it snapped hardwood trees in a shelterbelt and blew over and
destroyed an animal shelter. The tornado then dissipated about

This third tornado also moved south and about six miles south of
Ruso it destroyed three small wooden granaries, damaged farm
equipment by flipping over a large seed cart attached to an air
seeder, tossed round hay bales and flipped anhydrous tanks. The
tornado then dissipated at about 550 PM about 8 miles south of Ruso.
