes of extreme precipitation events in Santa Catarina due to the climatic complexity of the transition zone in which the state is located. There is a tendency for changes in the frequency and intensity of extreme events and their relation to the ENSO event, as in the mechanisms that change their spatial distribution. This paper aims to evaluate and compare an event from 2011 september with recent works and identify, considering El Niño and La Niña phenomenona, Santa Catarina susceptibility in extreme and persistent events. These results collaborate to understand the changes in the rainfall patterns and can be used by decision makers in climate change adaptation strategies. Therefore, decision makers working with climate studies agencies, must approach to predict such events and mitigate potential damage in face of such demands in Santa Catarina for extreme persistent events.
