Regions: Little Yoho.

Skiing at and below treeline is still rugged. Watch for windslabs at high elevations.

Weather Forecast

Clear skies, light wind and little precip are expected over the next few days. With the exception of solar heating on south aspects, the weather inputs will have little effect on the danger rating.

Snowpack Summary

A generally deeper and well settled snowpack exists in the Little Yoho region compared to East of the divide. There are areas with basal facets in shallow snowpack areas but we have seen little activity on this layer. Below 2000m, breakable melt-freeze crust transitions to bullet proof melt-freeze crust making for rugged skiing.

Avalanche Summary

No new avalanches were reported today in Little Yoho.

Avalanche Problems

Wind Slabs

Recent winds from many directions have formed wind slabs that are susceptible to human triggering. Recent cornice growth is also a concern as these may trigger any deep weak layers that are present in the snowpack.

Use caution in lee areas. Recent wind loading have created wind slabs.
Extra caution needed around cornices with current conditions.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2
