Avalanche Summary
No new avalanches were reported on Tuesday.
Through the prolonged warming event, wet avalanche activity was observed up to size 2.5. Steep rocky terrain and direct solar slopes were the most impacted. Evidence of this natural avalanche cycle will still be visible to backcountry users who head into the mountains on Thursday.
If you are heading into the backcountry please consider posting your observations to the Mountain Information Network.
Snowpack Summary
A dusting of new snow covers refrozen surfaces at treeline and above. Below the crust, 30 to 50 cm of moist snow overlies a variety of layers including a thin sun crust on south aspects.
With prolonged warm temperatures two weak layers of surface hoar, facets overlying a crust are slowly gaining strength. While professionals continue to track these layers they have not produced recent avalanche activity. They are unlikely to be reactive with cooling temperatures.
The lower snowpack is well-settled.

Terrain and Travel Advice
- Watch for unstable snow on specific terrain features, especially when the snow is moist or wet.
- A crust on the surface will help bind the snow together, but may make for tough travel conditions.
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
Problems
Loose Wet
Where the upper snowpack remains moist loose wet avalanches may be possible to human trigger in steep terrain.
