In sintesi

Winds are forecast to increase tomorrow, which in turn will increase the wind slab hazard. Combined with forecast new snow, the hazard will require good route selection skills for any backcountry travel. Consider runout zones, as the new snow totals get larger, there is enough snow on the ground now for avalanches to run into the valleys.

Current Snowpack Conditions

30mm of rain fell today with snow above 2000m and gale NW winds. This fell on limited snow below 2000m and a variable snowpack above 2000m. Above 2000m limited snow existed before 80cm of snow fell last week which had a few dats to settle. Limited layers of concern exist within the old snow.
