Avalanche Summary
Reports on Thursday indicate numerous skier controlled and natural loose wet avalanches to size 1.5 on all aspects up to 2000m. Additionally a few explosive controlled moist storm slab avalanches were reported to size 2, 20-30cm deep on north and east aspects above 2000m. Exposure to large overhanging cornices remains a significant concern. As the sun comes out over the weekend I would expect see cornices weaken and loose snow avalanches run from steep sun exposed slopes during the warmest parts of the day.
Snowpack Summary
Up to 20cm of moist new snow fell at upper elevations Wednesday night. Thursday during the day the precipitation fell as rain up to 2000m making the snow surface moist or wet. Subsequent overnight cooling has created thin surface crusts up to 2100m. All this adds to moist new snow from the previous weekend and sits on a well developed crust layer that formed up to 1400m on all aspects except south where it formed up to 1700m. The snowpack is generally well settled and continues to transition into a spring melt/freeze regime. Below 1300m the snowpack may be moist or wet through its entire thickness. In the alpine cornices continue to grow large and ever more overhanging.
