A low-pressure system from Montana is expected to bring 20-50 mm of rain to southwestern Saskatchewan, which could cause overland flooding.

Environment Canada scientist Christy Climenhaga says some southern communities have already received a significant amount of rain over the last 24 hours. For example, Elbow received 46 mm, and Regina has seen nearly 40 mm, so an extra dousing could bring cause flash floods and water pooling on roads. Localized flooding in low-lying areas is also a possibility.

She adds that this is unwelcome news for farmers attempting to harvest the last of their crops.

“This amount of rain is not the best outcome at this time of year for farmers who are trying to get their harvest off the field, so if you are in that southwest part of the province, that will be something to think about before we get to a little bit of clearing and a bit of relief in the next day or so.”

Residents in areas like Swift Current, Shaunavon, Maple Creek and Val Marie are reminded to stay off the roads if visibility is poor due to heavy rainfall, and to do what they can to prevent basement flooding.

“It’s important to remember not to drive through water that you don’t know how deep it is, because you can get stuck. Also, you’re looking at a risk for basements. (You should) make sure sump pumps, sump pits, and sewer valves are working so you can reduce the chances of flooding in your own home.”

The system should start moving out of the region and into the north-east part of the province by this evening.
