Avalanche Summary

Reports indicate that storm snow was reactive to skier traffic on Saturday and Sunday during the last storm. Skiers were able to initiate loose dry and storm slab avalanches. Small loose dry avalanches were also capable of triggering storm slab avalanches, which ran far. The likelihood of triggering this storm snow should decrease as the week progresses and a clearing trend prevails.

Snowpack Summary

Upwards of 60 cm of snow accumulated on Sunday. This snow fell on a melt-freeze crust that was formed during Thursday's storm. Reports indicate that the snow is bonding well to the crust in certain areas but that the storm snow can slide on the crust in other areas. Expect the deepest deposits in lee terrain features around treeline and alpine elevations.
