Freezing level around 1400 m. Moderate southerly winds.Wednesday: 5-10 cm new snow. Freezing level around 1000m. Strong southerly winds.

Avalanche Summary

Loose snow avalanches are likely on steep terrain at all elevations, but may entrain more mass on southerly aspects if the sun comes out.

Snowpack Summary

Recent warm weather has made the surface moist, especially at upper elevations. Below the moist surface, about 30-50 cm snow overlies a thick crust that was buried on January 6. This crust exists up to about 2000m. Mid and lower snowpack layers are considered well settled and generally strong.
