A tornado that touched down in the town of Krum, Texas, was confirmed by the National Weather Service, Denton County Sheriff’s Office told NBC News, though the exact location and severity of the damage were not known. Nor were any injuries reported.

Storm spotters and Doppler radar saw the developing tornado 3 miles southwest of Krum as it moved eastward toward the city of Denton, which saw golf-ball sized hail earlier in the day.

The weather service also issued tornado warnings Thursday for several areas in Missouri, part of the same storm system that forecasters said could be the first significant tornado outbreak of the season.

An alert was issued for people living in southern Benton and northern Hickory counties at about 5:15 p.m. ET with residents asked to “take cover at this time.”
