Avalanche activity is possible on steep solar aspects if the sun peeks out.
Avalanche Problem 1: Storm Slabs
What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
Travel and Terrain Advice
- Use conservative route selection: choose moderate angled and supported terrain with low consequence.
- Travel on ridgetops to avoid wind slabs on slopes below.
Avalanche Problem 2: Cornices
What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
Cornices are large and fragile in the north of the region: Give them a wide berth and a lot of respect.
Travel and Terrain Advice
- Give cornices a wide berth when traveling on or below ridges.
Avalanche Problem 3: Persistent Slabs
What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
Persistent slabs are most likely to be triggered with a large load like cornice fall; or by a person in a thin or variable-depth snowpack spot.
Travel and Terrain Advice
- Pay attention to overhead hazards like cornices which could trigger deep slabs.
- Avoid convexities or areas with a thin or variable snowpack.
Avalanche Summary
A few sun-triggered avalanches to size 2 were reported on Wednesday. These included a size 2 loose wet avalanche and a skier-triggered wet slab. Storm slabs or cornice fall could potentially step down to a buried weak layer, creating a surprisingly large avalanche.
Snowpack Summary
Recent snow and moderate winds may have created touchy slabs in specific terrain. Cornices are reported to be large and fragile. New snow overlies various old surfaces including melt freeze crusts on sunny aspects, scoured old hard wind slabs and dry snow.
A weak layer consisting of surface hoar, facets or a sun crust buried in late March is now down about 60-80 cm. This is patchy in its distribution, but is mostly likely to be problematic on shady aspects between 1900m and 2250m.
The mid and lower snowpack are strong and well settled.
Weather Forecast
FRIDAY: Light snow. Light to moderate southerly winds. Freezing level near 1800 m.
SATURDAY: Light snow. Light winds. Freezing level near 1900 m.
SUNDAY: Light snow. Light winds. Freezing level near 1600 m.
