São Paulo State, Brazil has been facing the worst water crisis since 19th century, when precipitation measurement officially began. The summer of 2013/2014 was the driest in the last 80 years in the state. Estimate the amount of precipitation that occurred in a certain region and calculate the difference from other periods can help water manager not only on planning, but also in the decision-making process. The aim of this work was to estimate the accumulated precipitation during this dry period in the Médio Paranapanema hydrographical region (UGRHI-17), located at the western part São Paulo state, Brazil, an hydroelectrical and agricultural hotspot of the state. We mapped precipitation rates accumulated during 2013/2014 hydrological year (from September to August) using Tropical Rainfall Measuring (TRMM) satellite data and then we compared the results to precipitation maps produced between 2000 and 2010 using data from the same source to verify possible impacts in the deacreasing precipitation rates of the region. It was observed that the hydrological period of 2013/2014 received the lowest precipitation rate in relation to the studied periods, the eastern portion of the region being the most affected area in terms of water scarcity
