Avalanche Forecast
Regions: Glacier.
Weather Forecast
An arctic high is moving over us, bringing dry cold weather. We may see a few flurries today and winds should shift to the NW at ridgetop and may reverse load slopes. Friday looks clear and cold, expect temps to drop to the low teens. Saturday we may see a mild inversion as temps start to rise back to around -5'C.
Snowpack Summary
~1m of storm snow is settling into a slab. Strong S-SW winds at treeline and above continue to load lee features, forming deep loaded pockets. Surface hoar layers down ~1m (Nov11) and 1.5m (Nov5) are still a concern. Weak facetted snow exists on high elevation N/NE aspects.
Avalanche Summary
Yesterday, there were several size 2-2.5 slab avalanches, likely triggered by wind-loading. Good visibility after the avalanche cycle from earlier this week showed that many avalanches were propagating widely, likely on the Nov 11 surface hoar. Some were also stepping down to deeper layers, including the Nov 5 surface hoar and the basal facets.
Confidence
Due to the number of field observations
