Storm chaser Marko Korošec

These astonishing photos were taken at the heart of Tornado Alley in the Great Plains of the United States.

Storm chaser and professional photographer Marko Korošec, 34, from Sežana, Slovenia, is also a meteorologist and a supervisor for Slovenia's Road Weather Information System.

Korošec often travels to the hurricane hot spot in America for a few weeks between May and June, when the storms are most severe and the tornado season peaks.

Korošec's hunt for a sensational storm has taken him all over the United States, Croatia, Italy and the coast along the Adriatic Sea, hoping to catch one on a flat field, where they are at their most formidable. (Caters News)
