Kernpunkte

Its a mixed bag of wind effect, facets and powder at treeline and above. Watch for pockets of wind slab or heavy sluffing in very steep terrain.

    A mix of old and new wind slabs have been found on various aspects that in the short term will be something to watch for in the terrain.

    A sustained period of cold weather has driven the faceting process in the upper snowpack creating weak, dry surface snow. In steep terrain, these are sensitive to small natural and human triggers and can quickly gain enough mass to affect travelers.

Weather Forecast

A day and a half of light snow and clouds. Continuing cold temps that become tolerable through the day.

Snowpack Summary

Great variability is found in the snowpack in the alpine and near treeline. Deep facets, windslab, suncrust, and snow depths from 0-200+ cm are all present. Midpack surface hoar can be found in isolated locations at treeline and below, and is producing hard but sudden test results. A weak basal snowpack exists in many areas.

Avalanche Summary

No avalanches were reported today.
