A tornado injured at least five people and damaged buildings in eastern Colorado on Saturday, according to authorities.
The Yuma County Sheriff's Office said its deputies would be assessing the damage and coordinating with first responders after the half-mile-wide twister touched down at the north edge of the city of Wray.
Four structures suffered "significant" damage and five people suffered "minor injuries," according to the sheriff's office. It added that the storm knocked down around 40 electric poles.
Several other tornadoes were reported in the area of Wray, a town of around 2,300 about 12 miles from the Nebraska border.
The largest tornado followed U.S. 385 north of the town, throwing down power lines and strewing debris across the highway.
