Snowpack Summary
Most precipitation on Tuesday fell as rain below about 1500 m. There is uncertainty how well the new snow above about 1500 m bonds with the old snow surface. Assess the bond of the recent snow before committing to avalanche terrain and travel conservatively.
Terrain and Travel
- Make observations and assess conditions continually as you travel.
- Avoid lee and cross loaded slopes in the alpine.
Problems
Storm Slabs
Most precipitation on Tuesday fell as rain below about 1500 m. There is uncertainty how well the new snow above about 1500 m bonds with the old snow surface. As you travel, assess the height of new snow and use particular caution if you find more than 20 cm of accumulated dry snow. Assess the bond of the new snow before committing to avalanche terrain.
Aspects: All aspects.
