Avalanche Forecast
Regions: Glacier.
Weather Forecast
Expect mostly dry and clear weather until Friday. Today strong solar with light west winds and an alpine high of -1'C will destabilize the recent storm snow. Thurs will be similar but warmer with freezing levels rising to 2100m, a high 2'C and temps will stay warm overnight. Fri will be increasingly cloudy with showers and freezing levels to 2400m.
Snowpack Summary
Up to 50cm of snow has settled into a slab sitting a crust on solar aspects and surface hoar on sheltered north and east aspects. Wind effected snow at treeline and above. Above 1700m the top 40-50cm is dry with moist or wet snow below it with multiple crusts in the top 1.5m of the snowpack. Sustained warm temps will rapidly weaken the snowpack.
Avalanche Summary
2 size 2 naturals were observed along the highway yesterday, triggered by windloading. On Sunday, skiers triggered slab avalanches to size 1.5 in the Tree Triangle gully at ~2000m, 30-40cm deep, 20m wide and 75m long. In the surrounding region there were reports of cornices triggering slabs, and skier remote's and accidentals to size 2.
