Avalanche Forecast
Regions: Little Yoho.
Trace amounts of new snow Thursday, and increased winds may form small windslabs in isolated alpine locations, so watch for these if venturing into wind affected alpine terrain.
The more snow we receive, the more the windslab hazard will increase.
Confidence
Moderate

Snowpack Summary
Wind affect exists in the high alpine, but many sheltered areas are holding soft snow. The mid-pack is generally strong; however, a facet layer can be found near the ground in shallow snowpack areas. At treeline, average snowpack depth ranges from 110 to 140 cm.

Avalanche Problems
Wind Slabs
We have seen a few small windslabs triggered in steep alpine terrain, but many areas exist where this is not a problem. If you are venturing into steep alpine terrain and the surface is wind affected, be careful as this might be enough of a problem to ruin your day.
Aspects: North, North East, East, South East, South.
