Confidence
Avalanche Summary
Wet avalanches continued to be reported on Saturday, up to size 2.
Activity was concentrated on steep sun affected slopes in the heat of the day. Continued wet avalanches and cornice failures are expected as warming persists.
Snowpack Summary
The upper 30-50 cm of the snowpack is wet from warm temperatures and strong sunshine. This wet snow has a poor bond with the dry snow, or thin crust found below.
The mid and lower snowpack is well settled and dense, however buried crusts exist that may make sliding surfaces for avalanche activity as the warming affects deeper into the snowpack.

- Keep in mind that wet avalanches can be destructive due to their high density.
- Cornice failure may trigger large avalanches.
