| ABSTRACT | Abstract: This paper presents the research results of synoptic and mesoscale weather conditions which created a favourable meteorological environment for a waterspout development in Tivat ( on June 9, 2018, in the early morning hours (around 01 UTC, that is, 03 СЕТ). Also, an analysis of atmospheric sounding measurements, radar and satellite images, has been carried out. Based on field survey analysis, damage estimates were undertaken to assess the tornado category by the Fujita scale (F-scale). Based on synoptic material analysis, there was too warm surface air which suddenly lifted up and cooled, with the atmospheric instability in the upper layers, that is, sufficient moisture and latent heat. Therefore, forecasting material indicated an abrupt development of thunderstorm clouds-cumulonimbus cloud (Cb) and a possible severe weather event. The forecast was almost completely accurate, which was proved by the analysis of SYNOP reports, satellite images and by the field damage estimates. Synoptic type for this situation was CLOSED-SW and was determined by a detailed examination of circulation on the AT 500 mb map, as well as by the position and characteristics of isobaric features in the upper levels and those at the surface. Further investigations of meteorological environment which leads to the development of waterspouts in the Adriatic Sea are needed in order to find more precise correlation between presented thermodynamic parameters and mesoscale synoptic situation.
