New snow and wind will make dangerous avalanche conditions especially at higher elevations.
Recent snow and wind has created storm slabs that will be deeper and and more likely to trigger on leeward and cross-loaded slopes.
Retreat to mellower terrain if you find signs of instability like shooting cracks, or recent avalanches.
On Saturday numerous small ( size 1 ) natural storm and wind slabs were reported.
On Friday a few small ( size 1 to 2 ) natural wind slab avalanches were reported in lee features.
If you are getting out in the backcountry, consider making a post on the MIN (Mountain Information Network).
Recent snow ( 15 to 30 cm ) combined with moderate to strong wind have formed wind slabs on leeward slopes. Expect to find soft snow in sheltered areas. A layer of weak, feathery crystals (surface hoar) may be found 30 to 50 cm down.
A 2 to 10 cm thick rain crust can be found down 50 to 100 cm at 1400 m and below.
At treeline we expect a snow depth of 250 cm or more. Snowpack depth tapers with elevation to around 50 cm at valley bottoms.
Many early season hazards are just below the surface below treeline.
Sunday Night
Cloudy. 5 to 10 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -5 °C.
Monday
Cloudy. 10 to 20 cm of snow. 20 km/h southeast ridgetop wind. Treeline temperature -6 °C.
Tuesday
Partly cloudy. 5 cm of snow. 10 to 20 km/h west ridgetop wind. Treeline temperature -12 °C.
Wednesday
Partly cloudy. Up to 8 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -20 °C.
