Storm and wind slabs at upper elevations are the main concern as the recent stormy period comes to an end.
Several days of stormy weather have formed storm and wind slabs. They will be most problematic at high enough elevations where the ground roughness has been buried.
On Saturday reports of a few small (size 1) moist storm slab avalanches at treeline.
Please consider sharing any observations you have on the Mountain Information Network.
A series of storms over the past week have brought up to 100 cm of snow to upper elevations. The freezing level has fluctuated between 1000 and 1400 meters over the past several days. This has resulted in variable conditions below treeline, where precipitation has been a mix of snow and rain.
The snowpack is generally 150 to 200 cm deep around treeline, with significant snow accumulation in wind-loaded areas. Snow depths rapidly decrease at lower elevations.
Sunday Night
Cloudy with 1-3 cm of snow. 20 to 40 km/h southeast ridgetop wind. Treeline temperature -3 °C. Freezing level 1100 m.
