Environment Canada said Tuesday that further investigation of a tornado that touched down near Nanton, Alta., on Sunday has unearthed evidence the twister was more powerful than first thought.

“Following an investigation of damage sustained to a farm southwest of Nanton by the Northern Tornadoes Project and storm-spotters in the region, the rating of the tornado has been upgraded,” the weather agency said in a new weather summary posted to its website Tuesday afternoon.

The Nanton-area tornado has now been preliminarily rated as an EF-1 tornado that reached an estimated wind speed of 150 kilometres per hour.
