Pump - Small Avi

Skier in group triggered a small avalanche but was able to ski out of it. This was below pump on the sunny side. The sun exposed sides became weaker as the day progressed and warmed up. No injuries or partial burial. Small crust on top of snow with a weak layer approximately 3-4 inches down where broke. In other areas this layer is 6 inches down.

Was warming rapidly throughout the morning making south slopes feel very unstable. Avalanche (1) triggered on a south sunny slope at 10 am
