Košice and Prešov are the second and the third biggest Slovakian cities situated in same basin in Eastern Slovakia. Kosice Basin is lowland-like low elevated basin along Hornad and Torysa rivers. Together in Kosice and Presov districts live around 0,5 million of people, while all Eastern Slovakia has 1,5 million inhabitants.
Severe storms are in this part of Slovakia more frequent such as in western and some parts of central Slovakia. Mainly large massif of Slovenské Rudohorie and Nízke Tatry westward from Košice and Prešov are very stormy and storms are traditionally shifting to east from these mountainous parts of Slovakia, towards densely populated areas.
However, for tornadoes, lowland conditions are needed, tornado can´t create above hills or mountains.
