For the second time in less than a week, Environment Canada has issued a Snowfall Warning for Highway 3, Paulson Summit to Kootenay Pass.
Environment Canada said higher elevations can expect total snowfall accumulations of 15 cm beginning Friday morning and through to the evening.
"A Pacific frontal system will sweep over B.C. Interior on Friday," Environment Canada said.
"Heavy snow from the system will start over Trans-Canada Highway — Eagle Pass to Rogers Pass in the morning and spread to Highway 3 — Paulson Summit to Kootenay Pass in the afternoon.
"The snow will taper off to a few flurries early in the evening as the front moves southward away from the region."
Friday morning, Environment Canada added to the Snowfall Warning that a winter storm will also move into the region Saturday night, giving heavy snow and strong winds to the West Kootenay/Boundary region.
Environment Canada advises drivers to be prepared to adjust driving with changing road conditions as visibility is most likely to be reduced while driving.
"Turn on your lights and maintain a safe following distance," Environment Canada said.
"Weather in the mountains can change suddenly resulting in hazardous driving conditions."
The website Shift Into Winter reminds drivers to be prepared before trips and to adjust to winter driving behaviour and use winter tires and chains.
