The Hydrologic Forecast Centre of Manitoba Infrastructure reports the potential for significant precipitation and heavy wind, ending early Wednesday, could produce overland flooding and high water conditions.
The areas of concern are the northern regions and southeast Manitoba. These areas could receive up to 60 millimetres of precipitation. The risk is low in most other portions of the province.
For the northern areas, including the Saskatchewan River and the Churchill River watersheds, there is a higher probability of receiving 50 to 70 mm of precipitation. Base flows and soil moisture are high in these areas as some areas are already reporting very high water levels.
For southern and southeast basins, including the Whiteshell lakes area, could receive 20 to 40 mm of precipitation. Most Whiteshell lakes are at the optimum level for this time of the year. Other southern and southeast areas could receive near 20 mm, with low risk of overland flooding.
The Red River basin could receive up to 50 mm of precipitation. However, there is no high water concern as the Red River has capacity.
