Lo esencial

Continued snow through the weekend will be building storm slabs on top of a touchy surface hoar layer.  Be very cautious as slides could occur even on low angle terrain.

    Probabilidad

    Tamaño
    1–2
    Up to 20 cm of snow expected through the night and Friday with mod SW winds will build storm slabs on top of a well developed surface hoar layer. Sheltered northerly aspects are likely areas where this surface hoar is most prevalent.

Weather Forecast

Continued snow expected through the weekend with up to 30 cm accumulated by Sunday night.  Mod SW winds with warm valley bottom temps cooling with elevation. 

Snowpack Summary

A well settled snowpack exists at treeline and below. In the alpine, SW winds have stripped most fetch areas and built pockets of hard slab on lee slopes. The distribution of the surface hoar that formed during last week's inversion is widespread but is most likely best preserved on sheltered north aspect slopes. 

Avalanche Summary

No new activity reported or observed on Thursday. No avalanche patrol conducted.

Confidence

Forecast snowfall amounts are uncertain on Friday
