Environment Canada says an arctic front will bring snow and strong winds between Hope and Merritt on the well-travelled route.
Light snow is anticipated for Saturday, though that’s expected to intensify into the evening and overnight, with 20 cm projected before easing on Sunday afternoon.
“Accompanying the arctic front, periods of strong outflow winds will result in low visibilities tonight due to blowing snow,” said the national weather agency.
