Regions: Glacier.

Spring conditions mean it's all about timing! Start and finish early to avoid slopes before the crusts break down!

Weather Forecast

Mainly sunny today, with a chance of convective clouds this afternoon. The alpine may reach -2 on polar aspects, freezing levels will rise above 2000m, and winds will stay light. High pressure and clear skies will linger until Wednesday, then we get back into a zonal flow from the SW. Thursday to Sunday we could see up to 40mm of precipitation.

Snowpack Summary

We are now into a spring melt freeze cycle. We have a strong surface crust this morning, after a cool, clear evening. Surface crusts will break down by mid-afternoon on steep solar aspects, and BTL. Dry snow can still be found on N'ly aspects above tree line and thin soft wind slabs exist on lee slopes.

Avalanche Summary

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

Confidence

Avalanche Problems

Loose Wet

Surface melt-freeze crusts are capping weak isothermal snow in thin snowpack areas, BTL and higher on soar aspects. Crusts have been breaking down by mid afternoon. Use caution on steep solar slopes.
Avoid terrain traps, such as gullies, where the consequences of a small avalanche could be serious.Use extra caution on solar slopes or if the snow is moist or wet.

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

Elevations: Treeline, Below Treeline.

Likelihood: Possible

Expected Size: 1 - 2.5
