Wind slabs may be reactive at upper elevations. Steep, unsupported rolls and immediate lee terrain are the most suspect.
Summary
Confidence
Moderate - Wind speed and direction is uncertain
Weather Forecast
FRIDAY NIGHT: Cloudy with isolated flurries, light southwest wind, alpine temperatures drop to -10 C.SATURDAY: Cloudy with sunny periods, light wind, alpine high temperatures around -8 C.SUNDAY: Mix of sun and cloud, light wind, alpine high temperatures around -8 C.MONDAY: Mix of sun and cloud, moderate northwest wind, alpine high temperatures around -8 C.
Avalanche Summary
On Friday, several small (size 1) soft slabs were triggered by skiers on upper treeline and alpine features (up to 30 cm thick). On Thursday, skier traffic produced small (size 1) wind slabs near ridges and some minor sluffing in steep terrain.
Snowpack Summary
10-40 cm of recent snow remains low density in many areas, but has settled into thin soft slabs on some higher elevation features. Harder wind slabs can be found in exposed terrain near ridges. You may find a crust beneath this snow below 2000 m and on steep south-facing slopes. In exposed areas, the new soft snow sits above hard wind affected snow. The remainder of the snowpack is generally well-settled.
Problems
Wind Slabs
Small soft slabs may be reactive at upper treeline and alpine elevations. Approach steep and wind affected terrain cautiously.
Caution on steep south-facing slopes where buried crusts may exist.Be cautious as you transition into wind affected terrain.Watch for whumpfing, hollow sounds, and shooting cracks.
Aspects: All aspects.
