Environment Canada has issued a tornado warning for the Maple Creek-Shaunavon-Cypress Hills and Val Marie regions.
The weather bureau says it is tracking a severe thunderstorm leading to a tornado with noxious winds, large hail and could result in heavy local rains.
As of 4:30 p.m. on Tuesday afternoon, the southwest corner of the province was the only part where severe weather occurred, but that could change later in the night.
