Avalanche Summary
No significant avalanche activity has been reported in the last couple of days.

Snowpack Summary
High freezing levels produced moist surface snow up to 2000 m on Friday. As temperatures cool a crust will form.
Surface snow has been redistributed by recent winds in exposed terrain. In alpine areas, up to 10 cm of low-density snow overlies various firm layers. The mid snowpack is generally consolidated and sits above a weak, facetted lower snowpack.

Terrain and Travel Advice
- Wind slabs are most reactive during their formation.
- Pay attention to isolated alpine features as well as cross-loaded features at treeline.
Problems
Wind Slabs
Where dry snow has prevailed through warm temperatures, wind slabs may lurk in exposed alpine terrain. Cautiously approach slopes adjacent to ridges or rocky, shallow terrain.
