A tornado watch has been issued for the southeast, due to a low pressure system warning in Montana.

"Moisture is moving into southern Saskatchewan, helping to create an environment that can produce thunderstorms," said Alyssa Peterson, Meteorologist with Environment Canada.

Peterson said that tornado watches are issued when conditions are favourable for thunderstorms that could possibly produce a tornado, but a tornado warning is issued when conditions are imminent or occuring. 

"So, if we see on radar that there's rotation in the storm and we see that it could be producing a tornado, or from spotter reports, we issue a warning," she said.

She said the watch is currently in effect due to these conditions from Montana moving up into the area.

"So, the tornado watch is out because we think the conditions are favourable that severe thunderstorms that do develop in the area could possibly produce a tornado, but whether or not Estevan or Weyburn are going to see a tornado really depends on the strength of the storm if there's a storm that goes through that area," she said.

"The watch is not a guarantee that there will be severe weather in the area," she added.

In the event of a tornado, or if a tornado warning is issued for your area, it is recommended you take the following actions: Go indoors to a room on the lowest floor, away from outside walls and windows, such as a basement, bathroom, stairwell or interior closet. Leave mobile homes, vehicles, tents, trailers and other temporary or free-standing shelter, and move to a strong building if you can. As a last resort, lie in a low spot and protect your head from flying debris.
