Issued on Tuesday morning, the warning says the well-travelled route could see snowfall of 10 to 20 centimetres between Tuesday afternoon, March 3, and Wednesday morning, March 4.
The warning stretches from Hope to Merritt and says motorists should be prepared for quickly changing and deteriorating travel conditions.
“A strong Pacific cold front will bring heavy snow to the route tonight,” the national weather agency said in its warning.
“The snow will develop near the summit late this afternoon, and then the snow level lowers to near 400 metres tonight as the front crosses the region. Total snowfall accumulations of up to 20 cm are expected by Wednesday morning.”
