Much-needed snow is falling across the B.C. South Coast and Southern Interior mountains Sunday. The snowfall comes after the province reported the snowpack is at 61 per cent of normal with the South Coast mountains recording only 30 to 47 per cent of seasonal averages. This well-below-normal snowpack is raising concerns about drought heading into the spring and summer months. Ten to 20 centimetres of snow is expected in the mountains Sunday through Monday morning. …A snowfall warning is in effect for Whistler, Central and Northern Okanagan, South Thompson, West Columbia and East Kootenay regions.
