A typical squall line with heavy rainfall (100 mm in 24 h) occurred on 25 October 2014 in Antalya, southwest Turkey. There was serious damage on residential areas, it has affected the transport and has a negative impact on daily life. People sitting on ground floor were evacuated and many cars was flooded water. This study examined factors cause severe rainfall seen in Antalya. Squall line is considered to be one of the reasons for the heavy rainfall and this is supported by the satellite and radar observations. Also synoptic conditions were investigated in terms of global instability indices, weather stations observations of the Turkish State Meteorological Service, convective available potential energy (CAPE) and sounding (the vertical profile of temperature and variables in the atmosphere over one goegraphic location). In the study performed, 280 mm of rainfall occuring in the 8-hour period has been found the result of the squall line.
