This will mean certain travel routes are also hit hard, in some cases stymieing repair efforts and in others challenging motorists.
Major routes that will be affected are Coquihalla Highway from Hope to Merritt then from Merritt to Kamloops, the Okanagan Connector from Merritt to Kelowna, Highway 3 from Hope to Princeton via Allison Pass and Highway 97 from Clinton to 100 Mile House via Begbie Summit.
The national weather agency said travellers should keep others informed of their schedule and destination and carry an emergency kit and phone, as the weather in the mountains can change suddenly.
