Lo esencial

The forecast calls for a cloudy day. If the sun comes out it will increase the potential for triggering loose wet avalanches.

    If the sun comes out, it will weaken the surface snow and increase the likelihood of thin loose wet avalanches running in steep terrain, especially on those slopes facing the sun.

Snowpack Summary

Up to 10 cm of recent snow at upper elevations is bonding well with a variety of snow layers underneath. On higher north aspects above 2000 m it may sit on some dry, faceted snow and/or isolated old wind slabs. At most other places the new snow is sitting on either moist snow or a crust. There are still a handful of melt/freeze crusts, surface hoar and facets in the upper snowpack, but all of these layers appear to have gone dormant for the time being. The snowpack at mid and upper elevations is gaining strength in consecutive nights with below freezing temperatures.
