If you are planning to drive out of the valley today, be careful.
Environment Canada has issued a snowfall warning for a number of mountain passes, saying 20 to 30 cm is expected to fall.
"In the wake of a Pacific frontal system an unstable southwest flow will continue to give snow to southern highway passes," reads a statement from Environment Canada.
"Total snow accumulations of 20 to 30 cm are expected over Coquihalla Summit and Allison Pass. The snow will taper off Wednesday morning."
Visibility may be suddenly reduced at times in heavy snow. If visibility is reduced while driving, turn on your lights and maintain a safe following distance.
