Kernpunkte

Strong winds at upper elevations may have created small pockets of wind slab that a person could trigger.

In sheltered areas, soft snow may offer decent riding conditions.

    You may find pockets of wind slab at treeline and above. Watch for stiff, wind-loaded snow on ribs and gullies, especially where it sits over a weak, sugary layer near the base of the snowpack

Avalanche Summary

No new avalanches reported. If you are out and about in the mountains, please consider posting your observations to the MIN.

Snowpack Summary

Strong winds and blowing snow may have formed isolated wind slabs at treeline and above. The upper snowpack is variable, with wind-affected surface snow in open terrain and softer snow in sheltered areas. This overlies a crust that formed in mid-November. The lower snowpack consists of multiple crusts, and in some areas, a layer of weak, sugary facets can be found near the ground.

Total snowpack depths are roughly 60 to 80 cm, tapering quickly at lower elevations.

In many areas, especially below treeline, there is not enough snow to smooth out surface roughness or reach the threshold needed for avalanches.

Terrain and Travel Advice
