A tornado watch has been issued by Environment Canada for Estevan and area.
"We have a low-pressure system that is sitting in southeastern Alberta and Montana," explained John Paul Cragg with Environment Canad, "and that low-pressure system will be the focus of storms that will form later this afternoon in Saskatchewan and continue through into the evening and potentially into the overnight period."
"That low-pressure system has a warm front and a cold front and that warm front is hanging down across the province right now and through southern Saskatchewan and then into Estevan. As that low progresses over the afternoon and evening, there's a really good chance along the cold front that storms will form and be severe. But before that, the warm front that is sitting through Estevan could spark some thunderstorms."
He added that they are not sure if thunderstorms will form or not but if they do, they have the potential to become severe with a chance of a tornado along with hail, heavy rains and strong winds.
"As the low progresses across the province later this evening, it will also bring some thunderstorms. That should pass through Estevan anywhere between 8 pm and 11 pm this evening."
"There's really two threats to the Estevan area. One, there's less of a chance of it developing but if it does, things could be severe and that's late this afternoon and early this evening. And again, with the cold front later this evening."
The storms expected later this evening have a risk of very strong winds, hail, and heavy rain, and less of a risk of a tornado late this evening.
"With all summer severe weather, it's not necessarily going to be the case that your particular community gets affected. A watch means stay vigilant, nothing is occurring yet and a warning means take cover because something is coming and threatening your area. Right now it's only a watch for the Estevan area."
