Environment Canada has issued a number of snowfall warnings for Interior highways.
The Coquihalla, between Hope and Merritt, is expected to get between 30 and 40 cm of snow.
It's all a result of an "unseasonably cool spring storm," according to the national weather agency.
"Snow will fall today at the highest elevations but will fall in earnest beginning tonight," reads the online bulletin. "As a cold front sweeps across the province on Sunday, an unsettled air mass will result in brief but intense bursts of flurries over the highways with sudden reduction in visibility due to heavy snow."
The spring storm has prompted Environment Canada to issue a special weather statement for the Okanagan Connector. Snow levels will be unseasonably low, hovering between 1,100 and 1,400 metres. Drivers should expect adverse driving conditions: rain in lower elevations and snow in the passes.
A snowfall warning is also in effect for the Trans Canada Highway, from Eagle Pass to Rogers Pass. Environment Canada is predicting between 20 and 30 cm of snow will fall on that highway. The same goes for Highway 3, Paulson Summit to Kootenay Pass.
