FORT ST. JOHN -- Environment Canada has issued a snowfall warning for the Pine Pass section of Highway 97.

Heavy snow is expected on Thursday morning. A total of 15 to 20 cm is expected throughout the day.

Environment Canada says a frontal system moving over the region has produced heavy snow to the area overnight.

Heavy snow will continue early this Thursday morning before changing to rain showers later this morning.

Be prepared to adjust your driving with changing road conditions. Rapidly accumulating snow will make travel difficult.
