Most of Canada is under warnings from Environment Canada on Tuesday, principally due to two weather systems. A messy winter snow and ice storm is heading toward Ontario, with most of the Prairies and northern parts of Canada under extreme cold and winter storm warnings.
A double-barreled storm, fuelled by an “Alberta Clipper” and then a “Colorado low,” is expected to bring high ice accumulation totals to the southern half of Ontario and higher snow totals to the northeast… The Alberta Clipper, a low-pressure storm system that moves from the west, will impact northern Ontario communities overnight on Tuesday. The system from Colorado brings low-pressure Wednesday evening, to the southern half of the province with snow and freezing rain expected. As the two systems head to Eastern Canada, many provinces including B.C. and the Prairies are buried under snow and subject to extreme cold warnings issued by Environment Canada.

On the West Coast, “winter is not over,” said Armel Castellan, warning preparedness meteorologist with Environment Canada said to CTV News Vancouver as the agency issued winter storm warnings across the B.C. interior.
The Pacific frontal system is expected to bring snow accumulation of 20 to 25 centimeters to the Fraser Valley, Okanagan Valley, East Columbia, and Fraser Canyon. The storm is expected to taper off by Tuesday afternoon, but “light snow will continue through tonight,” the Environment Canada website reads. Environment Canada urged residents to postpone non-essential travel along all highway mountain passes in the area.
