Ontario is bracing for multiple rounds of snow this week as several weather systems combine with the Great Lakes to create challenging conditions. Travel delays and deteriorating conditions are expected, with some areas at risk of receiving 30 to 40+ cm of snow, particularly in the hardest-hit regions.
A stalled low-pressure system over Lake Superior will bring heavy snow to areas downwind of the Great Lakes, while another persistent low near Lake Ontario will continue to cause unsettled weather through Tuesday.
