Summary

Weather Forecast

Sunny today, some clouds developing this afternoon, and light winds from the North. Alpine temperatures will go above zero again today, and the freezing level will push above 2400m. Finally a change in the weather starting tomorrow; Wednesday, Thursday, and Friday are each forecasted to receive 5cm a day, with the FL slowly dropping to 1500m.

Snowpack Summary

The spring melt freeze cycle continues. We have another strong surface crust this morning, expect it to break down this afternoon. The snowpack is isothermal in thin snowpack areas BTL, the mid and lower snow pack is strong at tree line and above, where the HS is over 2m. Dry snow can still be found on Northerly aspects in the high alpine.

Avalanche Summary

No new avalanches were observed in the highway corridor, or reported from the backcountry in the past three days. Small loose avalanches are possible on steep solar aspects with the strong solar input. last week numerous glide cracks were opening up and failing at and below treeline, on solar aspects.

Confidence

Problems

Loose Wet

Surface melt-freeze crusts are capping weak isothermal snow in thin snowpack areas BTL and higher on solar aspects. Crusts have been breaking down by mid afternoon. Avoid solar aspects in the afternoon!

Use extra caution on solar slopes or if the snow is moist or wet.Avoid terrain traps, such as gullies, where the consequences of a small avalanche could be serious.

Aspects: East, South East, South, South West, West, North West.

Elevations: Treeline, Below Treeline.
