Avalanche Summary
No recent avalanche observations reported.
No persistent slab avalanches have been reported since early February.
If you are traveling in the mountains consider posting to the MIN.
Snowpack Summary
Up to 10 cm of new snow accompanied by strong southwest wind may build new wind slabs Wednesday. It sits over firm wind-affected surfaces in exposed areas or softer, faceted snow in sheltered terrain. A crust may exist on steep solar aspects.
A weak layer of facets and a crust from early December is buried 60 to 100 cm deep. This layer exists on all aspects up to 1750 m. This layer has not been active in producing avalanches or test results in several weeks and is generally not a concern at this time.
At the highway elevation, the snow depth is 120 cm, and in the alpine exceeds 200 cm.
