Regions: Cariboos.

Variable winds and recent convective flurries have created wind slabs on exposed slopes.

Confidence

Good

Weather Forecast

Cloudy with sunny periods and isolated light flurries possible throughout the period. Freezing as high as 1500 m on Thursday then up to 1800 m for Friday and Saturday. Light southwesterly winds are expected for Thursday before increasing to moderate westerlies on Friday.

Avalanche Summary

No new avalanches reported. But neighbouring regions have been experiencing widespread dry loose sluffing in steep terrain, and isolated small wind slab activity in exposed areas.

Snowpack Summary

Variable recent storm snow totals across the region are generally in the 5-25 cm range. The snow surface varies with elevation and aspect with respect to sun and wind exposure, and includes dry new snow, loose facetted snow, wind slabs, and sun crusts. The mid-February crust is down around 10-30 cm where it isn't wind loaded or scoured. The late-Jan crust/surface hoar layer (up to 100 cm deep) and the mid-January surface hoar (80-120 cm deep) are generally dormant, and chances of triggering these weaknesses have decreased. However, triggering may be possible with a large input such as cornice fall, or an avalanche stepping down, especially on slopes that see a lot of sun.

Avalanche Problems

Wind Slabs

Fresh weak wind slabs may be lurking in unusual places. Although not expected to be large, they could take you for a ride.
Avoid exposure to terrain traps where the consequences of a small avalanche could be serious.>Avoid travelling in areas that have been reverse loaded by winds.>Be cautious as you transition into wind affected terrain.>

Aspects: North, North East, East, South East.

Elevations: Alpine, Treeline.

Likelihood: Possible
