The methodology of the Standardized Precipitation Index (SPI) usage for evaluation of the level of water availability of the territory for the estimated period in comparison with long-term precipitation rate is given in this paper. Using the methodology of normalized parameters assessment gives possibility to make it comparable for different territories and regions as well as for different time scale, enable to conduct a retrospective analysis, evaluate the current situation or study the influence of probable climate change scenarios. Examples of water availability evaluation mapping of the South of Ukraine and Russia by SPI on the base of processing of the long-term precipitation records and weather data of spring 2014 with GIS tools using are given. Recommendations on the Standardized Precipitation Index application for the evaluation of agricultural and hydrological droughts and potential risk for waterworks objects have been proposed.
