Danger ratings in Banff, Yoho and Kootenay National Parks for Friday are considerable at the alpine, treeline and below-treeline levels.

A statement on the organization’s website said the snowpack throughout the region “has a weak base and remains suspect.” It added natural avalanches are possible and human-triggered slides are likely.

In addition, warmer temperatures on Friday could promote “failures of large cornices” that could trigger deeper instabilities.

Avalanche Canada is warning anyone headed into the backcountry to carefully evaluate the snowpack and use caution in determining routes. Forecasters also warn to be wary of slopes that have not previously avalanched.
