Officials said one twister hit an area west of the town of Assiniboia, a second touched down near the village of Fillmore, a third hit an area southwest of the town of Grenfell and the fourth was caught on tape by a storm chaser just east of Regina near the Town of Balgonie.
Greg Johnson, a dedicated tornado hunter, was following a late afternoon storm that roared through southern Saskatchewan Tuesday.
He said the twister touched ground for about six or seven minutes on a farm property about 10 kilometres south of the Trans-Canada Highway near Balgonie.
"We watched it rip through a farmyard," Johnson said. "[It] kicked up a lot of debris. We stopped in at the home and fortunately everything was OK. The house was spared but a number of the outbuildings were destroyed."
According to Environment Canada, a spotter for the agency reported that a tornado touched down south of Balgonie, which is 25 kilometres east of Regina, around 4:55 p.m. CST.
Among the people who spotted the twister was Kathy Rosenkranz, who lives about 36 kilometres east of Regina.
"Around 5 p.m, the sky became very active as a system was coming towards our acreage near Davin," Rosenkranz told CBC News. "Some clouds started swirling in the sky, just across our grid road and we could see a funnel forming from this."
Rosenkranz snapped a picture of the twister.
"Luckily the wind was pushing this swirling cloud northeast as it went past our place and stayed on the ground for many minutes, hitting just open field."
The tornado was part of an intense weather system that generated thunderstorm and tornado warnings for a wide swatch of Saskatchewan.
It was the latest sighting in a summer season that has produced several violent weather episodes.
