The alpine rating is Loose Wet and Persistent Slabs.
, the treeline rating is , and the below treeline rating is Known problems includeTemperatures have remained high for the past two days with another hot day forecast for tomorrow. Poor overnight refreezes mean the snowpack will quickly weaken with daytime warming. If you plan to get out, start early and finish early.

High
Avalanche Summary
Several natural wet loose avalanches have been observed in the past two days, these have mostly been size 1-2. Larger naturals up to size 3 have been observed in isolated areas.
Snowpack Summary
Alpine/Treeline - Moist surface snow all aspects with weak surface crust forming overnight. This overlies a generally well settled lower snowpack. Feb 03 crust/facets may still exist at high elevations and is buried 100-120 cm deep.
Below Treeline - Moist faceted snow to ground. Most solar aspects are now below threshold for avalanches

Terrain and Travel Advice
- The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
- A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
- Back off slopes as the surface becomes moist or wet with rising temperatures.
- Keep in mind that wet avalanches can be destructive due to their high density.
