20-30 cm of new snow has formed fresh storm slabs at treeline and above.
Use small low consequence slopes to test the bond of the new snow.
Summary
Confidence
Moderate - Uncertainty is due to the limited number of field observations.

Avalanche Summary
No avalanches were reported in this region on Wednesday.
We currently have very limited avalanche observation data from this region.
Please consider posting your observations to the Mountain Information Network (MIN). Photos of current conditions and avalanches are the most helpful.Â
Snowpack Summary
20-30 cm of new snow has formed fresh storm slabs at treeline and above. Lingering wind slabs that were formed earlier in the week may remain reactive in isolated locations at treeline and above.
The recent snow is sitting on a variety of hard snow surfaces, including crusts and wind scoured snow.Â
Below this, there are several crusts in the upper snowpack that may have the potential to produce large avalanches during the next significant warming event.
Terrain and Travel
- Start on smaller terrain features and gather information before committing to bigger terrain.
- Be careful as you transition into wind affected terrain.
- Back off slopes as the surface becomes moist or wet with rising temperatures.
- Caution around slopes that are exposed to cornices overhead.
Problems
Storm Slabs
20-30 cm of new snow has formed fresh storm slabs at treeline and above.
Use small low consequence slopes to test the bond of the new snow.
Aspects: All aspects.
Elevations: Alpine, Treeline.

Expected Size
Loose Wet
Expect a wet loose natural avalanche cycle to occur when the sun comes out.
Avoid big, steep, alpine slopes that are getting cooked by the sun.
Aspects: East, South East, South, South West, West.
Elevations: All elevations.
