For a complete analysis, the authors also included cases of precipitation with a total of 15 mm or more for a period of no more than 12 hours. For the flat part of the Republic of Bashkortostan, urgent observation data were used at the Ufa-Dema weather station, for the mountainous part - at the Tukan weather station. Cases of heavy rains were detected from May to November in the period 1966-2018. The main regularities of the distribution of cases of heavy rains according to the criteria of the amount, timing, months of manifestation are shown.
