Avalanche Forecast
Avalanche Bulletin - Little Yoho
Good ski conditions exist at higher elevations, but watch for early season hazards and stay out of bigger alpine terrain where the halloween crust is still a concern.

Travel and Terrain Advice
- Use conservative route selection, choose moderate angled and supported terrain with low consequence.
Avalanche Problem 2: Wind Slabs
What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
Up to 50cm of recent dry snow is being blown into windslabs in the alpine. We expect these to only be a problem at the higher elevations where they can be easily triggered by skiers in leeward areas.
Travel and Terrain Advice
- Use caution in lee areas. Recent wind loading has created wind slabs.
- Be careful with wind loaded pockets while approaching and climbing ice routes.
Avalanche Summary
No avalanches were reported or observed today.
Snowpack Summary
Another 10-15cm of new snow overnight on Tues brings the 5-day dry storm snow amount to ~50cm. Moderate winds have been transporting this snow, but windslab formation has been limited in the past 24 hours. The main weakness to watch is the Oct 31 crust/facet layer located about 30cm above the ground which produces easy, planar shear test results.
Weather Forecast
A westerly flow will bring consistent, but light precip amounts this week. 5- 10 cm per day with light to moderate west winds in the alpine and freezing levels staying below valley bottom.
