Be done your day before the afternoon or when the crust breaks down.
Weather Forecast
Very warm weather is expected. Be done your day before the afternoon.
Snowpack Summary
We are into a spring cycle for most of the little Yoho area except in the high alpine. Occasional pockets of deep instability may still be encountered and triggered from warm or shallow locations.
Avalanche Summary
Only some small loose wet avalanches were noted today.

Avalanche Problems
Loose Wet
Avoid steep slopes or gullies as the day heats up and the crust on top of the snowpack melts. Plan to finish early over the next few days.
Aspects: All aspects.
Elevations: Alpine.
Likelihood: Possible - Likely
Expected Size: 1 - 2
Persistent Slabs
There are several buried sun crusts exist in the upper snowpack and it remains possible to trigger these layers once the surface crusts break down during any prolonged heating from the sun.
- Travel early before the heat of the day, and avoid big slopes in the afternoon.
Aspects: North, North East, East, South East, South.
Elevations: Alpine, Treeline.
Likelihood: Possible - Likely
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.
- Cornices become weak with daytime heating, so travel early on exposed slopes.
Aspects: North, North East, East, South East.
Elevations: Alpine.
Likelihood: Possible
Expected Size: 2 - 3
