Moderate westerly winds, becoming strong southwesterly later on.Thursday: 5-10 cm new snow. Freezing levels around 1000 m. Moderate southwesterly winds.Friday: 15-20 cm new snow.

Avalanche Summary

Expect human triggered and natural avalanches to occur in steep, wind-affected terrain at higher elevations.

Snowpack Summary

Recent heavy rainfall saturated the snowpack at all elevations and washed away much of the snow at lower elevations. Expect to find a crust buried under 20-30 cm of new snow. Travel in many places is rugged, with many open creeks and early season hazards, although Tuesday's heavy snow will be improving things. Snow depths at 1200 m are around 120 cm.
