Regions: Little Yoho.

Great ski and travel conditions exist right now! Watch for sluffing and newly formed wind slabs in steep terrain.

Weather Forecast

Tuesday should see treeline temperatures rising from -15 to -5'C during the day. Alpine winds are expected to be in the light to moderate range out of the West. Some cloud cover and light flurries are forecasted with occasional sunny breaks.

Snowpack Summary

Some wind effect in the alpine from light to moderate West winds. Sun crust on some steep solar aspects. 10-20 cm of storm snow sits over a firm mid-pack. The Jan surface hoar layers down 100-150 cm are rounding and inactive in tests. In shallow areas the deeper facet layers remain weak.

Avalanche Summary

No new avalanches were observed or reported in the Little Yoho area on Monday.

Confidence

Due to the number of field observations

Avalanche Problems

Wind Slabs

Increasing West winds will be moving snow around in the alpine and forming slabs in lee areas. Watch for these especially in steep unsupported terrain where skier triggering may be possible.

Be careful with wind loaded pockets, especially near ridge crests and roll-overs.

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

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 1.5
