Drought is universally acknowledged as a phenomenon associated with scarcity of water. Proper assessment of rainfall is an essential need to reduce the intensity of drought. Present work aims study the space-time variation in the rainfall of the eastern part of the Satara district of Maharashtra using the Rainfall Anomaly Index (RAI). Daily precipitation data of sixteen meteorological stations were used for the period between 1979 and 2013. RAI was calculated and plotted in spatial distribution maps. The overall investigation reveals that the eastern and southern part of the study area is prone to dry condition. The present investigation is useful to delineate potential sites of drought and through this study risk of future drought conditions can be curtailed.
