UPDATE: 11:43 p.m.
Besides snow, slush and ice on the Coquihalla, drivers are also being warned of delays.
Motorists can expect delays near the Box Canyon chain-up area on Highway 5 due to semi-trucks spinning out.
Slushy and slippery sections are also anticipated from exit 256, Coldwater Road to Merritt.
It may be another good day to avoid driving over mountain passes.
Environment Canada is reporting that a strong Pacific frontal system is rapidly approaching the South West coast of B.C.
Periods of snow will begin falling on highway passes this morning, and become heavy at times this evening and through tonight. The Coquihalla Summit could receive 25 to 35 centimetres snowfall accumulation, while Allison Pass and Kootenay Pass could receive 20 to 25 cm of snowfall accumulation.
Snowfall should ease early Thursday morning as the system moves through to the east.
The weather agency reminds motorists to be prepared to adjust one’s driving with changing road conditions. Rapidly accumulating snow could make travel difficult over some locations. If visibility is reduced while driving, turn on the lights and maintain a safe following distance.
