Weather Forecast

A series of storms is expected to bring further snow and wind to this region.Wednesday: Light snow during the day, getting heavier in the afternoon. Expect around 10 cm new snow during the day, then another 20-30 cm on Wednesday night. Freezing levels around 1000 m, which translates to a snow line of about 800 m. 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. Freezing levels around 900 m. Strong southwesterly winds.

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.

Problems

Storm Slabs

Recent snow and wind will likely promote slab avalanche conditions in exposed terrain.

Use caution in lee areas. Recent wind loading has created wind slabs.Avoid steep convex slopes.
