Travel advice :

Avalanche problem #1 : Wind slab
What Elevation? Which Slopes? Chances of Avalanches? Expected Size?

Wind slabs that have formed since last weekend may still react to skiers passing over them, particularly in alpine slopes, where the warmth of recent days has had a more limited stabilising effect. They are found in particular beneath ridges, beneath convex features and in the loading zones of alpine couloirs.


Avalanche problem #2 : Wet Loose
What Elevation? Which Slopes? Chances of Avalanches? Expected Size?

Warm temperatures and rain could warm the surface snow sufficiently to trigger small wet loose avalanches. Be particularly mindful of steep slopes, areas near rocky outcrops and terrain traps should a small avalanche occur.


Avalanche Summary

No new avalanches were observed or reported.

If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

In the alpine, south-west to north-west facing slopes have been heavily windswept. On east-facing slopes, there is either fresh snow or wind slabs. Sunny slopes were affected by the warm weather on Thursday and there is a chance of a new crust forming there on Friday morning. A thin sun crust, formed on 4 April, lies beneath approximately 30 cm of snow.

In areas sheltered from the wind, between 40 and 70 cm of snow lies on top of a widespread crust.
