Avalanche Forecast
Regions: Glacier.
Weather Forecast
The ridge of high pressure is breaking down today. Temps will remain above freezing well into the alpine with frequent sunny breaks. Winds will increase to strong W'ly. On Sat, a cold front will clouds and up to 10mm of precip with freezing levels around 2000m. On Sunday, precip will taper off and temps and freezing levels will start to lower.
Snowpack Summary
No overnight freeze with warm temps. What did tighten will lose strength will lose strength rapidly today. Surface wet grains overly a near isothermal snowpack with various crusts/PWL in top meter. In the alpine, a mix of hard and soft slab persists, with dry snow on polar aspects above 1900m. Lots of variability in snow depth across terrain.
Avalanche Summary
There have been no new natural avalanche observations in the past 3 days, in part due to fewer people in the backcountry to report. Cornice failures remain the biggest concern for triggering larger slab avalanches, which are mostly failing on the April 3 crust-surface hoar, down 40-80cm. Cloud today will reduce the likelihood of moist avalanches.
