SEVERE WIND WARNING, HIGH WATER ADVISORY ISSUED FOR INTERLAKE REGION



A severe wind warning and high water advisory has been issued for the Interlake region by Manitoba Infrastructure and Transportation’s Hydrologic Forecasting and Water Management Branch.

Environment Canada has issued both heavy rainfall and high wind warnings for this afternoon and tomorrow for the Interlake region.  A low-pressure weather system is tracking east to northeast across central Manitoba and the Interlake with potential for strong winds and heavy rains.

Strong north to northwest winds at 30 to 70 kilometres per hour are expected and a severe wind warning is in effect for the south basins of lakes Winnipeg, Manitoba and Winnipegosis.  These forecast winds have the potential to cause two to three feet (ft.) of wind setup and significant wave action.  People living close to lakeshore areas, especially in the southern basins, are advised to be vigilant and take necessary precautions.

Current lake levels are:

  • Lake Winnipeg, 715.01 ft., (2011 peak was 716.9 ft.);
  • Lake Manitoba, 812.81 ft., (2011 peak was 817.15 ft.); and
  • Lake Winnipegosis, 833.63 ft., (2011 peak was 834.82 ft.).

In addition, heavy rains of 50 to 70 millimetres are likely over portions of the Interlake and in areas east of Lake Winnipeg.  The rain will taper off in these areas after midnight tonight.  Localized overland flooding may occur in areas that receive heavy rains.  River levels in the region will likely rise but are expected to remain within banks.  Areas that may be affected by these rains include Grand Rapids, Arborg, Hecla, Fisher River, Gypsumville, Ashern, Poplar River, Berens River, Little Grand Rapids, Bloodvein, Atikaki, Bissett, Nopiming Provincial Park and Pine Falls.

The Hydrologic Forecast Centre will closely monitor weather conditions and provide further updates if conditions change.
