    Watch for wind slabs behind ridges and terrain breaks. Be alert for wind slabs in atypical places as the wind shifts direction over the next few days.

Snowpack Summary

At treeline, snowpack depths are around 250cm.A hard surface crust exists in many places, even up into the alpine. Surface hoar is growing on this surface. The upper snowpack comprises a series of storm snow layers, which have generally bonded well to each other and are now gaining strength.Recent winds have led to wind slab development occurring on north and east aspects, but also some on south aspects. Concern for lower snowpack layers has diminished and remains only in shallow snowpack areas. Facets associated with a crust from mid-December and/or sugary facets at the base of the snowpack may still be a concern in areas you know to be unusually shallow, or where you can see rocks poking up out of the snow.
