The aim of this paper is an attempt to answer the question whether it is necessary to update the probabilistic model of heavy rainfall with the passage of time. Based on IMWM-NRI measurement data in Wroclaw, probabilistic models for data from 1960–2009 with data up to 2017 were compared. The analysis showed that intense rainfall recorded in recent years can significantly affect the course of the depth-duration-frequency (DDF) model.
