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

Weather Forecast

Sunny skies today with freezing levels rising to 2000m, light ridge top winds and an alpine high of -1. Snow flurries are forecasted for Sunday, bringing 5cm of snow and light winds.

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 up to sz 2.5 during the heat of the day yesterday, MacDonald Gully #6 and Connaught slide path were the most notable. An impressive glide crack release on the Mounds path earlier this week came to within 40m of the highway and the glide crack on Teddy Bear Trees is opening up with the continued warmth.

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.

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
