Environment Canada says a "series of upper disturbances combining with cold arctic air" will result in significant snowfall to parts of B-C's northern and central Interior.
It says up to 25 centimetres of snow is expected in the region by tomorrow afternoon.
The agency says the wintry weather in the region began yesterday and continues today, with further intensification possible overnight.
Environment Canada is urging caution for anyone travelling in the region, saying visibility may be suddenly reduced for drivers and surfaces may become difficult to navigate as snow accumulates
