It is well known that extreme precipitation associated with intensive rains could cause very significant problems in economical and social spheres of the countries. Heavy precipitation and consecutive flooding are the most serious weather-related hazards over the territory of Slovakia. The extreme precipitation analyses play a strategic role in many climatological and hydrological evaluations designed for the wide range of technical and engineering applications as well as climate change impact assessments. The paper deals with analysis of long-term variability and trends in one-day precipitation exceeding particular threshold (50, 70 and 100 mm) from more than 550 rain gauge stations in Slovakia over the periods 1951 – 2010 and 1961 – 2010, respectively. Monthly, seasonal and annual number of over-threshold precipitation incidents is analyzed. Precipitation totals exceeding at least 50 mm have a very specific position in climatological statistical analyses. In several regions of Slovakia they do not have to occur in several consecutive years, or they occur only sporadically. Moreover, these extreme precipitation totals more frequently induce insured events, especially in the cases where they are recorded in the summer as intensive rainfalls. Like other characteristics of precipitation, for which significant increasing trends were recorded in the period of the last 15 or 20 years, similar long-term tendencies are being expected in the cases of above-mentioned number of extreme daily precipitation totals.
