    Likelihood
    Likely - Very Likely
    Size
    1–2
    Up to 20 cm of snow expected through the weekend 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 to strong SW winds with warm valley bottom temps cooling with elevation.

Snowpack Summary

10cm new (and more on the way) over a well settled snowpack at treeline and below. In the alpine and TL, strong SW winds will redistribute the new snow on the lee aspects. 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.
