Avalanche Summary
Recent reports include cornice fall and loose wet avalanches during periods of warming. Full-depth size 2-3 glide avalanches have been sporadically releasing on rock slabs.
Snowpack Summary
Very large cornices are looming. Glide cracks have opened up and pose the threat of large, full-depth releases, especially on steep rocky terrain features at low elevations. At this time of year, snowpack stability tends to decrease during times of warming (e.g. on slopes receiving sunshine, during rainfall, in the afternoon and at low elevations) and improve when the surface freezes. A buried crust/surface hoar layer from late March, within the upper 1.5 m of the snowpack, is reported to have gained strength, but remains a lingering concern.
