Good

Weather Forecast

Cloudy skies tomorrow with temps similar to today. No snow. The change in wind is important. They will pick up and swing to the a northerly flow. Wind chill is worth some consideration.

Avalanche Summary

Unlike the neighboring areas, the windslab from the last snow are thin and inconsequential. The odd pocket of very small, reactive slabs were noted today. More of a concern for climbers. No significant avalanches noted.

Snowpack Summary

Variable is the best word to describe the snowpack right now. Surface snow is either exposed sun crust, wind slab,  hard slab(hard to hold a ski edge) or a skiff of snow from last week's flurry. Sheltered, north aspects still held dry snow. As for the midpack, in the alpine and treeline it is supportive for ski traffic. Below treeline it is still weak, but supportive in most areas. No change in the lower layers.

Problems

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
