Snowpack Summary
Light precipitation is forecasted to fall on the Southern part of the region on a snow surface that consists of a melt-freeze crust in most areas, isolated windslabs or dry powdery snow in wind sheltered areas in the alpine. In the Northern part of the region, a melt-freeze crust exists on all aspects up to 2000 m, and dryer snow can be found on high northerly aspects. The recent warmer temperatures have helped to strengthen and settled the upper snowpack, especially on solar aspects. Isolated wind slabs may still exist, although they are most likely gaining strength. Surface hoar growth has been noted on shady slopes at higher elevations, and large sagging cornices are becoming weak with daytime warming.The February crust/facet layer is now deeply buried 150-250 cm below the surface. This layer is mostly inactive at this time, but could re-awaken with extended warming, solar influence and large triggers like cornice fall.
