An incoming Pacific warm front is going to make travel difficult over the next day or two.

Environment Canada has issued a snowfall warning for the Coquihalla Highway (Hwy 5) and continued a previous warning for the Okanagan Connector (Hwy 97C) and the Allison Pass (Hwy 3).

Tonight, the Coquihalla could see up to 10 centimetres of snow and the snowfall will continue into Monday, affecting all three routes.

"The snow will also spread further inland to impact the Okanagan Connector between Merritt and Kelowna and Highway 3, Allison Pass between Hope and Princeton," explains the snowfall warning.

"Accumulations of 10 to 15 cm are expected during the day Monday and an additional 10 to 20 cm is likely Monday night."

In total, up to 30 cm of snow is expected and visibility could also be an issue at times at higher elevations.

If you can postpone travel until Tuesday, it's advised, but you can stay up to date on the latest highway conditions and closures by visiting the DriveBC website.
