In sintesi

With a slow clearance tomorrow, storm slab is the main concern after all the new snow, but if the sun starts to shine, greenhousing could increase the loose wet hazard quickly. Think about the terrain above you and avoid runout zones.

Conservative route choices are a good idea tomorrow to allow the new snow time to settle.

Current Snowpack Conditions

125mm of rain has fallen in the last 3days, with snow above 2100m and gale NW winds. Below 2000m, there was limited new snow as the freezing level fluctuated. Above 2000m, limited snow existed before 80cm of snow fell last week, which had a few days to settle. Limited layers of concern exist within the old snow.
