Avalanche Summary
There is now new avalanche activity to report.
Snowpack Summary
5-10 cm of new snow has accumulated over a crust that varies in thickness and elevation throughout the forecast area. In the Dogtooth Range, this crust thins in the alpine and becomes breakable.
Below the fresh snow and mentioned crust, there is around 50 cm of moist snow with multiple crust and facet layers beneath. The base contains weak faceted grains and depth hoar, which will be continue to be monitored for reactivity.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
Problems
Wind Slabs
Watch for reactivity in wind-affected features where fresh snow has fallen.
Aspects: North, South, South West, West, North West.
Elevations: Alpine.
Likelihood

Deep Persistent Slabs
Multiple weak layers in the snowpack remain a concern. Most specifically facets on crust near the base of the snowpack. Be especially cautious in areas where the recently formed crusts near the surface are not supportive.
Aspects: All aspects.
Elevations: Alpine, Treeline.
