Another weather system anticipated for this evening could potentially bring an additional 80 to 150 mm of rain in southwest and western Manitoba, and in eastern Saskatchewan over the next 48 hours. The Assiniboine, Qu'Appelle and Souris rivers and their tributaries could be affected.

Meanwhile, overland flooding is being reported from areas across the Assiniboine River. A number of smaller rivers, including the Little Saskatchewan River, are above flood stage and low-lying land near the river is affected. 

Flooding of low-lying areas is expected for most portions of the Assiniboine River and its tributaries. However, water levels are expected to remain below flood protection levels at most locations along the Assiniboine and Souris rivers. 

Operation of the Portage Diversion may be required later this week to limit flows in the lower Assiniboine River to 10,000 cubic feet per second.

The Shellmouth Reservoir is expected to handle the potential inflow increase due to the forecast precipitation system.  

Property owners are advised to take precautions as water levels could quickly rise significantly in these areas.
