Regions: Glacier.

Spring conditions mean it's all about timing! Start and finish early to avoid slopes once the crusts break down. Poor overnight crust recovery due to above freezing temperatures up to 2000m.

Weather Forecast

A sunny start to the morning, cloud and trace precipitation starting just before noon, freezing level rising to 2000m. Skies clearing on Monday.

Snowpack Summary

We're into the spring melt freeze cycle. At valley bottom the crust this morning was 7cm thick and overlies an isothermal snowpack in most areas. Surface crusts have been breaking down by mid-afternoon on solar aspects steeper than 25 degrees. Dry snow can still be found on N'ly aspects above tree line and thin soft wind slabs exist on lee slopes.

Avalanche Summary

Loose wet avalanches observed yesterday during the heat of the day and on Friday, MacDonald Gully #6 and Connaught slide path were the most notable to size 2.5. An impressive glide crack release on the Mounds path earlier this week came to within 40m of the highway and numerous glide cracks are opening up at and below treeline.

Confidence

Avalanche Problems

Loose Wet

Surface melt-freeze crusts cap weak isothermal snow and the crust has been breaking down by mid afternoon on solar aspects. Use caution on steep slopes when crusts start to weaken, there is very little holding it together once the crust breaks down.
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.

Likelihood: Possible

Expected Size: 1 - 2.5
