The National Weather Service says a large tornado in Kansas that was on the ground for nearly an hour and a half missed a small town by about a mile.

Meteorologist Chad Omitt says the tornado formed just after 7 p.m. near the Ottawa County community of Niles. He says it stayed on the ground continuously as it moved into Dickinson County.

Omitt says it looks like “the heart” of the tornado was just about a mile south of the town of Chapman at one point. He says estimates are that the twister was a quarter- to a half-mile wide at times.

Radar suggests the tornado dissipated around 8:35 p.m.

Authorities are assessing damage, but there were no immediate reports of injuries.

Weather service crews will survey the area tomorrow.
