Avalanche Summary

Snowpack Summary
The BYK Region received between 15-30 cm of storm snow over the weekend with the deeper amounts closer to the divide. This storm snow sits on a mix of facets, surface hoar and and thin sun crusts (Jan 30 layer). Strong winds during the storm will have created fresh windslabs in the alpine and open areas at treeline. The mid-pack is generally weak and faceted with an old crust and depth hoar near the base.
Weather Summary
Tuesday will be continued cold (treeline highs of -20) with scattered clouds and only very light precipitation. Winds are forecasted to be light to moderate from the south.
Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
Problems

Moderate to strong winds on Saturday have redistributed the storm snow and created wind slabs in the alpine and some treeline locations. The bond to the old (Jan 30) surface remains uncertain, so assess conditions locally.
