Avalanches are decreasing in likelihood, but it still may be possible to trigger wind slabs in isolated pockets in the alpine. This is a great MIN report from the South Columbia region on Wednesday that helps to paint the picture of these wind slab avalanches.

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 70-140 cm at treeline elevations.

A week of cold temperatures has been decreasing the strength of the upper snowpack, except in isolated areas where it has been drifted into wind slabs in the alpine. These slabs could be more reactive where they overly a weak layer of surface hoar (feathery crystals) that formed on a crust. 

A variety of crusts from late October are buried deeper in the snowpack (down 50 to 100 cm). Generally, the prolonged inactive weather pattern has improved snowpack stability in the short term.
