Environment Canada has issued a special weather statement for a number of mountain highways, including the entire Coquihalla Highway.

It is calling for between 2 and 5 centimetres of snow starting Thursday night into Friday morning, and possibly early Saturday of the May Long Weekend.

Similar statements are also in place on the Okanagan Connector, the Trans-Canada between Eagle and Rogers Pass, Highway 3 between Hope and Princeton as well as between Grand Forks and Creston, and Highway 97 between Clinton and 100 Mile House.

“An upper low will bring a cool airmass to higher elevations of the BC Interior late Thursday into this long weekend,” Environment Canada said. “Colder air along with precipitation means the mountain passes can expect a dusting of snow overnight Thursday and possibly overnight Friday.”

“For Allison Pass, the Coquihalla Highway and the Okanagan Connector, snow can be expected above 1100 metres. At Rogers Pass, snow is expected above 1300 metres and at Begbie Summit snow is anticipated above 1000 metres. For Kootenay Pass, snow is expected above 1400 metres.”

Drivers are being told to check Drive BC for the latest road conditions as winter tire requirements in B.C. were lifted on May 1.

“Transportation routes may be impacted,” the statement said. “Travellers should be prepared for rapidly changing weather conditions. Weather in the mountains can change suddenly resulting in hazardous driving conditions.”
