Touchy storm slabs now lay on top of a supportive Spring crust. Natural (sun, wind-loading, etc) or human triggering of these new slabs is likely today.
Summary
Weather Forecast
April flurries bring powder skiing back in a hurry. Today will be mainly cloudy with sunny periods, light/moderate SW winds, and freezing levels (FZL) around 1900m. Friday through Sunday will be unsettled with 5-10cm each day, light to moderate SW winds, and FZL at 1900m during the day and dropping to 1600m overnight.
Snowpack Summary
10cm of new snow overnight, accompanied by mod/strong Southerly winds, will have formed thin storm slabs at Tree-line and Alpine elevations. This sits on a strong melt/freeze crust. Below the crust, the snowpack is isothermal in thin snowpack areas BTL. The mid and lower snowpack is strong at Tree-line and above where depths are over 2m.
Avalanche Summary
No new avalanches have been observed in the forecast region over the last several days. Last week, numerous glide cracks were opening up and failing at and below treeline on solar aspects. Suspect there was natural avalanche activity overnight on Alpine lee features with the new snow and winds.
