Avalanche Summary
Several natural glide avalanches were reported this week, in the size 2-3.5 range. Wet loose avalanches up to size 2.5 were also observed in response to warming from rainfall and sunshine.
Snowpack Summary
Glide cracks have opened up and pose the threat of large, full-depth releases, especially on steep rocky terrain features at low elevations. Large cornices and ice cliffs pose a threat from above. 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 is frozen. Lately, a lack of consistent overnight freezing has left the snowpack weak and unconsolidated, although some re-freezing has been reported in some areas.
