Avalanche Forecast
Regions: Little Yoho.
Get an early start and be done before the day heats up. Avoid gullied terrain and exposure to sun-drenched slopes.
Weather Forecast
Warm and sunny for the next few days. get an early start and be done before the heat of the day.
Snowpack Summary
Daytime heating will be the main culprit over the next few days. Watch for cornices and thin areas in the alpine.

Avalanche Problems
Loose Wet
This activity has largely been seen out of fairly extreme terrain with solar heating over the weekend however it was very easy to push the new snow off of buried crusts as it was warming up today. Be careful with terrain traps like cliffs and gullies
- Minimize exposure when the solar radiation is strong, especially if snow is moist or wet.
Aspects: North, North East, East, South East, South.
Elevations: All elevations.
Likelihood: Likely
Expected Size: 1 - 2
Persistent Slabs
Several buried suncrusts exist in the upper pack on S, E and W aspects. These crust are variable by nature and are likely responsible for the slab activity in the area. Heating may make these slabs more sensitive later this week.
- Travel early before the heat of the day, and avoid big slopes in the afternoon.
- Dig down to find and test weak layers before committing to a line.
Aspects: North, North East, East, South East.
Elevations: Alpine, Treeline.
Likelihood: Unlikely - Possible
Expected Size: 2 - 3
Cornices
Cornices are large. Give them a wide berth on ridge crests, as they can pull back a long way when they fail and may trigger an avalanche below. If you need to travel under cornices, move quickly but think twice if there is significant heating.
- Pay attention to overhead hazards like cornices which could easily trigger persistent slabs.
Aspects: North, North East, East, South East.
Elevations: Alpine.
Likelihood: Unlikely - Possible
Expected Size: 2 - 3
