Avalanche Summary
No new avalanches reported or observed.
If you go into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).
Snowpack Summary
In the alpine and wind-affected areas of N-NE-E-SE slopes, isolated soft wind slabs were developed in the past 48 hours. Older and stiffer slabs overlying weak facet grains are still found on the same slopes.
In sheltered slopes, about 10 cm of snow overlies a rain/solar crust, formed on February 11, on steep solar slopes.
The mid-snowpack is well consolidated, resting on the December 30 combo of facets and crust. Facets and depth hoar are developing at the base of the snowpack.
Weather Summary
Synopsis: A weak low-pressure system will move in on Friday, bringing a few snow showers and, hopefully, 5 to 10 cm by Sunday.
Thursday evening and night: Partly cloudy. Wind south-west, 20-30 km/h. Minimum -4.
Friday: Increasing cloudiness. Light snowfalls up to 2 cm of snow. Wind south, 20-30 km/h. Maximum -1.
Saturday: Cloudy. Light snowfalls up to 2 cm. Wind northwest, 20-40 km/h. Maximum -10.
Sunday: Mix of sun and cloud. Wind west, 20-30 km/h. Maximum -8.

Terrain and Travel Advice
- Although their spatial distribution is isolated, wind slabs are reactive.
- Be cautious of buried obstacles especially below treeline.
- Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.
Problems
Wind Slabs
Southerly winds have transported the snow to develop new and isolated slabs in start zones, on convexities and in cross-loaded areas. Although small, these slabs are reactive to ski cuts tests.
Aspects: North, North East, East, South East.
Elevations: Alpine, Treeline.
