Strong winds to bring cool change for Sunday.. gales, high waves for MB lakes Sunday night
The extended summerlike pattern of September 2009 will come to an abrupt end Sunday as a storm system tracks across Manitoba and intensifies over northwest Ontario Sunday night. Strong northwest winds on the backside of this system will draw in much cooler air over southern MB Sunday into Sunday night, with gusts of 70 to 80 km/h likely by Sunday evening over much of southern MB, with 90-100 km/h gusts possible on the eastern shores of Lakes Winnipeg and Manitoba. These strong winds will combine with high lake levels to create large waves.. possibly 3-4 metres high, which may cause problems along the exposed eastern shorelines of the lakes. In addition, the strong winds may result in tree limb damage and local power outages since most trees are still full of leaves thanks to a warm frost-free September. A similar storm system on June 27th brought 100 km/h gusts over southern Lake Winnipeg and resulted in extensive power outages through cottage country into the Whiteshell due to fallen tree limbs and power lines.
