Snowpack Summary

High freezing levels produced moist surface snow up to 2000 m on Friday. As temperatures cool a crust will form.

Surface snow has been redistributed by recent winds in exposed terrain. In alpine areas, up to 10 cm of low-density snow overlies various firm layers. The mid snowpack is generally consolidated and sits above a weak, facetted lower snowpack.
