Avalanche Summary

No new avalanches were reported on Tuesday. Over the long weekend, there were numerous reports of wind slab avalanches being triggered. Check out the many MIN reports here for some great observations. In general, small to large (size 1 to 2) wind slabs were triggered in steep alpine terrain. They were 10 to 30 cm deep and on southwest to northwest aspects.

Snowpack Summary

Snow surface conditions are variable. At higher elevations, wind slabs may exist in lee terrain features from recent snowfall and strong winds blowing in variable directions. These slabs may overly weak faceted grains. In sheltered areas, around 10 to 20 cm of low-density faceted snow may be found, possibly sitting on weak surface hoar and a smooth melt-freeze crust. On southerly slopes, moist snow or a thin melt-freeze crust is to be expected. The remainder of the snowpack is generally well-settled.
