Avalanche Forecast
Regions: Little Yoho.
If you could bare the cold temps, good riding can be found in wind sheltered terrain. Outflow winds in some areas has affected some lower elevation ski quality.
Weather Forecast
Only a few cm's of snow overnight with lows around -20C. Daytime highs Wednesday around -15C with light SW wind in the morning increasing slightly in the afternoon. Thursday afternoon expect some flurries as moderate to strong SW wind ushers in milder air. Check here for more details.
Snowpack Summary
Up to 20cm storm snow in the last 2 days. The wind has eased however, wind slabs are present in lee areas of the alpine and some treeline locations. 50-70 cm over the Dec 2 crust/facet combo which exists below 2200 m. Shallow snowpack areas (<100cm) have weaker basal facets. Snowpack depths at treeline are from 120-160 cm.
Avalanche Summary
Ski hills report triggering small loose dry or thin wind slabs size 1-1.5. Otherwise no avalanches observed or reported in our region.
Confidence
Due to the number of field observations
Avalanche Problems
Wind Slabs
Previous strong SW winds have created wind slabs in alpine and exposed treeline lee areas. These have been a bit more stubborn than expected but could still be triggered by skiers in steep terrain, especially in the alpine.
- Watch for surface cracking and stiffer surface layers of snow. Avoid wind loaded terrain.
- Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
Aspects: North, North East, East, South East, South.
Elevations: Alpine, Treeline.
Likelihood: Possible - Likely
Expected Size: 1 - 2
