Environment Canada warns if you don't have to travel this evening, you might want to postpone highway driving until conditions improve.
The weather office has issued a snowfall warning for all of the upper elevation highways - amounts will vary depending on the location - but as much as 75 centimetres could fall in some areas.
Heavy snow is expected on the Coquihalla between Hope and Merritt - on Highway 3 through the Allison Pass and from Paulson Summit to Kootenay Pass - and on the Trans-Canada from Eagle Pass to Rogers Pass.
Environment Canada says hazardous winter driving conditions could develop including highways rapidly filling with snow and reduced visibility.
There's more information about the impending snowfall on Environment Canada's webpage.
