One more morning of clear skies to do some amazing tours before cloud moves in around noon on Wednesday. Should the cloud and flurries develop later the hazard may be higher in areas with prolonged sun exposure.
Summary
Weather Forecast
Wednesday morning will be clear with cloud building around noon and isolated flurries in the afternoon. For Thursday and Friday, cooler temperatures and cloud with isolated flurries is expected. For more details click here.
Snowpack Summary
Surface melt freeze crusts exist on all aspects up to approx. 2300m. On high elevation north aspects dry snow can be found. The mid-pack is well settled but has several persistent layers consisting of crusts and/or facets. These are currently unreactive to skier triggering but may wake up as spring heat penetrates the snowpack.
Avalanche Summary
A ski touring party reported a cornice triggered size three slab on the north side of Cathedral Peak on Sunday. The alpine remained cool on Tuesday with no new activity noted. Lake Louise reported ski cutting wet loose avalanches at and below treeline on Tuesday and isothermal conditions on steep solar aspects below treeline.
Confidence
Timing of incoming weather systems is uncertain
Problems
Loose Wet
Afternoon cloud and flurries should keep this problem to a lower likelihood Wednesday, but if there are periods of solar input expect a rapid deterioration of the snowpack resulting in some loose wet avalanches.
- Use extra caution on solar slopes or if the snow is moist or wet.
Aspects: East, South East, South, South West.
Elevations: All elevations.
Likelihood
Expected Size
Cornices
After several days of warm temperatures cornices are weak and susceptible to failure. Cornices may trigger larger avalanches on slopes below.
- Pay attention to overhead hazards like cornices which could easily trigger persistent slabs.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine, Treeline.
