Crashed Semi flipped on its side blocks South Dakota Interstate

Storm chaser Justin Frantzen captured this footage of a truck blown over in wind gusts of 80 mph during storms over the northern plains.

Frantzen said: "I was inside the storm that was packing strong severe thunderstorm winds of 75-80 mph between Hurley and Viborg SD! 285th street was my location when I came to the semi...Got out after the rain had somewhat subsided and assisted to help the male driver out! He was unharmed! "
