Manitoba Infrastructure and Transportation’s Hydrologic Forecast Centre has issued a high wind warning for the Lake Manitoba south basin, from the Lynch’s Point to Twin Lakes Beach and on the entire south basin of Lake Winnipeg.
Tomorrow’s winds could increase the water level by three to five feet and will produce significant wave action on downwind shorelines.
- There is also a moderate-high wind warning on the south shorelines of Dauphin Lake, Lake Winnipegosis and on Lake Manitoba in the narrows area as well the eastern shoreline of the south basin, north of Twin Lakes Beach. Tomorrow’s winds could increase the water level by two to three ft. and will produce considerable wave action on downwind shorelines.
- The southwest winds today will shift to come out of the northwest tomorrow, and could increase water levels and result in significant wave action on the south and east shorelines of the lake.
Environment Canada has issued a rainfall warning for much of western Manitoba:
- A large and intense low-pressure system located over the Manitoba Interlake area continues to produce moderate to heavy rain at times across much of southern Manitoba and southeast Saskatchewan. This system has brought exceptionally heavy rain to parts of the warning area over the past 24 to 48 hours with amounts of 100 to 200 millimetres being reported along the Manitoba-Saskatchewan border from Yorkton through Moosomin to Redvers into the Melita and Virden areas. This system will continue to produce locally heavy rain at times this evening before gradually easing overnight into Monday. A further 15 to 30 mm is possible tonight and an additional five to 10 mm Monday before the rains finally taper off Monday night into Tuesday.
- Heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible. Watch for possible washouts near rivers, creeks and culverts.
