Avalanche Forecast
Regions: Little Yoho.
Human triggering of large avalanches is likely in many areas. Avoid all avalanche terrain. Ice climbers should be wary of warm temperatures and gullied features.
Weather Forecast
Continued warm spring-like conditions will persist into the weekend. Cloudy skies will reduce overnight recovery. Light snow and cooler conditions are forecast through Saturday.
Snowpack Summary
60 to 100 cm of stiff new snow slab and windslabs, in the alpine and at treeline, overlies an old weak snowpack that is a mixture of facets, crusts and depth hoar. Propagation of weak layers can be very wide. Below treeline, poor overnight recovery and a recent warm spell, create poor snow cohesion.
Avalanche Summary
Some natural activity was noted in the Emerald Lake area was noted today.
Confidence
Avalanche Problems
Storm Slabs
50 to 90 cm of storm snow lays over the Jan 30 crust interface. A weak bond exists on this interface and storm snow avalanches are possible.
- Be aware of the potential for wide propagations.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible - Likely
Expected Size: 1 - 3
Wind Slabs
- If triggered the wind slabs may step down to deeper layers resulting in large avalanches.
Aspects: North, North East, East, South East, South.
Elevations: Alpine.
Likelihood: Possible - Likely
Expected Size: 1 - 3
Loose Wet
Continued warm temperatures have created isothermal conditions below 1800m. Use caution in any steep terrain when the snowpack is isothermal.
Aspects: All aspects.
Elevations: Alpine.
Likelihood: Possible - Likely
Expected Size: 1 - 2
