Forecaster Peter Marshall says adventurers in the backcountry need to take note.
"They'll see high avalanche danger for some of the next few days and if you're heading out into those regions, you should be using extra caution and trying to avoid avalanche terrain," he said. "Sticking to low-angle sheltered slopes is the best idea."
Marshall anyone heading into the backcountry should check the Canadian Avalanche Centre website for the latest conditions.
He also warns those headed for the backcountry to go equipped with a transceiver, probe, shovel and proper training.
