Calgary and much of southern Alberta was plunged back into the depths of winter Friday, as a storm system moved over the province and blanketed it with snow. "Travelling in southern Alberta tonight and tomorrow is not recommended due to blowing snow conditions," she said. Then near the mountains in Montana and Wyoming, more moisture is being added, increasing the snow in the southern Alberta region. Much of southern Alberta is under either a snowfall or winter storm warning. Environment Canada has placed southern Alberta under weather warnings on March 13.
