Global News
If you're planning to head to the mountains this weekend, check the avalanche forecast and go prepared.
Avalanche Canada has issued a warning for parts of Alberta including Banff and B.C.
Warm temperatures and lots of sunshine are expected for the coming weekend, which will have a destabilizing effect on the snowpack.
This warning is in effect immediately and will apply through to the end of Monday, Jan. 24, Avalanche Canada said.
The special warning applies to the following regions: Banff, Yoho, North and South Columbias, Purcells, Kootenay Boundary, and in Glacier, Banff, Yoho, and Kootenay National Parks.
It also applies to an area within the Sea-to-Sky and South Coast Inland regions, from Squamish to Pemberton.
“There are persistent weak layers in the mountain snowpack across most of southern BC and western Alberta,” explained James Floyer, forecasting program supervisor for Avalanche Canada.
“This special warning targets regions where these layers have proven to be an issue. The combination of this snowpack structure and higher temperatures will make natural and human-triggered avalanches much more likely.”
Avalanche Canada said there have been several close calls reported recently, with many large avalanches running the full extent of their paths.
