Weather Forecast

Tuesday's forecast is showing 4cm of snow, SW winds of 20km/hr with a freezing level of 2100m.

Avalanche Summary

The avalanche cycle continues with several avalanches observations up to size 3 on all aspects (including windward side).

Snowpack Summary

Widespread wind slabs in the alpine on all aspects. Moist snow on solar aspects. Well settled upper snowpack below 2200m due to recent rain followed by cold temps. Temp crust below tree line. Still seeing Na to size 3.

Problems

Wind Slabs

Wind slabs are found on all aspects. Human triggering is very likely.

Be aware of the potential for wide propagations.Avoid freshly wind loaded features.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Likely

Expected Size

2 - 3

Deep Persistent Slabs

Natural avalanche cycle is continuing with avalanches observed on all aspects.

Pay attention to overhead hazards like cornices which could easily trigger the deep persistent slab.Avoid exposure to overhead avalanche terrain, large avalanches may reach the end of run out zones.

Aspects: All aspects.

Elevations: All elevations.

Likelihood

Likely

Expected Size

2 - 4
