Tornado Alley
States such as Missouri, Iowa, Minnesota, Wisconsin, Illinois, Indiana, and western Ohio are sometimes included in Tornado Alley. Research suggests that tornadoes are becoming more frequent in the northern parts of Tornado Alley where it reaches the Canadian prairies.
Tornadoes of 2016
Scattered tornadoes occurred across the states of North Dakota, Minnesota, Iowa, and Michigan during a two-day period. Most of these tornadoes remained over open country, though a few caused damage. On August 27, a large EF1 tornado tossed small trailers, destroyed a small barn, and snapped and uprooted many trees near Emerado, North Dakota. An EF3 tornado near Hillsboro ripped the roof and exterior walls from a well-built house, severely damaged a grain elevator, and destroyed half of a metal building. The following night, a multiple-vortex EF2 tornado snapped numerous trees and power poles, completely destroyed a barn, and caused considerable roof and wall damage to two homes near Gary, Minnesota. Eight tornadoes were confirmed in total.
