Up to 40 centimetres of snow is expected in the Revelstoke area, Environment Canada warns.
“A Pacific frontal system will bring heavy snow to the mountain passes today and tonight,” says a warning issued Thursday morning. “Total snowfall amounts of 25 to 40 centimetres are expected by Friday morning. The snow will ease to a few flurries Friday morning as the system moves to the east.”
The warning covers the Trans-Canada Highway from Eagle Pass to Rogers Pass.
The snow is unlikely to impact Revelstoke itself, with freezing levels expected to be around 1,000 metres during the day, lowering to 900 metres at night.
Environment Canada advises against any non-essential travel. “Visibility may be suddenly reduced at times in heavy snow. Poor weather conditions may contribute to transportation delays.”
DriveBC warns of slushy and slippery roads, dense fog and limited visibility on the Trans-Canada Highway.
Parks Canada rates the avalanche danger as considerable in the alpine and moderate at treeline on Thursday; and considerable in the alpine and at treeline on Friday.
“Storm snow and strong southwest winds in the next 36 hours will increase avalanche danger,” states the bulletin. “Be aware of changing conditions.”
