Avalanche Forecast

Low - Uncertainty is due to the limited number of field observations.

Wednesday night: Mostly clear skies, alpine temperatures -18 C, strong east/northeast winds, no significant precipitation expected.

Thursday: Mostly sunny, alpine temperature -15 C, light easterly wind, no precipitation.

Friday: Mostly sunny, alpine temperature -10 C, light easterly wind, no precipitation.

Saturday: Mostly sunny, alpine temperature -8 C, light variable wind, no precipitation.

Observations are limited this time of year, so there is a fair bit of uncertainty about the extent of current avalanche activity. The most likely place to trigger avalanches right now is where the wind previously drifted snow into wind slabs. If you see anything while out in the field, please consider sharing that information with us and the backcountry community via the Mountain Information Network.

Snow line sits around 1200 m, and snow depths range from 90-160 cm at treeline elevations.

With this week's clear, cold, and dry weather, the weekend storm snow is likely losing strength, except where it has been drifted into wind slabs in the alpine. Variable winds have drifted the 20-60 cm of recent snow into wind slabs that may still be possible to trigger. In some areas, this snow sits on a crust with surface hoar (feathery crystals). This "Nov. 23 crust" has produced sudden and repeatable results in snowpack tests.

A variety of crusts from late October are buried deeper in the snowpack (down 70 to 140 cm). The inactive weather pattern this week also promotes a decreasing trend in reactivity for these layers.
