Spring may have sprung but it won't feel like it tomorrow, at least.

Environment Canada has issued a special weather statement for the mountain passes surrounding the valley including the Coquihalla Highway - Hope to Merritt and Highway 3 - Hope to Princeton via Allison Pass.

You're advised to watch out for an abrupt transition back to winter conditions late Thursday for the Coquihalla, Okanagan Connector and Highway 3 - Hope to Princeton via Allison Pass.

A frontal wave will move across southern B.C. on Thursday. The warm front will bring some rain and rising freezing levels Thursday morning. However, the cold front will be quite potent and arrive as early as Thursday afternoon.

The passage of the cold front will result in a sudden change in precipitation from rain to heavy snow over the highways resulting in reduced visibility and possible rapid accumulation of snow. A rapid drop in temperature and snow level will also accompany the cold front.

Travellers are advised to exercise caution if travelling late Thursday and to be aware of rapidly changing road conditions.

Weather in the mountains can change suddenly resulting in hazardous driving conditions.
