7:00 AM Update
Temperatures are on the rise!
Incoming precipitation and high freezing levels are creating dangerous avalanche conditions.
Strong to extreme southwest wind will further redistribute any soft snow still available for transport. Expect stubborn wind slabs deep in terrain features and in sheltered terrain.
Rising freezing levels and rain will soften surface snow. Steep terrain at treeline and below are likely areas to trigger.
On Sunday, during the heat of the day several small wet loose avalanches were human triggered.
Strong to extreme winds continue to heavily wind affect the surface. Wind slabs may be found deep into the terrain and in sheltered terrain.
The wind affected snow sits on a 3 to 10 cm thick crust on all aspects. The thickness of the crust depends on elevation.
A persistent weak layer of surface hoar and/or crust may be found around 70 to 100 cm down. Human triggered avalanches are unlikely on this layer in areas where a supportive crust exists below the recent snow.
In shallow snowpack areas, depth hoar (large facets) can be found near the bottom of the snowpack.
