Summary
Weather Forecast
Continued snow as a series of storms roll over the area. Expecting up to 40 cm accumulated by Tuesday night. Mod to strong SW winds with warm valley bottom temps cooling with elevation.
Snowpack Summary
25 cm new (and more on the way) over a well settled snowpack at treeline and below. In the alpine and TL, strong SW winds redistributing 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.
Avalanche Summary
No new activity observed.
Confidence
Intensity of incoming weather systems is uncertain on Sunday
Problems
Storm Slabs
25 cm of snow so far with a total of 40 cm expected by Tuesday night. Mod to strong SW winds building slabs on top of a well developed surface hoar layer. Sheltered northerly aspects are likely areas where this surface hoar is most prevalent.
Avoid open slopes and convex rolls at and below treeline where buried surface hoar may be preserved.Use caution in lee areas in the alpine and treeline. Recent storm snow has formed touchy slabs.
Aspects: All aspects.
