Snowpack Summary
Conditions are highly variable in the alpine and at treeline (rock, ice, wind-blown snow). In areas sheltered from the wind, 10 to 40 cm of recent snow lies on a generalized refreezing crust. The upper part of the snowpack, up to 80 cm deep, is moist. The middle of the snowpack consists of alternating well-consolidated snow and refreezing crust.
At mid-mountain, the depth of the snowpack varies from 80 to 200 cm.

Terrain and Travel Advice
- Avoid avalanche terrain during periods of heavy rain.
- The first few hours of rain will likely be the most dangerous period.
Avalanche Problems
Loose Wet
The rain expected on Saturday could destabilize the snow received this week. The new snow rests on a refreezing crust, which provides an excellent sliding surface.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Unlikely - Possible
Expected Size: 1 - 2
