The hazard will increase in the afternoon as the day warms up. This is the time of year to start your trip early.
Summary
Weather Forecast
Minimal re-freeze on Sunday night and another warm day on Monday with freezing levels between 2100-2300 m. Light flurries forecasted with minimal accumulation.
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.
Confidence
Freezing levels are uncertain on Tuesday
Problems
Loose Wet
Warm daytime temperatures and high freezing levels will increase the possibility of a loose wet problem at treeline and below. Even short period of solar inputs may cause a rapid deterioration of the snowpack.
- Use extra caution on solar slopes or if the snow is moist or wet.
Aspects: All aspects.
Elevations: Treeline, Below Treeline.
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.
