    wind slabs will likely still be found on north and east facing terrain at treeline and above. Expect the most reactive slabs in immediate lee terrain, such as just below ridge tops.

Confidence

Moderate

  • Uncertainty is due to the limited number of field observations.
  • Uncertainty is due to the speed, direction, or duration of the wind and its effect on the snowpack.

Avalanche Summary

No new avalanches have been reported since last weekend.

Snowpack Summary

In open areas at treeline and above, recent snow has been redistributed by strong southerly wind.

A prominent crust, formed in mid-December, is buried 30 to 50 cm below the surface and extends up to 2200 m.

In the mid snowpack, several other crust layers may exist. In the lower snowpack, a crust from mid-November can be found with facets above and below.

The snowpack depth is around 100 cm, tapering with elevation below 1500 m.
