Snowpack Summary
10-20 cm of snow is becoming moist from elevated freezing levels. Below 1300 m moist snow sits above a thin melt-freeze crust. 50 cm of settling snow sits over a hard crust at higher elevations. Below 700 m surface is a hard crust.
The mid and lower snowpack is well-settled and consolidated.

Terrain and Travel Advice
- Minimize exposure to sun-exposed slopes when the solar radiation is strong.
- Cornices become weak with daytime heating or solar exposure.
- Stay in tune with the physical environment, conditions may change throughout the day.
Problems
Loose Wet
40 -50 cm of snow sits above a thick crust. With freezing levels well into the alpine, brief periods of direct sun could produce natural avalanches cycle on surface layers. A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
Aspects: All aspects.
Elevations: Alpine, Treeline.
